Work to an entrance at Bank station has begun – with London Underground stating the improvements will “significantly reduce” congestion .

A new ticket hall, four escalators and two lifts will be installed as part of the upgrade to the Waterloo And City line.

Engineers will also construct two 5.5m passenger tunnels to link the entrance close to Walbrook Square with existing platforms.

To enable the £57million upgrade to take place the Waterloo And City line subway, which provides access to and from the DLR and Northern line platforms, will be closed for 10 months from Sunday, November 8, reopening in August 2016.

During the closure, customers changing between these lines will walk via the Northern ticket hall on weekdays, and the Central line platforms at weekends.

Construction work has uncovered the ruins of the historic Roman Temple of Mithras, with archaeologists from the Museum of London recovering more than 30 Roman tablets.

London Underground’s construction programme director Miles Ashley said: “This new Tube entrance will be only a stone’s throw away from the Bank of England – providing direct access to the heart of the City of London’s financial district.

“With a design nod to the City’s ancient Roman past, this upgrade will make journeys swifter and easier for the hundreds of thousands of Tube customers who use Bank station every day.”

Transport for London (TfL), which owns London Underground, has proposed a substantial upgrade to the capacity of the station from 2016 to keep up with increasing demand.

The major upgrade of the six-line interchange at Bank would provide a step-free route between the Northern line platforms, the DLR and street levels.

Tfl has applied for a Transport And Works Act Order, which if granted will give permission to carry out the work.
