Located beneath two of the busiest streets on Hong Kong Island and alongside the foundations of some of the city’s most prestigious buildings, precision was essential in the design and construction of both stations.

The Central site adopted a top-down method allowing excavation to take place below ground, while building works began above. The site also required special excavation techniques to avoid damage to adjacent buildings.

More than 30 years on, the stations remain essential arteries in Hong Kong’s busy MTR, transporting generations of commuters from their homes to their work places.
