Motorists are warned the Blackwall Tunnel is closed to southbound traffic over the Easter weekend and to avoid the area.

The closure to make way for refurbishment of the 113-year-old river crossing is from 9pm Thursday to 5am Tuesday, April 21-26 April.

As an alternative, the Rotherhithe Tunnel will be dedicated to southbound traffic over the period.

It will operate two lanes in the southbound direction while the Blackwall Tunnel will carry only northbound traffic.

The Woolwich Ferry will also be operating a two-boat service across the Easter weekend (Good Friday, Saturday and Easter Monday 6.10am -10pm and Sunday 9am-9.30pm).

Work completed so far includes the installation of new ventilation fans in the tunnel’s four shafts as well as new lighting, upgraded CCTV and new communication systems installed throughout the tunnel. Work has also begun installing 26 inlets in the tunnel wall, including emergency phones and fire extinguishers, providing a safe area for any drivers whose vehicles have broken down within the tunnel.

Garrett Emmerson, Chief Operating Officer for London Streets, TfL, described the progress as phenomenal and that, as a result, the project is likely to be completed one year ahead of schedule,

She added: “We apologise for the delays and inconvenience that this closure will inevitably cause.”
