Railway work included the construction of a short link from the North London Line to the Cambridge main line, allowing trains that had previously used Broad Street to terminate at Liverpool Street. The station was reconstructed with a single concourse at the head of the station platforms, and entrances from Bishopsgate and Liverpool Street, as well as a bus interchange in the south west corner. The Broadgate development was constructed between 1985 and 1991, with of office space on the site of the former Broad Street station and above the Liverpool Street tracks. Proceeds from the Broadgate development were used to help fund the station modernisation.
