By 2021 the interlinked stations will feature several new escalators, a new station entrance and more room for Northern line passengers.
Our proposals include:
We developed the plans following consultations in 2011, 2012, 2013 and summer 2014.
Fact sheets used during the consultations are available on the Bank and Monument page in Publications.
These improvements are in addition to a new station entrance and step-free access to the Waterloo & City line which is scheduled to be completed earlier as part of a third party development.
We will apply for a TWAO in summer 2014. A TWAO will authorise us to construct the works and give us some compulsory purchase powers.
Documents supporting our TWAO application, including commitments and an Environmental Statement, will be available on the Bank and Monument Publications page from September 9, 2014.
If our TWAO is granted, works could start as early as spring 2016.
Most of the work will be below ground level.
We need two main worksites from which to construct the scheme. The Cannon Street worksite will be in the block-bounded by Cannon Street, Abchurch Lane, King William Street and Nicholas Lane. It will be used to build the new station entrance, lifts and escalators, and will later be redeveloped with new offices and retail units.
The Arthur Street worksite will be used for the majority of the tunnelling works. This means Arthur Street will be closed to vehicles during the works. Access will be maintained for pedestrians and deliveries.
We aim to keep disruption to a minimum during construction and manage environmental impacts with industry best practices.
We will need to close part of the Northern line in 2020 to connect new and existing sections of tunnel safely and efficiently.
Only the Northern line section between Kennington and Moorgate will be affected:
There will be room for displaced passengers on the District/Circle lines and Crossrail, which will be fully operational by 2020. In addition, Thameslink capacity will be up to 24 trains per hour between Elephant & Castle/London Bridge, Blackfriars, City Thameslink and King's Cross.
To further help passengers, we will:
Between them, Bank and Monument stations are served by five Underground lines as well as the DLR.
Currently, 96,000 passengers use Bank station during the morning peak period, about 40,000 of whom are changing between lines.
The two stations consist of three ticket halls, six lifts, 10 platforms, 15 escalators and two 300-foot moving walkways, making one of the largest and most complicated subterranean railway complexes in the world.
