Causeway Bay station

Causeway Bay is an underground metro station on the MTR network in Hong Kong. It is located between Wan Chai and Tin Hau stations on the, and sits underneath Great George Street near Hennessy Road and Yee Wo Street. Named for the Causeway Bay area and its abundant shopping centres, the station serves various malls including Hysan Place, Sino Plaza, Sogo, and the nearby Victoria Park.

A line servicing Hong Kong Island had been part of the initial 1967 plans for a metro system in the city. The Island line would be approved in 1980 while construction began two years later. In 1985 the station opened along with the first section of the line, which would be extended westward toward Kennedy Town in 2014. The station consists of two separate concourses situated atop two platforms stacked vertically due to geographical constraints and has 6 exits.

Planning
In 1967, the government of Hong Kong saw the need for a public transport system. British transport consultants Freeman, Fox, Wilbur Smith & Associates were commissioned to write the Mass Transport Study, which proposed a new underground railway. The plan included the between Kennedy Town and Chai Wan stations, as well as the Kwun Tong line, Tsuen Wan line, and the Shatin line. Three lines would become part of the early stages of the MTR, while the Shatin line would eventually be shelved and never built. Concerns that the Island line would be prohibitively expensive at a time where the MTR was not profitable led the public to believe the government favoured light rail; however, the Transport Advisory Committeethen the agency responsible for public transportation planningconfirmed that fears of surface construction disrupting the main artery of the island would mean the underground metro was ultimately chosen.

As late as 1980, plans instead named the station "Valley". Causeway Bay was one of the stations planned for above-station property development, along with Admiralty, Wan Chai, and Western Market.

The Island line was built last; by the time construction had started in October 1982, the Kwun Tong and Tsuen Wan lines were already operational.

Construction
At least 5,000 local residents were rehoused to accommodate construction of the Island line.

Contract 405 for the construction of the station and tunnels was awarded to Kumagai Gumi, and civil works began in October 1982. The joint venture between Marples Ridgway and LTA also built the station's structure.

The station construction site was sold by the MTR in 1984 to Taisei Corporation for $380m, now the location of Sogo Hong Kong. The station opened with the first section of the Island line from Admiralty to Chai Wan on 31 May 1985.

Design
Along with 36 other stations on the Kwun Tong, Tsuen Wan, and Island Lines, Causeway Bay was designed by then-chief architect Roland Paoletti, who would later go on to design the Jubilee Line extension of the London Underground. Paoletti elected for each station to feature its own colour scheme and walls painted in calligraphyCauseway Bay's station colour is purple.

Services
The station is situated between Wan Chai and Tin Hau stations on the. The typical off-peak service is 17 trains per hour in both directions, which is a train every 3–6 minutes.

Station layout
The platforms of Causeway Bay station are constructed in a stacked arrangement, with platform 1 above platform 2.
