A432 bridge construction reaches milestone

National Highways is warning road users that the M4 north of Bristol will be closed to allow steel beams for the new A432 Badminton Road Bridge to be lifted into place.

The M4 will be closed in both directions between junctions 18 (Bath) and 19 (M32) from 7pm Friday, 10th October to 6am Monday, 13th October.

The closure marks a key milestone for the scheme, which will see eight steel beams lifted into place across the motorway, marking the last full weekend closure of the M4 for this scheme and the final major stage of reconstruction.

Once the beams have been lifted into place, the remainder of the new bridge will be constructed with minimal disruption to the motorway below and will be open to the public in early 2026.

The new bridge – 46.5m in length and 20m wide – will span eight lanes of motorway but will be slightly wider.

This is to ensure the road lanes and pavements are wide enough to meet today’s safety standards. The barriers along the sides are higher to keep people walking and cycling safer.

Sean Walsh, Route Manager for National Highways, said: “The beam lift is a huge milestone in the construction of the new bridge, but we appreciate that any road closures can be frustrating for people.

“We need to fully close the M4 because we’ll be lifting eight 80-tonne steel beams into place, and it’s vital that we keep those doing the work and motorists safe.

“Once complete, the new bridge will help reconnect drivers, businesses and the local communities that have been impacted by the closure.”

With 3,000 to 4,000 vehicles using this section of the M4 every hour during peak weekend periods, the closure is likely to cause substantial disruption, and drivers are advised, where possible, to avoid the area and plan their journeys for alternative times.

National Highways thanks people for their patience while carrying out this significant construction work, which will bring smoother, more reliable, and safer journeys for road users.

A diversion for westbound traffic will be as follows:

From M4 junction 18, exit the motorway roundabout to the A46 heading towards Bath
At the A46/A420 junction just past Pennsylvania, take the A420 towards Warmley
At the A420/A4174 junction in Warmley, take the A4174 towards the M32
Join the M32 at junction 1 and head to the M4 junction 19
Follow directions above in reverse for exiting at M4 junction 19

The eastbound diversion will be in reverse.

Constructed in 1966, the Badminton Road bridge was a concrete post-tensioned structure. In July 2023, a planned detailed structural investigation revealed problems on the underside of the bridge, which meant it had to be closed to traffic.

Having considered the options, demolishing and replacing the existing structure was the quickest and most economical approach to restoring this important local link.

Work is progressing well on site, and the new bridge is due to be open to traffic in early 2026.

A417 Missing Link scheme clocks up 2,000,000 hours without incident

Since the A417 Missing Link scheme hit the ground in Spring 2023, there have been nearly 2,000,000 hours of work with no RIDDOR reportable incidents – that’s the equivalent of 8,300 days of keeping workers safe on site.

Excellent safety record on the A417 Missing Link scheme

A RIDDOR reportable incident refers to Health & Safety Executive (HSE) Regulations, which must be followed if a serious incident, or specified injury, or fatality occurs, and is a standard measure across construction to monitor safety performance, all of which could mean delays to the scheme’s delivery.

Around 500 people each day are working on the £460 million transformation of the A417, an important route between Gloucester and Swindon that helps connect the Midlands/North to the South of England. It’s an alternative to the M5/M4 route via Bristol.

Since work began, the improvements scheme has also:

poured over 3,050 cubic metres of concrete
moved 1.6 million m3 of earth
laid 18km of drainage pipes
fitted 1,682 tons of reinforced and structural steel
laid 10,000 tons of road surfacing
progressed building six new bridges

Contractor Kier is carrying out the work for National Highways and is aiming to have the project open for traffic in Spring 2027.

Excellent safety record on the A417 Missing Link scheme — Cowley Lane overbridge bridge lift

Celine Acard, Senior Project Manager for National Highways, said: “Safety is always the number one priority for National Highways. We think nobody should be harmed while travelling or working on our roads and do all we can to try to make that happen.

“For our contractors, Kier, to record over two million working hours without a serious incident is a fantastic achievement. We are pleased that the stringent safety measures put in place on site are paying dividends, and I’m confident that it will continue to do so.”

