Two major road infrastructure projects, scheduled to be completed in 2019, will offer motorists a smoother ride along a section of the Tampines Expressway (TPE) and in the Bukit Timah area.
The Land Transport Authority revealed details of the projects to The Straits Times yesterday after calling tenders for them last month.
A new one-way viaduct will be built along the TPE to offer motorists a direct connection to the westbound Pan-Island Expressway (PIE) and also to Upper Changi Road East.
The approximately 1.5km viaduct will "alleviate the congestion currently experienced at this stretch of TPE", an LTA spokesman said. Existing junctions linking Upper Changi Road East, Upper Changi Road North, PIE and TPE will also be improved.
The tender for this project will close in May.
Separately, the road network around Jalan Anak Bukit will be improved with the construction of a 400m city-bound, three-lane carriageway between Jalan Jurong Kechil and Clementi Road.
This will provide motorists with an alternative city route. For example, those coming from Toh Yi will be able to use this road to go to Dunearn Road, instead of having to make the circuitous route using Jalan Anak Bukit.
This will help to distribute traffic away from the busy Jalan Anak Bukit and Jalan Jurong Kechil intersection.
As part of the project, the Jalan Anak Bukit slip road leading to the PIE will be widened. Also, the stretch of Jalan Jurong Kechil between Toh Tuck Road and Upper Bukit Timah Road will be upgraded from two lanes to three in both directions.
LTA said the improvements will also benefit other commuters, as bus services in the area will be able to operate more efficiently.
Cycle paths along Jalan Jurong Kechil, Jalan Anak Bukit and Upper Bukit Timah Road will be also built. These will allow connections to future paths under the National Cycling Plan to form an islandwide off-road cycling network of over 700km.
The tender for this project will close this month.
National University of Singapore transport expert Lee Der Horng said the new carriageway will help ease the "bottleneck" at the Jalan Anak Bukit and Jalan Jurong Kechil junction.
Of the new TPE viaduct, he said: "This will enhance the connectivity between expressways. You do not need to get down from the expressway, use the local street and get back onto the highway."
