CHONGQING - The municipality of Chongqing in southwest China is extending a subway station to more than 94 meters underground, an equivalent of 31 storeys below ground, which will make China's deepest station.
Hongtudi station, which opened on Line 6 years ago, was dubbed Chongqing's deepest station at 60 meters below ground. Now, the station is being extended deeper to connect with Line 10, a new metro line to be opened by the end of 2017.
Chongqing is known as a "mountain city" in China. Because of the hilly terrain and to avoid damaging air-raid shelters and pile foundation of street buildings, the station has to be built deep underground.
It currently takes commuters more than three minutes to get from the platform of Line 6 to the street by taking elevators, longer if they wish to climb 354 steps.
The station's 32 elevators will be increased to 91 when it becomes a transfer station.