RIDDOR, which stands for the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013, is a UK law that requires employers and those in control of work premises to report certain workplace incidents HSE. This includes work-related deaths, injuries, specified occupational diseases, and dangerous occurrences (near misses).

Gavin Jones, Project Director for Kier, added: “The health and safety of our people and supply chain is our number one priority, so to see this reflected in this project by achieving no RIDDOR reportable incidents since 2023 is something I am extremely proud of.”

Among measures taken by contractor Kier to ensure safety include a robust Occupational Health and Safety Management system, with the procedures strictly enforced on site; numerous industry-leading, innovative and award-winning processes, tools, and equipment have been introduced to ensure the health, safety and well-being of all team members; an open and honest culture, where everyone on the project has a voice meant issues and concerns could be dealt with quickly; and lessons learned for improvement.

The landscape-led A417 scheme is not only creating a vital transport link in the Cotswolds, but also incorporates world-class environmental practices that respect and enhance the surrounding landscape and habitats, including:

four miles of new dual carriageway connecting the existing A417 Brockworth bypass with the existing A417 dual carriageway south of Cowley
a section to the west of the existing Air Balloon roundabout that will follow the existing A417 corridor. However, the section to the south and east of the Air Balloon roundabout will be offline, away from the existing road corridor
a new junction at Shab Hill, providing a link from the A417 to the A436 towards Oxford and into Birdlip
a new junction near Cowley, to replace the existing Cowley Roundabout
the existing A417 between the Air Balloon roundabout and the Cowley Roundabout is being repurposed. We are converting some lengths of this existing road into a route for walkers, cyclists and horse riders, while retaining other sections to maintain local access for residents.

The latest information on the scheme is available at National Highways’ A417 Missing Link.

£18m loss caused by Severfield bridge faults

Severfield plc, one of the UK’s largest structural steel specialists, has confirmed an £18 million financial hit linked to remedial work on two defective bridges. The announcement has sent ripples through the infrastructure sector, raising fresh concerns over quality assurance, design review processes, and long-term risk exposure in public infrastructure delivery.

The fault, reportedly due to incorrect design assumptions and insufficient load assessments, affects a major logistics infrastructure project—though the client remains unnamed for legal reasons. These issues, detected only after installation, necessitated partial demolition and redesign, sparking a significant cost liability for Severfield.

Timeline of the Project Failure and Financial Fallout

Severfield revealed that the structural issues were discovered during post-installation load testing, which highlighted unacceptable deflections and potential long-term fatigue problems. The bridges, now subject to redesign and reinforcement, were initially hailed as flagship components of a key logistics corridor supporting freight and HGV distribution.

The company has since reached a confidential agreement with the client to jointly address the fault and mitigate further losses, though Severfield will absorb the majority of the remediation cost. Speaking to investors, Severfield noted: “We deeply regret the disruption caused by these bridge defects and are taking all necessary steps to strengthen our quality assurance and engineering oversight.”

This setback contributed to a reduction in Severfield’s adjusted operating margin, which fell to 5.4% from 6.4% the previous year, despite a modest revenue increase to £491.5 million. The total exceptional cost linked to the faulty bridges accounted for more than half of the company’s adjusted profit before tax, which was reported at £32.5 million for the year ending March 2025.

Structural Oversight and the QA Gaps Exposed

While Severfield did not explicitly blame external parties, it acknowledged that flaws emerged from a combination of design misinterpretation and inadequate stress testing. Industry insiders suggest that the issues could point to broader failings in structural engineering validation, especially for complex bridge designs exposed to heavy commercial vehicle loads.

These faults raise questions about whether early-stage risk reviews and third-party audits were sufficiently robust. It also highlights the challenge faced by contractors operating under Design and Build models, where the balance between engineering design, cost containment, and delivery timelines often creates pressure points vulnerable to error.

Financial Implications Beyond the Project

The £18 million loss is the largest single-item hit Severfield has taken in over a decade and follows a string of large infrastructure wins. The company’s share price reacted modestly, with analysts crediting Severfield’s wider portfolio diversification and strong forward order book of £508 million.

