TfL advises drivers that the Blackwall Tunnel will be closed to southbound traffic across a number of weekends in May and June to help support carriageway works on the northbound Blackwall Tunnel approach.

The closures are required to help implement the road configuration for the new Silvertown Tunnel which will open in 2025.  The closures will take place across the weekends of

18-20 May,1-3 June, 8-10 June and 29 June-1 July

During these weekends, a range of works will be undertaken, including resurfacing roads and pavements on the tunnel approaches, installing safety barriers, work to retaining walls and landscaping works. The closures will all start at 00:01 on the Saturday morning, with southbound traffic being restored by 05:00 on the Monday morning at the latest. Further information about the closures can be found at www.tfl.gov.uk/blackwall-tunnel.

Across the weekends, the Blackwall Tunnel will be closed for southbound traffic and drivers will need to take alternative routes. Northbound traffic will not be affected by these closures as traffic will be diverted through the southbound Blackwall Tunnel when required. Drivers are advised to plan their routes in advance, checking before they travel so they can consider any other potential traffic impacts or restrictions, such as the height and weight limits at Rotherhithe Tunnel and Tower Bridge, both of which are outside the Congestion Charge zone. Traffic around Rotherhithe Tunnel and along the A13 Commercial Road is expected to be heavier than normal over the weekends due to the closures. The Woolwich Ferry, which now depart every fifteen minutes, seven days a week, will also be in operation across the weekends.

The opening of the new Silvertown Tunnel is getting closer.  TfL appreciate that these planned weekend works will have an impact on some drivers. They are doing everything in their power to limit potential disruption and complete these essential works as quickly as possible, including ensuring a northbound route through the Blackwall Tunnel is maintained throughout.

Work on delivering the tunnel continues to progress. Both of the 1.1km tunnels have now been fully tunnelled, with the ‘cut and cover’ sections now virtually covered. Following approval by local councils, landscaping works in Greenwich are now taking place as worksites are no longer required.

Throughout 2024, work will also continue to install the safety critical systems within the tunnel, as well as complete work on the tunnel portals. Work is also progressing on the new road layout around Tidal Basin Roundabout in Newham, including new walking and cycling paths to make it easier for people accessing the Royal Docks via the Lower Lea Crossing.
