The North-South Corridor (NSC) is a multi-modal transportation corridor that will enhance connectivity from the northern region to the city, serving towns such as Sembawang, Yishun, Ang Mo Kio, Toa Payoh, Novena and Rochor. It will help to relieve traffic along Singapore’s north-south transportation axis and support new developments along the corridor.
Originally conceived as the North South Expressway (NSE), the project was reimagined to become the NSC in 2016 to enhance the Walk-Cycle-Ride (WCR) experience, and now comprises the NSC Expressway (Viaduct and Tunnel) and the NSC surface streets. With vehicular traffic diverted to the NSC viaduct and tunnel, surface streets can be used for wider footpaths, cycling paths, bus priority measures, as well as more communal and green spaces.
The NSC is expected to be completed in phases from 2027. We target to open the viaduct portion of the NSC from Admiralty Road West to Lentor Avenue in 2027; and the rest, comprising a road tunnel from Lentor Avenue to East Coast Parkway (ECP), in 2029. The surface streets will then be repurposed to prioritise walking, cycling, public transport, and community spaces.
The North South Corridor will serve Towns including Sembawang, Yishun, Ang Mo Kio, Toa Payoh, Novena, Rochor.
The North South Corridor, runnng 21.5km, will have dedicated bus and cycling lanes.
