SINGAPORE \u2013 The 21.5km highway linking the northern towns to the city will be delayed by two years due to unexpectedly difficult ground conditions that require more complex construction work.<\/p>\n
The North-South Corridor (NSC) viaduct, which runs from Admiralty West to Lentor Avenue, will now open in stages from 2029, instead of 2027.<\/p>\n
The tunnel section from Lentor Avenue to East Coast Parkway will open in phases from 2031 instead of 2029, the Land Transport Authority (LTA) said on Sept 17.<\/p>\n
From 2028, roads, footpaths and nearby areas affected by construction works will open in stages, and noise barriers will start coming down.<\/p>\n
Pedestrian overhead bridges affected by the construction of the tunnel section will go back up from 2029.<\/p>\n
With more than 90 per cent of the foundation works for the 8.8km viaduct and the 12.3km tunnel completed, works along the viaduct will focus on installing above-ground structures like columns, crossheads and viaduct segments.<\/p>\n
As for the tunnel, most of the work will carry on underground from 2027, and help ease disruption to surrounding roads, LTA said.<\/p>\n
