Route map

The Silvertown Tunnel is a road tunnel under construction beneath the River Thames in London, England. It will be built from west Silvertown on the north bank to the Greenwich Peninsula on the south bank. On the southern end it will begin at the same location as the existing Blackwall Tunnel but ends up a mile east of it on the northern side, to the east of the River Lea estuary.

It is being promoted by Transport for London and will be delivered through a design, build, finance and maintain contract by the Riverlinx consortium which was awarded in November 2019. The tunnel is intended to reduce congestion through the A102 Blackwall Tunnel and both tunnels will be tolled when it opens in 2025.

The tunnel will include dedicated lanes for heavy goods vehicles and buses. There will be no pedestrian or cycle access^{[1][failed verification]} but a shuttle bus is being considered for cyclists. All future bus routes that will use the tunnel will be zero emission.^{[2][failed verification]}
