A new Thames tunnel could drive up the cost to motorists using the Dartford Crossing, according to a council report.
The Mayor of London Boris Johnson is behind the proposals for a new tunnel at the Greenwich peninsula, linking it with Silvertown across the river.
A report by Dartford Borough Council raises fears it could put on pressure to increase the cost to cross the Dartford bridge and tunnel to maintain the balance of traffic using each crossing.
The earliest the Silvertown tunnel could open is 2021 and a toll charge is likely to be introduced to fund it. Despite worries the borough council’s report does recommends members support the plans as it could reduce congestion around Dartford.
