The UK government has announced a significant funding boost of £590 million for the Lower Thames Crossing, a transformative infrastructure project set to become the nation’s largest road tunnel. The crossing will link Tilbury in Essex with Gravesend in Kent, forming a vital new route across the River Thames.

With an estimated total cost of £10 billion, the 14.5-mile (23km) route includes 2.6 miles (4.2km) of underground tunnels and aims to alleviate congestion at the Dartford Crossing by up to 20%. The project, approved in March after a 16-year planning process and £1.2 billion in preliminary costs, is expected to begin construction in 2026 and open by 2032.

Chancellor Rachel Reeves emphasized the strategic importance of the project, stating, “This is a turning point for our national infrastructure, and we’re backing it with funding to support thousands of jobs and connect communities. The crossing will aid smoother, less congested passage of vital goods from Europe to our regions.”

Transport Secretary Heidi Alexander added, “This project is essential for improving the resilience of a key freight route and is critical to our long-term trade with Europe.”

The Lower Thames Crossing will connect the A2 and M2 in Kent with the A13 and M25 in Thurrock, enhancing connectivity and economic growth. The government is also exploring private financing options to support the project, which has been designated a “national priority.”

Logistics UK, representing the transport and logistics sector, welcomed the announcement. Policy Director Kevin Green said, “Efficient logistics with minimal delays is critical to the delivery of the government’s growth agenda. Our members are delighted to hear that funding has been made available to start work on the long-planned Lower Thames Crossing.”

Despite widespread support, the project has faced criticism from environmental groups. Chris Todd, Director of Transport Action Network, expressed concern over the impact on ancient woodland, calling the decision “absolute madness” and warning that funding the project could divert resources from other regions.

As the government moves forward with this landmark initiative, stakeholders across the public and private sectors will be watching closely to ensure its successful delivery and long-term benefits.
