Value Est. £300m
The Bond Street Station Upgrade project will provide much enhanced capacity at this key transport interchange in the heart of London.
The station upgrade will include a new Ticket Hall opening on to Marylebone Lane, a new escalator and passageway to the north end of the Jubilee line platform, a new Step Free Access (SFA) route of lifts and passageways to all platforms and a new congestion relief passageway between the Jubilee line and the Central line. The Project includes works for Crossrail, Cooling the Tube and development of the frame for the new Over Site Development (OSD) building on 354-358 Oxford Street which was demolished to make a working site.
Engineering challenges include the top-down construction of the ticket hall structure replacing the basement of a Listed Building constructed in the 1790s, and demolition of a former bank building built in the 1960’s to provide access to the shafts and tunnels which will form the new passages and escalator shaft providing improved access to the platforms.
The project will deliver increased capacity and step-free access by mid 2017.
