Please find below important information regarding upcoming southbound closures of the Blackwall Tunnel.

There are several upcoming southbound closures of the Blackwall Tunnel on 24-26 February, 16-18 March and 13-15 April where southbound traffic will need to seek alternative routes.  All three closures will start at 00:01 on the Saturday morning, with the tunnel re-opened by 05:00 on Monday morning at the latest.  The works are needed to complete the new road layout, as part of Silvertown Tunnel construction.

Across the weekends TfL are asking drivers to:

Plan their routes in advance, check before they travel and consider any potential restrictions on alternative routes, such as height and weight restrictions at Rotherhithe Tunnel or Tower Bridge. 

  • Note that other crossings, including the Woolwich Ferry, are likely to be busier than usual due to the closures and queuing is likely.
  • Use third party apps such as Waze to plan their journey.
  • HGV drivers are asked to consider routes away from central London. 
  • And for bus customers, the 108-bus route will be split in two, with customers advised to change onto the Jubilee Line to cross the river to complete their journeys.  Refunds for the tube part of the journey are available if required.

During the weekend of the 24-26 February, northbound traffic will also be diverted from the A102 via Millennium Way to the Blackwall tunnel entrance from 22:00 on Saturday evening until 08:00 Sunday morning, to allow for additional works to install new gantries across all lanes of the A102.

TfL thank drivers and customers for their continued patience as we edge closer to the opening of the new Silvertown Tunnel in 2025.
