TfL is looking to award a contract for the design, construct, finance and maintenance of a new river crossing. The maintenance element will run for 30 years.

The crossing will comprise of a twin bore road tunnel alongside Blackwall Tunnel with connections to the A1020 Silvertown Way/Lower Lea Crossing at the north and to the A102 Blackwall Tunnel approach at the south. It is expected to open in 2023.

It is proposed that user charging will be applied to manage congestion and help fund the scheme, although this will not form part of the contract.

The project was approved by the mayor of London last week.
