The 21.5km North-South Corridor , is meant to enhance communication from , Singapore’s northwestern territory to the city, serving cities such as Sembawang, Yishun, Ang Mo Kio, Toa Payoh, Novena and Rochor.  ,

The landscape architecture strong Henning Larsen developed ideas for the exterior streets along the , North-South Corridor.
The company and its associates have been appointed , Master Plan Consultant for the exterior streets, LTA announced on Tuesday, after reviewing ideas from , 25 various local and international architecture teams.
According to LTA,  , Henning Larsen had envisioned , the , North-South Corridor , as a horizontal hall featuring four different personality segments- a 6km Community-Industrial section, a 7km Ecological Loop, a 5km People’s Wellness Corridor, as well as a 3.5km Cultural-Heritage section.
More than 20 public space nodes will be lining these four segments, which “represent the distinctive characteristics of the adjacent neighbourhoods and destinations,” the agency said.
In Ang Mo Kio, for instance, one idea is to create an area that , features nature-based public spaces, cycling paths, footpaths and play areas lined with greenery. These would connect the corridor to neighbourhoods and places such as , Bishan-Ang Mo Kio Park.
Meanwhile, the northern stretch of the corridor could include spaces for a playground, art installations and cycling beneath the corridor’s viaduct at Gambas Avenue.  ,
