Description: The Expo MRT Station (CG1) was opened on 10 January 2001, and is part of the Singapore MRT Changi Airport Extension to the existing East West Line. It sports a space age architecture designed by world renowned architect Sir Norman Foster. The roof is clad in titanium (Ti), steel, and glass, and its design enabled the platform to be columns-free and invoking a sense of spaciousness. This design is also functional in that it handles human traffic which deviates significantly on a daily basis due to its proximity to the Singapore Expo, where human traffic is dependent on the timing of events held. The large space is thus needed to facilitate smooth traffic flow.
