Suntec City
During the station's construction, the arterial routes of Bras Basah Road and Nicoll Highway had to be diverted through more than 10 phases. Road diversions began from 4 August 2002 with the realignment of a stretch of Bras Basah Road and the shifting of Nicoll Highway into War Memorial Park. A pedestrian underpass linking One Raffles Link and Suntec City was closed from 20 January 2003. A sheltered linkway at One Raffles Link and a temporary pedestrian bridge was constructed to facilitate movement between City Hall and Suntec City.
