Plans in for Greenwich portal of Silvertown Tunnel

16/07/2021 0 Comments J Smith

The Riverlinx consortium has submitted plans showing the Silvertown Tunnel portal on the south side of the Thames in Greenwich.

The entrance is in a deep cutting with approach roads closely entwined with the existing road network to the Blackwall Tunnel:

Renders show the proximity of the tunnel to thousands of new homes coming as part of Greenwich Peninsula masterplan – which have been continually revised up over the past decade.

A portal building designed by architects dRMM sits above the tunnel entrance.

Optimistic render show HGV in general traffic lane – rather than bus lane which will be permitted

Traffic forecasts for the tunnel predate the increase in approved housing numbers.

Riverlinx are constructing the project on behalf of Transport for London. TfL will pay around £200 million, with another £2 billion cost for private consortium Riverlinx who will recover their spend via tolling both the new tunnel and the existing Blackwall Tunnel from 2025.

Over 100 trees are being felled in Greenwich to make way for approach roads.

Red dots indicate increased congestion according to TfL post-completion

Traffic forecasts from TfL predict increased congestion in much of Greenwich after the tunnel completes, with those forecasts drawn up before increased housing in areas such as Kidbrooke and Greenwich.
