Overview

• 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.
