The footbridge dating from the 1970s that linked platforms for passenger interchange was also demolished, replaced by an interchange concourse underneath the platforms accessed by lift, stairs and escalator. This required the demolition of brick vaults between Stainer and Weston Streets, which were pedestrianised and became part of the new concourse. A wider route was created through the Western Arcade to Joiner Street and the underground station by relocating existing shops in to renovated barrel vaults. Two major new street level entrances were opened to the south on St Thomas Street, and to the north, on Tooley Street. This required demolishing the 1893 SER office building.
