Transport for London says the Blackwall Tunnel will be closed to southbound traffic from the early hours of Saturday until 5am Monday to help support works to the northbound carriageway on the northbound Blackwall Tunnel approach.

The works, which follow the successful completion of southbound carriageway works to allow for the final road configuration for the Silvertown Tunnel in 2025, will see changes made to Pear Island on the northbound approach to the Blackwall Tunnel. As part of these works, changes will also be made to the northbound carriageway over the weekend to move where three lanes become two on the approach to the Blackwall Tunnel. This will allow more room for workers as works to the northbound carriageway begin. TfL and Riverlinx are committed to ensuring that two lanes through the northbound Blackwall Tunnel are maintained while further works to complete the realignment of the northbound carriageway are completed.

Across the weekend, the Blackwall Tunnel will be closed for southbound traffic and traffic will be required to take alternative routes. Northbound traffic will not be affected by these closures as traffic will be diverted through the southbound Blackwall Tunnel. However, there will be no access to Tunnel Avenue from the A102 at Pear Island across the weekend due to the works.

The northbound on-slip on Blackwall Lane will also be closed and a signed diversion via the Woolwich Flyover roundabout will be in place. 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.

Drivers of HGVs, as well as vans more than two metres in height or weighing more than two tonnes, are advised to consider routes away from central London across the weekend where possible.
