Quarry Bay (Chinese: 鰂魚涌) is an area beneath Mount Parker in the Eastern District of Hong Kong Island, in Hong Kong. The western portion of the area was also formerly known as Lai Chi (麗池). Traditionally being an industrial and residential area, the number of commercial buildings in this district has increased over the past two decades.
During Colonial Hong Kong times, the Hakka stonemasons settled in the area after the British arrival.
The area was a bay where quarried rocks from the hillside for construction or building roads were transported by ship. The Chinese name Tsak Yue Chung (鰂魚涌) reveals that it was a small stream where crucian carp (鰂魚) could be found back in the 19th century. The English name was Arrow Fish Creek. The original bay has disappeared since land reclamation had been taken place, and was about 700m from the current coastline.
The eastern part of Quarry Bay, namely Quarry Point, was largely owned by Swire and therefore many places and facilities are named after the company's Chinese name, Taikoo. The river originally flowed into the bay, however it was shut off from the sea with the construction of the Tai Koo Reservoir to supply fresh water to the Taikoo Dockyard, the Taikoo Sugar factory at Tong Chong Street (糖廠街), and later the Swire Coca-Cola factory at Greig Road (基利路) and Yau Man Street (佑民街). The upper course of the river was converted into a cement-paved catchwater, and the lower course is the present-day Quarry Bay Street (鰂魚涌街), with the original estuary near the Quarry Bay Street - King's Road junction.
Quarry Bay Station is an underground station on the MTR Island and Tseung Kwan O lines in Quarry Bay on Hong Kong Island. The station livery is teal green.
As with all stations on the Island Line, Quarry Bay is located on the northern shore of Hong Kong Island. Platforms 1 and 2 are built beneath King's Road to Pak Fuk Road. Platforms 3 and 4 are built beneath King's Road to the south of Model Housing Estate.
In the course of constructing Quarry Bay Station, with the initial two platforms, 70,000 cubic metres of rock was excavated and 28,000 cubic metres of concrete was poured. The station opened as part of the second phase of the Island Line on 31 May 1985. The station was expanded in 1989 with the addition of Platforms 3 and 4, which served as the terminus of Kwun Tong Line upon the opening of the Eastern Harbour Crossing.
The station was badly congested in the mid-1990s. The station had a capacity of 30,000 people per hour, and was "close to saturation". Contingency plans were developed to evacuate trains ahead of Quarry Bay to avoid overcrowding, while construction options were planned to alleviate the problem permanently. On 27 September 2001, the Quarry Bay Congestion Relief Works was completed, extending the Kwun Tong Line to North Point Station and providing an easier and more spacious interchange there for Central-bound passengers. On 4 August 2002, the Kwun Tong Line platforms began serving the newly formed Tseung Kwan O Line instead.
