In 1967, Freeman Fox and Wilbur Smith Associates released the government-commissioned Mass Transport Study, which proposed a new underground railway. The plan included the Island Line between Kennedy Town and Chai Wan stations. When the Mass Transport Provisional Authority was founded, minor alterations were made with the Sheung Wan to Kennedy Town section cancelled. The government gave approval on the 95-million-dollar construction of the line on 23 December 1980 and work started in October 1982. The first section of the line opened from Admiralty to Chai Wan on 31 May 1985.
Services
The station is situated between Wan Chai and Tin Hau stations on the Island Line. The typical off-peak service is 17 trains per hour in both directions, which is a train every 3–6 minutes. There was a time when there was a special service in operation between Admiralty and Tai Koo on the Island Line due to shortage of train operators. This service was withdrawn after 1 October 1986, about 5 months after the extension to Sheung Wan.
Station layout
The platforms of Causeway Bay station are constructed in a stacked arrangement, with platform 1 above platform 2.
Entrances/exits
Causeway Bay is a primary shopping district in Hong Kong with exits from the MTR leading directly into major outlets such as Sogo and Times Square, which can be accessed through a long, upward sloping pedestrian walkway at Exit A. Unlike other MTR stations, there are three different concourses in Causeway Bay station. After exiting the paid areas through the turnstiles, the other two concourses are inaccessible underground. The west and east concourses were opened on 31 May 1985 with the opening of the station, while the south concourse and Exit A were opened in 1994 with the opening of Times Square.
These are the bus routes found in the vicinity of Causeway Bay station that provide connections with other areas not served by the MTR including Aberdeen/Wah Kwai Estate, Braemar Hill, Happy Valley, Jardine's Lookout, Kennedy Town, Lai Tak Tsuen, Lei Tung Estate, Park Road, Sham Wan/Wong Chuk Hang, Nam Cheong Station/Hoi Lai Estate, South Horizons, The Peak, Tin Wan, Tsing Yi/Cheung On, Wah Fu.
