Blackwall Tunnel closures

Travel advice for planned closures of the Blackwall Tunnel.

We need to close the Blackwall Tunnel to southbound traffic on a number of occasions. This is for work on a new road layout on the A102, as part of the Silvertown Tunnel Project.

Closure dates and details 

  • Friday 18 October - overnight (23:00-08:00) 

The tunnel will remain open to northbound traffic. At times there may be diversions on the approach, or northbound traffic may be diverted through the southbound tunnel.

Maintenance closures of the tunnel will continue as normal. These take place between 23:59 Saturdays and 07:00 Sunday mornings.

We will keep this page updated if further closures are needed.

Driving

During these closures, plan ahead, check before you travel and allow more time for your journey. 

Southbound traffic: follow signs for diversions.

HGVs and other large vehicles

During closures, use routes away from central London. There are size and weight restrictions on some London river crossings.

Congestion charging will run as normal during the closures.

Buses

Bus 108

Route 108 will not be affected by these overnight southbound closures. Buses will  be escorted through the tunnel throughout the night.
