Blackwall Tunnel charge planned for drivers
Drivers could be asked to pay a toll charge of £2 to use the Blackwall Tunnel in south-east London to fund a new crossing under the River Thames.
Transport for London (TfL) has proposed a new road tunnel at Silvertown costing £600m and a £150m vehicle ferry at Gallions Reach.
But there is no funding available in TfL's business plan. A toll would raise revenue and discourage congestion, the government body said.
