The challenge

The iconic and award-winning Silvertown Tunnel is a vital piece of infrastructure to prepare for London’s future population growth and relieve chronic traffic congestion and poor air quality around the existing Blackwall tunnel.

The design of the tunnel includes a 1.4 km twin-bore road tunnel under the River Thames as well as 0.6km of access ramps. It will connect south of the River Thames with the access to the existing Blackwall Tunnel and north of the River Thames with the Tidal Basin Roundabout, in Silvertown.​