Nevertheless, there are lingering concerns about long-term reputational risk and whether future public-sector tenders may be affected. Institutional investors have begun probing governance around project assurance. According to reports, Severfield has now established an internal task force to overhaul its engineering validation protocols.

“This incident, while regrettable, has provided a catalyst for strengthening our internal procedures and client reporting systems,” a company spokesperson confirmed.

Industry-Wide Impact and Future Safeguards

The Severfield bridge faults are not an isolated case. The National Highways Authority recently cited the need for enhanced structural performance monitoring, particularly for bridges constructed using steel box girders and pre-tensioned spans. While no regulatory action has been taken against Severfield, pressure is mounting for an industry-wide response to reduce the risk of similar failures.

The Institution of Civil Engineers (ICE) has called for a revised standard for third-party design checks and post-construction performance audits. There are also growing calls for changes to procurement models, urging clients to favour collaborative design-build-operate contracts that share risk more equitably between client and contractor.

Severfield’s Recovery Strategy

Despite the challenges, Severfield remains committed to its long-term growth strategy. Its India-based joint venture, JSSL, remains profitable, and several high-profile commercial and defence contracts in the UK and Ireland are progressing on time.

The company confirmed that no further losses are anticipated from the bridge issue and that lessons learned are already being integrated into live projects. In the meantime, Severfield has suspended bidding on similarly complex bridge packages until its new QA regime has been externally validated.

“We continue to work transparently with all stakeholders to ensure structural integrity and public confidence in the built environment,” said the board in its closing remarks.

The £18 million loss incurred by Severfield on account of bridge faults is more than a corporate mishap—it is a stark warning to the UK construction sector. With infrastructure reliability under increasing scrutiny, particularly for bridges exposed to heavy vehicle traffic, the case underscores the critical need for robust engineering, clear accountability, and proactive risk management from design through to commissioning.

As Severfield moves to recover and learn from this episode, the broader construction industry must take note: in the business of bridges, shortcuts and assumptions come at a high cost.

DfT orders cost reassessment of HS2 Phase One

The High Speed 2 (HS2) project, envisioned as a transformative high-speed rail network linking London to Birmingham and beyond, is undergoing a significant overhaul. The Department for Transport (DfT) has embarked on renegotiating contracts with major contractors to address persistent issues of cost overruns, delays, and poor management. This initiative follows sharp criticism from the Public Accounts Committee (PAC) and other stakeholders, who have called for a fundamental reset of the project to ensure it delivers value for money and meets its objectives.

Contract Renegotiation: Scope and Stakeholders

The renegotiation process targets the main works civils, stations, and systems supplier contracts, involving four major civil engineering joint ventures:

Align JV: Comprising Bouygues, McAlpine, and VolkerFitzpatrick
Balfour Beatty Vinci JV
Eiffage Kier Ferrovial Bam JV
Skanska Costain Strabag JV

These contracts, critical to the construction of the railway from London to Birmingham, have been criticized for their structure. According to reports, they lack sufficient incentives for timely completion, offer limited penalties for underperformance, and allow contractors to continually renegotiate scope and value, resulting in poor value for money. The renegotiations aim to address these shortcomings by pricing risks accurately, verifying historic expenditures, aligning the baseline schedule, and securing the supply chain’s commitment to new terms.

In February 2025, the Public Accounts Committee published a report titled “HS2: Update following the Northern leg cancellation,” which sharply criticized the project’s management. The report opens with a damning statement: “The High Speed Two (HS2) programme has become a casebook example of how not to run a major project.” It highlighted significant cost discrepancies, with the DfT estimating Phase 1 costs at £45-54 billion, while HS2 Ltd projected £54-66 billion. The PAC’s investigation suggested that the total cost, including inflation, could exceed £80 billion.

The report also pointed to specific failures, such as the lack of a concrete plan for the redevelopment of Euston station, which includes the Network Rail station, the underground station, and surrounding commercial and housing developments. Additionally, a bat tunnel, intended to mitigate environmental impact, escalated costs to approximately £100 million, doubling the cost of that section of the railway. The PAC questioned the balance between environmental considerations and financial efficiency.

