Across the weekend, the Blackwall Tunnel will be closed for southbound traffic.

The closures will be from 12.01am on Saturday, April 13 until 5am on Monday April 15, and drivers will need to take alternative routes.

Northbound traffic will not be affected by these closures.

Drivers are advised to plan their routes in advance, checking before they travel so they can consider any other traffic impacts or restrictions, such as the height and weight limits at Rotherhithe Tunnel and Tower Bridge.

Traffic around Rotherhithe Tunnel and along the A13 Commercial Road are expected to be heavier than normal over the weekend due to the closure.

The route 108, the only bus route that operates through the Blackwall Tunnel, will be split in two, operating between both Lewisham and North Greenwich and between Canning Town and Stratford.

Customers are advised to then change onto the Jubilee line to cross the river to complete their journeys.

Customers of the route 108 who then use the Jubilee line as part of their journey over the weekend will avoid being charged for the Tube section of their journey via an automatic refund which will be processed after the weekend.

From 12.01 on the Monday mornings of the closure, northbound buses will return to their normal route and southbound buses will be diverted via Tower Bridge until the tunnel is re-opened to southbound traffic.

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.

To help inform drivers, signs will be placed on the main roads approaching the Blackwall Tunnel.

TfL has also worked with third party app providers, such as Waze, to help ensure drivers who regularly use the Blackwall Tunnel are alerted to the southbound closure and that the closure is shown in any route-planning over the weekend.

Carl Eddleston, Director of Network Management and Resilience at TfL, said: "We appreciate that these planned weekend works will have an impact on some drivers and are doing everything in our 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."
