Singapore
- Extensive underground networks exist around most major stations of the Mass Rapid Transit, such as the one at the Raffles Place MRT Station with direct underground connections to 19 buildings in the busy Raffles Place area. Expanding the network is the first phase of a new subterranean network linking the station to the up-coming One Raffles Quay development and with provisions to extend it into the Marina Bay new downtown extension for a complex underground pedestrian network across the entire downtown area.
- The CityLink Mall offers over 60,000 square feet (5,600 m2) of underground retail space and connects the City Hall MRT Station with Suntec City, the Esplanade - Theatres on the Bay, and other developments in the Marina Centre area. It is also linked to the Esplanade MRT Station on the Circle MRT Line.
- The Orchard Road shopping belt is connected by underground linkways often with commercial space, particularly around the three MRT stations serving the district, namely Orchard, Somerset, and Dhoby Ghaut . Plans are in place to link all buildings along the road into a continuous underground network on both sides of the over four kilometre long road.