Sir Geoffrey Clifton-Brown MP, Chair of the PAC, was unequivocal in his assessment: “The Department for Transport has failed to manage HS2 properly, and as a result, billions of pounds are likely to have been wasted through delays and overspends.” He called for a reset within the DfT, emphasizing the need for skilled staff to oversee the project and restore the department’s reputation. He expressed hope that future examinations would show improvement.

Table: Key Issues Highlighted by the PAC

The HS2 project has faced ongoing scrutiny for its escalating costs and management issues. Former HS2 Ltd chair Jon Thompson noted that the original contract structures were a primary reason for cost increases, as they provided little incentive for efficiency and minimal ability to penalize poor performance. Transport Secretary Heidi Alexander, in December 2024, acknowledged external factors like Covid and high inflation but also criticized the project’s management, citing cost underestimation and low productivity.

The Guardian reported on 22 October 2024 that contractors had taken advantage of poorly structured contracts, with Transport Secretary Louise Haigh describing the project’s delivery as “dire”. Additionally, a Construction News article from 14 March 2025 quoted a Balfour Beatty executive expressing scepticism about achieving significant savings through renegotiation, highlighting the challenge of aligning contractor and taxpayer.

The HS2 programme is undergoing a “fundamental reset,” as described by HS2 chief executive Mark Wild in December 2024. Speaking to the PAC, Wild confirmed there would be no re-procurement of existing contracts but emphasized immediate efforts to “bear down on costs,” particularly in the main works civils elements. HS2 chief financial officer Alan Foster noted that contractors recognize the need for better-aligned incentives, stating, “There’s a recognition that we need to find a better alignment of incentives between the taxpayer and the delivery of the works.”

The reset includes shifting more risk to the supply chain to enhance accountability. The DfT and HS2 Ltd are working to ensure that new contract terms are sustainable and deliver value for money. Official documents from GOV.UK indicate that recent contract awards for rail systems were approved by the Investment, Portfolio and Delivery Committee (IPDC) and subjected to rigorous Treasury and Cabinet Office oversight, with a focus on long-term affordability through the 2025 Spending Review.

However, the PAC remains unconvinced that contractors have sufficient incentives to agree to significant changes, warning that financial pressures could be passed down to smaller enterprises in the supply chain, which may struggle to absorb them. The committee has called for regular progress updates on renegotiations and a clear plan if favourable terms cannot be secured by the 2025 summer recess.

The renegotiation of HS2 contracts represents a pivotal moment for the project, aiming to address deep-seated issues of cost, efficiency, and accountability. While the DfT and HS2 Ltd are committed to a comprehensive reset, scepticism persists about the feasibility of achieving significant savings. The success of these efforts will be closely monitored by stakeholders, parliament, and the public, who are eager to see HS2 deliver on its promise of transforming UK rail connectivity.

Steel framework rises at Britain’s largest gigafactory in Somerset

We are witnessing a defining moment in the UK’s green industrial revolution as the first steel structures are now being erected at the future site of the country’s largest gigafactory, located in Bridgwater, Somerset. This £4 billion mega project, led by Agratas (a Tata Group enterprise), aims to produce over 40GWh of battery cells annually—enough to support 500,000 electric vehicles per year.

Spanning over 620 acres at the Gravity Smart Campus, this new battery manufacturing plant will play a critical role in securing the UK’s position within the global electric vehicle (EV) supply chain, while revitalising local economies through thousands of direct and indirect jobs.

Precision Engineering: Steel Assembly Now Underway

Construction has now entered its vertical phase with the first steel components craned into position in late June 2025. The framing marks the initial structure of Building A, which will house the cell assembly lines and electrode processing halls. These industrial spaces demand millimetre-level precision and robust, vibration-resistant foundations, designed to support cleanroom-grade environments essential for lithium-ion cell production.

The speed of progress follows meticulous groundwork, including deep piling, utility routing, and environmental groundwork to mitigate flood risk and ensure habitat preservation on this former airfield site.

