Bank and Monument together are used by more than 52 million passengers a year. Demand has risen 50% over the last 10 years.
Improving the station is critical to keep London working and growing and is a key part of our plans to increase frequency on the Northern line.
By 2021, the interlinked stations will feature several new escalators, a new station entrance and more room for Northern line passengers. This will increase capacity at the station by 40%.
The modernisation will include:
Our proposals follow public consultations held in 2011, 2012, 2013 and 2014.
The changes we intend to make are in addition to a new station entrance and step-free access to the Waterloo & City line from Walbrook Square. The new entrance will have two lifts, four escalators and a new ticket hall when it opens in late 2017.
We were granted a TWAO by the Secretary of State for Transport on Tuesday 15 December 2015. The TWAO authorises us to construct the works and operate the new section of railway.
The Secretary of State for Transport held a public inquiry into our application in April/May 2015. Our TWAO application documents, Statement of case, factsheets and settlement deed procedure are on the Bank station capacity upgrade page.
All other documents relating to the public inquiry, including those submitted by supporters and objectors are on the website of the Public Inquiry Programme Officer, Helen Wilson.
More than 200 engineers and staff will work on site at Bank 24 hours a day until 2021.The station will remain open to customers throughout the work. Most of the construction work will take place below ground to minimise construction impact on the historically significant site which is bordered by 31 listed buildings.
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.
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, dismounted cyclists 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 City branch in 2020 to connect new and existing sections of tunnel safely. Closures will be as shown below, with reduced frequencies on those sections of the City branch which remain open.
There will be room for displaced passengers on the District/Circle lines and Elizabeth line (currently being built by Crossrail Ltd), which will be fully operational by 2019. In addition, Thameslink frequency 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.
