Transport for London (TfL) has announced two weekend closures of the southbound Blackwall Tunnel, which are required to support the opening of the new Silvertown Tunnel in 2025.
The closures, which will take place across the weekends of 20-22 July and 17-19 August, will allow for the final road configuration to be implemented, as well as road resurfacing and safety barrier works to be carried out. These dates have been chosen to avoid key events happening in London during the summer. Accros the weekends, the Blackwall Tunnel will be closed for southbound traffic drivers will need to find alternative routes. Northbound traffic will not be affected by these closures as traffic will be diverted through the southbound Blackwall Tunnel when required. The weekend closures will begin at 00:01hrs on Saturday morning, with southbound traffic being restored by 05:00hrs on the Monday morning at the latest.