Clean Energy and Circular Supply Chains at the Core

Designed with sustainability at its heart, the Somerset gigafactory will integrate solar PV, rainwater harvesting, and advanced heat recovery systems to lower operational emissions. The site is also targeting a future link to local wind generation assets, positioning it among the most energy-efficient battery facilities in Europe.

Crucially, a major emphasis has been placed on the development of a circular battery ecosystem. Plans are already in motion for on-site battery recycling and the establishment of secure supply chains for raw materials such as nickel, lithium and cobalt. This will reduce dependency on volatile global markets while improving the factory’s ESG credentials.

Regional Regeneration: Employment and Skills Legacy

The gigafactory is expected to directly create up to 4,000 jobs in Somerset and contribute to the generation of around 11,000 supply chain roles nationwide. Working in collaboration with local colleges and national skills initiatives, the project is establishing a battery technology training academy to develop next-generation engineers and production technicians.

Investment in upskilling will be pivotal, with the site aiming to employ a 60% local workforce by the time full production begins in 2027. Apprenticeship schemes, STEM outreach programmes and graduate recruitment campaigns are already underway, underlining a long-term commitment to regional economic transformation.

Strategic Importance for UK EV Supply Chain

Located just off the M5 corridor and near Bristol Port, the Somerset site has been strategically chosen for logistical connectivity to both domestic vehicle manufacturers and international export routes. Major automotive clients, including Jaguar Land Rover and other Tata Motors affiliates, are expected to be among the first to benefit from the gigafactory’s output.

In a post-Brexit environment, securing sovereign battery production is vital to meet rules-of-origin regulations under the UK-EU Trade and Cooperation Agreement, while also reducing exposure to overseas supply chain disruption. The facility will directly support the UK’s ambition to end the sale of new petrol and diesel cars by 2035.

Community and Environmental Stewardship

The developers have worked closely with Sedgemoor District Council, the Environment Agency and local stakeholders to address community concerns and embed sustainability from day one. Biodiversity net gain commitments include wetland habitat creation, protected species relocation and new green corridors for wildlife.

Community benefit funds and local business incubation hubs are also planned, helping ensure that the wider Bridgwater area shares in the prosperity this investment will bring.

Final Foundations for a Battery-Powered Britain

With the first steel frame now standing, Britain’s flagship gigafactory project is transitioning from concept to reality. The build signals not just the emergence of a new industrial landmark, but a generational shift in how the UK powers its vehicles, economy and future.

This steel is more than structure—it is a symbol of the UK’s charge toward electrification, energy security and long-term industrial resilience.

14 BESA Member Firms Suspended Over Non-Compliance

The Building Engineering Services Association (BESA) has taken decisive action by suspending 14 member companies from its directory following a recent audit of compliance procedures. This decision, made public in June 2025, underscores BESA’s commitment to upholding professional standards in the building services sector.

BESA’s suspension of these firms follows internal reviews that uncovered multiple breaches relating to competency standards, certification gaps, and failure to meet the updated regulatory requirements introduced under the Building Safety Act. This development has sparked serious discussions across the construction, HVAC, and building engineering sectors about quality assurance and the integrity of supply chains.

What Prompted the Suspensions?

According to industry sources, the suspended companies failed to provide adequate evidence of their continued competence and compliance with mandatory technical standards. Areas of concern included:

Lapsed technical accreditations, particularly around health and safety, gas and ventilation installations
Failure to meet CPD (Continuous Professional Development) requirements for key operatives
Incomplete or outdated documentation relating to competency certifications
Non-adherence to Building Safety Act provisions, especially concerning high-risk buildings

These suspensions are not permanent, but the companies in question must remedy their deficiencies and undergo a thorough reassessment before rejoining BESA’s membership roster.

The Impact on Contractors, Clients, and the Wider Supply Chain

Suspension from BESA’s membership list can have substantial repercussions. Many clients and main contractors rely on the BESA directory to source qualified, vetted suppliers. Losing BESA accreditation can:

Jeopardise existing contracts, especially on public sector or framework projects
Invalidate tender eligibility for clients requiring BESA affiliation
Damage company reputation, leading to lost business and long-term trust issues
Undermine supply chain confidence, increasing compliance scrutiny on partners

For the wider industry, this situation serves as a warning against complacency in standards verification. With heightened regulatory focus post-Grenfell, particularly around building safety and mechanical services, lapses in compliance can no longer be tolerated.

