A new dual-layered transport corridor for Singapore
The multibillion-dollar construction of a dual-layered transport corridor across the island, including a 12.5km tunnel, has challenged our engineers like few other projects – but we are coming through with ingenious solutions that break new ground in more ways than one

The 21.5km corridor will relieve congestion through a mix of tunnel and elevated viaduct, while providing dedicated bus lanes, cycling and pedestrian paths at the street-level. Its first 12.5km route comprises a stacked box tunnel that dives beneath the majestic modern skyscrapers and traditional street markets in the central business district (CBD). Emerging north of the city centre, vehicles will continue their journey at surface level before the route transitions into 9km of elevated viaduct.
World leading innovation on a transit project
Challenging ground conditions and proximity to existing structures have made our team’s decades of expertise invaluable in finding innovative solutions on the North-South Corridor (NSC) project. A dual-layered transport corridor, it is planned to run from residential areas in the north of Singapore into the city centre.
