Speed limit on KPE to be raised soon
THE speed limit for the Kallang-Paya Lebar Expressway (KPE) is set to go up from 70kmh to 80kmh as early as next month - six years after the largely underground highway opened.
The Straits Times understands that the limit will be revised to be in line with the limit for the Marina Coastal Expressway (MCE), which will open at the end of the year.
The KPE joins the MCE, which also joins the Ayer Rajah Expressway.
However, certain stretches with sharper curvatures may retain the 70kmh limit.
Speed limits on other expressways are mostly 90kmh.
Associate Professor Wong Yiik Diew, who teaches road transportation at Nanyang Technological University, said the revision may be to align the speed limits of the KPE and MCE. The two highways "may appear disjointed if there were two different speed limits", he said.
The KPE's speed limit is enforced largely by laser cameras, which detected 29,404 speeding violations last year. The number represented 12 per cent of speeding offences islandwide over the period - despite the KPE tunnels making up only 0.5 per cent of Singapore's road network.
Regular users of the KPE welcomed the new speed limit, saying traffic in the tunnels is often not heavy, and does not warrant such a conservative cap.
Bank officer Rongwei Ng, 30, said: "It should be raised to at least 80kmh, because the traffic is too slow for off-peak-hour usage."
