Your plans for the Silvertown Tunnel would increase capacity for car traffic by one lane in either direction and meet what Transport for London see as the current demand for use of the Blackwall Tunnel, forecast to be 150% of existing capacity. Can you confirm that the logic of your proposal is to meet what you see as existing demand, which manifests itself as queuing on the approach roads?

Answer for Silvertown Tunnel

Answered By: 
The Mayor

There is a need for a new road tunnel at Silvertown because:

• It will approximately double cross-river highway capacity in the Blackwall area. This is essential to support growth, which is particularly important since London's population is forecast to grow by more than 1.1m by 2031. The east sub-region is predicted to account for more than a third of this growth. TfL has identified user charging and strategic traffic management as essential tools to ensure demand for the Silvertown tunnel could be kept to manageable levels.

• The proposed tunnel will also provide a much greater level of resilience. An unplanned incident at Blackwall tunnel can cause significant congestion throughout the area. Between January and September 2012, there were between 93 and 144 unplanned incidents at Blackwall per month. The Silvertown tunnel would provide a nearby diversionary route, greatly increasing the resilience of the local road network to cope when there are incidents at Blackwall tunnel.
