A new crossing beneath the River Thames is expected to be built in order to improve journey times and increase capacity for traffic crossing the river east of London.
Highways England will be responsible for delivering the crossing, which will see a new tunnel constructed, easing pressure on the existing Dartford Crossing – currently the only road crossing of the River Thames east of London.
The scheme will cost £4.4 billion and will be a 70mph, 13-mile route.
The new crossing will be linked to the road network by a new road north of the river, which will join the M25 between junctions 29 and 30, and a new road south of the river which, will join the A2 east of Gravesend.
Highways England chief executive Jim O’Sullivan said: “This route will greatly improve journeys as well as unlocking more than £8 billion of economic benefits and create some 6,000 jobs.
“The decision for a new crossing east of Gravesend and Tilbury is underpinned by years of studies, assessments and careful consideration of the record-breaking response to our 2016 consultation.
“As we progress there will be further consultation and opportunities to be part of shaping the detail for the area, now and for future generations.”
