Southbound Closure of Blackwall Tunnel – 31 March – 3 April 2023

As part of the Silvertown Tunnel scheme, being constructed by Riverlinx CJV, we are installing a new pedestrian and cycling bridge across the A102. The new bridge will replace the existing 1960s footbridge with a fully accessible bridge built to modern design standards with improved lighting. It has been designed to provide a safe and easily accessible crossing for those walking and cycling, including those using cargo bikes, across the Greenwich Peninsula and has also considered future neighbouring development proposals. The existing bridge will be kept in use until the new bridge is fully opened.

Works on the new bridge are already underway and on the first weekend of April we plan to close the southbound lane of the Blackwall Tunnel while the main span of the new bridge is lifted into place.  The southbound Blackwall Tunnel will be closed from 22:00 on Friday 31 March until 05:00 on Monday 3 April 2023 while works are completed. The northbound Blackwall Tunnel will not be affected by this closure, but drivers will be subject to local diversions on Saturday night from 22:00 until 10:00 Sunday 2 April while the main span is craned into place over the carriageway.

Drivers are advised to plan their routes in advance and alternative river crossings will be busy as a result of the closure.  We have arranged for the Woolwich Ferry to operate across the weekend and users of the 108 bus are advised that services will terminate at Canning Town and North Greenwich and they will need to change onto the Jubilee line to cross the river and complete their journeys.

During the closure of the southbound Blackwall Tunnel, we will take the opportunity to carry out a range of works within and around the Blackwall tunnel, including carriageway repairs on the approach roads to the southbound tunnel, renewing road markings and repairing signage, and cleaning gullies to reduce risk of future flooding. All this will help deliver future maintenance work more efficiently and ensure the tunnel can continue to safely operate. Air Quality Monitors located within the road closure area will also undergo general maintenance.
