UK Government Approves £10 Billion Lower Thames Crossing Project

The 14-mile road and tunnel connecting Kent and Essex aims to ease Dartford Crossing congestion and boost economic growth, with construction set to begin in 2026.

The Lower Thames Crossing will feature two 2.6-mile tunnels under the Thames, creating the UK's longest road tunnels with three lanes in each direction and a 70mph speed limit.
The project is expected to nearly double road capacity across the Thames east of London, alleviating severe congestion at the Dartford Crossing, which handles up to 180,000 vehicles daily.
Over £1.2 billion has already been spent on planning and public consultation, with the government exploring private financing options to fund the remaining costs.
Construction is scheduled to begin in 2026, with the road projected to open in 2032, connecting the A2/M2 in Kent to the A13/M25 in Essex.
The project incorporates low-carbon construction methods and aims to leave a legacy of green spaces and skills development, reflecting government priorities for sustainable infrastructure.
