Road network

Optimising road network for growing travel demands.

Our more recent and upcoming road building programmes are focused on newly developed areas. 

For example, the expansion of the Kallang-Paya Lebar Expressway and the Tampines Expressway (KPE/TPE) Interchange, completed at the end of 2020, was to address the traffic needs of residents of Punggol town.

Ongoing projects include:

  • The 21.5km North-South Corridor (NSC) connecting the northern region to the city centre, will be completed in phases from 2027. It will support new developments in the northern region, and alleviate congestion along the Central Expressway (CTE) and major arterial roads. With more traffic diverted to NSC’s underground tunnel and viaduct, surface streets equivalent to about 30 football fields will be freed up and repurposed to prioritise walking, cycling, public transport, and community spaces.
