The UK Government has launched a major GBP 1 billion (US$ 1.3 billion) Structures Fund aimed at rejuvenating transport infrastructure across Great Britain—covering the reinforcement and repair of deteriorating bridges, flyovers, and tunnels—while also allocating an additional GBP 590 million (US$ 801 million) to advance the Lower Thames Crossing project.

The construction of the Lower Thames Crossing — a new link between Tilbury in Essex and Gravesend in Kent — is projected to cost around GBP 10 billion (US$ 13.5 billion). The 14.5-mile (23 km) route received approval in March 2025, following a lengthy 16-year planning process that has already incurred £1.2 billion in costs. National Highways anticipates that the project will ease congestion at the Dartford Crossing by approximately 20%. The new road will connect the A2 and M2 in Kent with the A13 and M25 in Thurrock, running from east of Tilbury to east of Gravesend. Approximately 2.6 miles (4.2 km) of the route will be underground, featuring twin tunnels—one for each direction—running beneath the River Thames. Work is scheduled to start in 2026, with the new route expected to open by 2032.
