The Silvertown Tunnel will cost a billion pounds, raised from tolling Blackwall and Silvertown. Have you and TfL ever sat down and worked out what you could achieve, in terms of greenhouse gas emissions reduction, and air quality improvements, if you tolled the Blackwall Tunnel enough to remove congestion, and invested the money in cycling, walking and public transport instead?

The Silvertown Tunnel scheme has been demonstrated to be the best solution to the well-known problems at Blackwall Tunnel. Transport for London’s (TfL’s) modelling demonstrates that introducing a charge at Blackwall Tunnel, without providing an alternative route, would have a limited impact in addressing the serious congestion on the approaches to the crossing, would not resolve the significant issues with poor reliability, and would not enable a step-change in cross-river bus connectivity.

Furthermore, simply increasing the charges further to try and reduce demand would result in the dispersal of a significant proportion of the traffic onto the surrounding network, thereby exacerbating congestion and poor air quality elsewhere. It would also have a significant adverse impact on the operation of adjacent river crossings, both of which have considerably less capacity than the Blackwall Tunnel.