Strengthening Governance Across Building Services

BESA’s actions highlight the necessity of robust internal governance. Firms seeking to protect their reputation and eligibility must prioritise:

Routine internal audits to ensure certification and qualifications remain valid
Proactive CPD investment to keep pace with regulation and innovation
Comprehensive record-keeping to support compliance demonstrations during inspections
Early adoption of digital compliance tools, including automated certification tracking systems

Recommendations for Affected Businesses

Suspended firms should act swiftly to restore their status. Key actions include:

Engaging independent compliance consultants to identify gaps
Scheduling urgent re-training for technical staff
Auditing all project files and updating documentation
Engaging directly with BESA’s technical compliance team to confirm remediation pathways

Demonstrating transparency and commitment to rectifying issues is critical in expediting reinstatement.

The Role of Accreditation in a Post-Grenfell Environment

Since the Grenfell Tower tragedy, regulatory bodies have imposed strict scrutiny on the credentials of contractors working on buildings—especially high-rise and high-risk residential blocks. BESA’s response aligns with this climate of zero tolerance for lapses in competence.

The Building Safety Regulator (BSR) now works in tandem with professional bodies to monitor industry standards. Companies must expect continued cross-referencing of accreditations, certifications, and audit outcomes across multiple databases and licensing bodies.

Final Thoughts

The suspension of 14 BESA members marks a turning point in the construction and engineering services sectors. It serves as a sobering reminder that accreditation is not a one-off badge but an ongoing commitment. Industry leaders must embed compliance and training into their core operations—not as a formality, but as a cornerstone of sustainable, accountable business practice.

HS2’s Brackley A43 Bridge

The High Speed 2 (HS2) project represents a transformative endeavour in the United Kingdom’s transportation landscape, aiming to enhance connectivity between major cities and regions. A pivotal component of this project is the construction of the A43 bridge near Brackley, Northamptonshire. This bridge is designed to facilitate the passage of high-speed trains beneath one of the region’s most vital roadways, exemplifying modern engineering prowess and strategic planning.

The A43 serves as a critical arterial route, linking Oxford, Brackley, and Northampton. It provides essential access to the Silverstone Circuit and connects major motorways, including the M40 and M1. Ensuring the seamless operation of this route during HS2’s construction has been paramount to minimise disruption to commuters, local businesses, and event-goers.

In 2023, preparatory efforts commenced with the realignment of the A43 to create an ‘island’ between the carriageways, accommodating the new bridge deck. This strategic move allowed traffic to continue flowing while foundational work progressed. Engineers implemented a ‘top-down’ construction approach, installing 52-metre-deep piled foundations to support the forthcoming structure. This method not only ensured stability but also reduced the project’s environmental footprint.

A significant milestone was achieved with the installation of seven steel beams, each extending 66 metres in length. These beams form the backbone of the bridge, supporting the deck that will eventually carry the A43 over the HS2 railway. The installation process was meticulously planned over three weekend closures to minimise public inconvenience. A 750-tonne crane was employed to position these colossal beams accurately, showcasing the project’s logistical precision.

Following the successful placement of the steel beams, attention shifted to constructing the concrete deck and parapets. Once completed, traffic will be redirected onto the new bridge, allowing excavation beneath to create the railway passage. This phased approach underscores the project’s commitment to maintaining traffic flow and public safety throughout the construction period.

Collaborative Efforts and Stakeholder Engagement

The project’s success is attributed to the collaborative efforts of multiple stakeholders:

HS2 Ltd: Oversaw the project’s execution, ensuring alignment with national infrastructure goals.
EKFB: A consortium comprising Eiffage, Kier, Ferrovial Construction, and BAM Nuttall, responsible for delivering the 80-kilometre stretch of railway encompassing the A43 bridge.
National Highways: Worked in tandem with HS2 to devise strategies that minimised traffic disruption, including synchronising road closures with routine maintenance tasks.
Kier Transportation: Played a pivotal role in the beam installation process, bringing specialised expertise to the project’s critical phases.

