Scheme details

In planning or on hold
New road for use by all traffic
£ 4-6bn
Highways England
Region: South East

A new crossing of the Thames Estuary, east of London, to increase cross-river capacity for road traffic, relieve congestion on the Dartford Crossing, and improve the reliability of journeys.

This scheme was first announced in 2009.

The current proposal, as of January 2016 is to build a new dual-carriageway road between the M2 in Kent (with a connection around junction 1) and the M25 in Essex (between J29-30). A range of options for the route of road links between the tunnel and the existing road network are being considered. The location for the tunnel itself has now been chosen, and it would cross the river just to the east of Gravesend and Tilbury. Highways England's preferred option is for a twin-bore tunnel.
