A major step forward has been taken in one of the UK’s most ambitious infrastructure projects, as the Secretary of State for Transport has received official recommendations from the Planning Inspectorate regarding the Lower Thames Crossing.
The long-awaited project, aimed at transforming connectivity between Kent, Thurrock and Essex, proposes a new 14.5-mile (23km) route including two road tunnels beneath the River Thames—set to become the longest road tunnels in the UK.
Easing Pressure on Dartford
The Lower Thames Crossing is seen as the long-term answer to chronic congestion at the Dartford Crossing, where more than 180,000 vehicles pass daily. Once complete, the new route will link the A2/M2 near Gravesend with the M25 in Essex, providing a vital alternative for motorists and freight operators alike.
The scheme is spearheaded by National Highways, who submitted their application to the Planning Inspectorate in October 2022. The project was accepted for examination in November 2022, launching a six-month public inquiry which included input from local authorities, residents, environmental groups and transport experts.
Planning Inspectorate Delivers
The examination concluded on schedule, making the Lower Thames Crossing the 56th transport application considered under the Planning Act 2008. The Planning Inspectorate has now passed its findings and recommendation to the Secretary of State, who has up to three months to make a final decision.
Chief Executive of the Planning Inspectorate, Paul Morrison, said:
“The Planning Inspectorate has now examined more than 150 nationally significant infrastructure projects. Our rigorous process ensures community voices are heard while delivering critical transport improvements.”
What the Project Involves
- Two-lane tunnels in each direction under the Thames
- New junctions connecting to the A2 and M25
- Potential to reduce journey times by up to 30 minutes
- Design focused on minimising environmental impact, particularly to the Thames and surrounding countryside
- Estimated to boost the local economy by improving access to jobs, logistics, and trade hubs
The route would pass through sensitive areas in Thurrock and Kent, with environmental mitigation central to the design. A spokesperson for National Highways said, “We’ve worked extensively to ensure this project protects habitats, minimises disruption, and brings long-term benefits.”
Local Reaction
Public feedback has been mixed. While many commuters and business leaders welcome the plans, citing reduced travel times and economic growth, others have expressed concern about noise, pollution, and land loss during construction.
One Thurrock resident posted on social media:
“This will finally take the pressure off the Dartford Crossing – I spend hours stuck in traffic every week.”
However, environmental groups have flagged concerns. Natural England highlighted potential risks to
