Description

The major upgrade to the LU Tottenham Court Road Station has been proposed to relieve congestion, achieve step-free access and modernise the station. The major elements of the station upgrade comprised a new enlarged sub-surface ticket hall, a fire-fighting access / emergency escape shaft linked to both Central and Northern lines, a triple escalator barrel, and concourses to the Northern and Central lines. In the latter concourse two new overbridges were included to lead to the platforms via new stairs and lifts. For the tunnelling works, a particularly challenging part was to design and construct the two SCL overbridges over the operational Central line.
