Tunnelling at Bank Station begins
24 May 2017
Construction of a new 600-metre Northern Line tunnel has begun at Bank Underground Station as part of a major upgrade to improve the station and provide additional capacity for passengers.
Due to the site being surrounded by 31 listed buildings, a mechanized excavator will be used to complete the tunnelling rather than a Tunnel Boring Machine (TBM). In addition, the new passenger interconnection tunnels will have to be dug by hand to avoid exposing and damaging the existing tunnel linings. The existing Northern line tunnel will become part of a new central concourse.
The work is due for completion in 2021 and will create a 40% increase in capacity.
Andy Swift, Programme Manager and CPC Partner said "This is 100-year old infrastructure, which has added significant complexities to the upgrade at Bank Station. The start of the tunnelling process is a key phase in the redevelopment programme, which should last around 30 months”.
