Tunnelling work to expand Bank Underground station in London has been completed.

The tunnelling, which forms part of the programme to expand the size of the station by 40%, has seen more than 1.3km of tunnels constructed since May 2017.

The project to enlarge the station has involved constructing a new southbound running tunnel for the Northern line, with the existing tunnel to be converted into a passenger concourse with six new cross passages linking to the platforms on either side.

Three new escalator barrels have also been excavated to link the Northern line to the DLR and to the new entrance that is being built on Cannon Street, and a new link tunnel will connect the Northern and Central lines.

Huge milestone

Stuart Harvey, Transport for London's (TFL) Director of Major Projects, said: "Bank Tube station is a crucial link between many lines and is one of the busiest interchanges on the Tube network. Work restarted on site again in May and this is a huge milestone for the project.

"Once completed, there will be more space underground for customers to change from one line to another making journeys quicker and more comfortable for those travelling into the City."
