The background

East London, in the UK, has seen significant population growth with little road infrastructure investment over the last 30 years. To prepare for the future, Transport for London (TfL) will deliver the new Silvertown Tunnel to connect high-growth residential areas, relieve chronic traffic congestion and poor air quality around the existing 122-year-old Blackwall tunnel.  

Transport for London entered a 30-year public, private, partnership agreement with RiverLinx consortium in 2019, comprising; Invesis, Macquarie Capital, Cintra, Aberdeen Standard Investments, and SK E&C. RiverLinx will design, build, finance and maintain (DBFM) the project for 25 years once operational.  

Construction works for Silvertown Tunnel are underway and despite the impact of COVID 19, our selected construction partners have delivered considerable progress on site. By communicating regularly with the client, Riverlinx alongside our partners, have introduced effective measures where possible to drive progress and meet the construction programme. 

Once complete, Silvertown Tunnel will be a modern 1.4km twin-lane road tunnel under the River Thames, linking North Greenwich and Silvertown. The new tunnel will improve the reliability and resilience of the wider road network, reducing journey times for commuters by approximately 20 minutes.