The construction of the A43 bridge near Brackley stands as a testament to modern engineering and inter-agency collaboration. By integrating advanced construction techniques with strategic planning, the HS2 project not only advances the UK’s transportation infrastructure but also sets a benchmark for future developments. As the project progresses, it continues to embody the nation’s commitment to enhancing connectivity while prioritising public convenience and safety.

Lower Thames Crossing raises the bar with 70% carbon target

National Highways’ Lower Thames Crossing has today (4 February 2025) revealed a new target to reduce its construction carbon emissions by 70%; an ambition made possible thanks to the project’s Delivery Partners’ and suppliers’ commitment to making the new crossing the greenest road ever built in the UK.

The improved new target has been published in the project’s second annual sustainability report, which details the legacy the project aims to leave for the local community, environment, and the UK’s construction industry.

The Lower Thames Crossing is a proposed new road and tunnel under the Thames designed to tackle congestion and unlock economic growth by almost doubling road capacity across the Thames east of London and creating a reliable route that better links the north and the midlands with the ports of the south-east.

The project is a carbon pathfinder project that is aiming to set new standards for building infrastructure by pioneering and scaling up approaches to low-carbon construction. By working closely with its three Delivery Partners and supply chain the project has halved its predicted construction carbon footprint, and it became the first major project in the UK to make it a legally binding limit when it submitted it in its application for Development Consent in October 2022.

The project has now identified ways to potentially reduce that footprint further, and has set itself an ambitious new target of less than 840,000 tonnes in total – a cut of around 70% against its original prediction. This would be achieved by taking a forensic approach to reducing carbon as the design of the new road is refined, and committing to only using low-carbon steel and concrete. It also includes removing all diesel from its construction sites by 2027, by accelerating the large-scale use of electric vehicles and plant, and using hydrogen to power its heavy construction machinery – a first for a major project in the UK. The award of the contract for the supply of hydrogen is expected to take place later this year.

The project is also in the final stages of running a low-carbon footbridge contest to find a sustainable design for a bridge over the A127, which could also be used across the wider road network.

Katharina Ferguson, Supply Chain Development Director, Lower Thames Crossing said: “The Lower Thames Crossing will not only tackle congestion and unlock economic growth in the UK, with our partners and suppliers we will create a new blueprint for how we build low-carbon infrastructure and leave a legacy of jobs, skills and green spaces for the local community. With millions invested in local projects and a new community woodland at Hole Farm on track to open next year, we’re already making a difference, well before work on the new road gets underway.”

The plans to make the Lower Thames Crossing the greenest road ever built in the UK include building a tunnel rather than a bridge to avoid protected wetlands and marshes, and seven green bridges that would provide safe crossing points for people and wildlife. The project is planting at least 1 million additional trees, creating a new community woodland at Hole Farm and new public parks in Thurrock and Gravesham. The project will also promote active travel by creating or improving almost 40 miles of pathways for walkers, cyclists and horse riders, 3 miles of path for every mile of road.

The project’s latest sustainability report highlights recent successes such as:

The team is ready to start construction as soon as the green light is given by government, with detailed design work to reduce local impacts well underway.
Local communities are already benefitting from the Lower Thames Crossing’s £250,000 Community Fund. An active travel scheme at Cyclopark in Gravesend was one of 55 local charities or not-for-profit organisations to receive money from the fund.
Prisoners on day release and local people seeking employment were the first to take part in the project’s Skills Hub pilot programme – designed to develop local skills and supply chains and address industry skills gaps.
Work got underway on the community facilities at the new Hole Farm community woodland near Brentwood, due to open in 2025 – around 80,000 trees have been planted so far, using low-carbon construction methods.

Subject to planning permission and funding, construction is expected to take six-years. The Secretary of State for Transport recently announced that the deadline for a decision on the Lower Thames Crossing’s planning application has been extended to 23 May 2025.
