Construction of the King George Square busway station was announced in March 2005. Construction commenced in early 2006 and the station opened on 19 May 2008 when the
Northern Busway was extended from
Normanby. The lower two levels of the King George Square Car Park were demolished to make way for the station. The heritage-listed
Wheat Creek Culvert (built in 1861) which ran from under
King George Square out into
Adelaide Street was also demolished. A short segment of the culvert has been preserved as a display in the bus station. A bus tunnel had been constructed under
Albert Street to link the station with
Queen Street bus station. The bus tunnel replaced one of the tunnel exit ramps to the Queen Street bus station on Albert Street (see photo below). As part of construction, the space in Albert Street above the new tunnel has been converted into a pedestrian mall, extending the
Queen Street Mall. In conjunction with the building of the station, there was a national design competition for the redevelopment of
King George Square. The winning entry was entitled
A Space in Transition by UrbisJHD. Construction of the Square was completed in October 2009. The re-design of the square and its busway entrances attracted criticism from professional urban designers and the public. When the station originally opened, it included a Transport Information Centre at the Ann Street entrance, this however was closed on 29 September 2012. The station was renamed "City Hall / King George Square" on 28 January 2025, ahead of an eventual renaming to "City Hall". This renaming better reflects the neighbouring
City Hall, and aligns with other major Australian cities' naming conventions. Between 2021 and 2025, a new tunnel was dug between the busway station and Victoria Bridge for the
Brisbane Metro project. The new tunnel opened on 29 September 2025. ==Services==
