The new Hillview flyover in Upper Bukit Timah Road will open this Sunday.
Motorists going to Woodlands from the city, or vice-versa, will be able to use the dual two-lane flyover to bypass a stretch of Upper Bukit Timah Road between Chestnut Drive and Jalan Asas.
The flyover provides an alternative route that will redistribute traffic from existing ground-level junctions at Dairy Farm Road and Hillview Road, the Land Transport Authority (LTA) said yesterday.
Construction for the 700m-long flyover started in the second half of 2011. Motorists can start using it from 8am on Dec 27.
The LTA has advised motorists heading towards Dairy Farm Road, Hillview Road and Jalan Asas to continue to use the ground-level roads, and not the flyover, to reach their destinations.
The Hillview flyover is the second one to be completed along the corridor this year.
In April, the Bukit Panjang flyover was opened along a stretch of Upper Bukit Timah Road and Woodlands Road.
The viaduct allows motorists to bypass the intersection of Choa Chu Kang Road, Upper Bukit Timah Road, Woodlands Road and Bukit Panjang Road .
The two flyovers are part of a larger infrastructure project, which also includes widening parts of Upper Bukit Timah Road and Woodlands Road to improve overall traffic flow in the corridor.
"With the enhancement of this key arterial road corridor serving the north-western part of Singapore, motorists travelling to and from Bukit Panjang and Choa Chu Kang residential estates, as well as the Kranji and Mandai industrial estates, will enjoy a better transport experience," the LTA said.
Mr Balasupramaniam, 69, a retiree, welcomes the new flyover. He said: "During the peak hours, the traffic along Upper Bukit Timah Road can be quite congested."
He added that motorists heading to Woodlands would enjoy a faster drive with the flyover, as they do not have to mix with traffic that is turning into the condominiums in the area, such as along Hillview Road.
