Motorists travelling across the Thames between Kent and Essex could benefit from quicker journey times and less congestion if Highways England's plans for a new road tunnel go ahead.
The newly unveiled plans have been broadly welcomed by the RAC, although the motoring organisation is stressing the importance of minimising disruption to motorists while the tunnel is being built.
A consultation on the Lower Thames Crossing has been launched and will continue until March 24.
If the scheme gets the green light it could be open to traffic within 10 years, taking up to 77,000 vehicles a day under the Thames.
Highways England estimates the Government-funded project would cost between £4.3 billion and £5.9 billion.
The new route, designed to ease congestion at the Dartford Crossing, would take motorists from the top of the M2 near Rochester in Kent, run beneath the Thames to the east of Gravesend and link up with the M25 in Essex between junctions 29 and 30.
If built it will be the first new Thames crossing to the east of of London since the Queen Elizabeth II bridge, which runs between Dartford and Thurrock, opened in 1991.
