Speed limit of KPE to be raised to 80kmh
THE speed limit on Kallang-Paya Lebar Expressway (KPE) will be raised from 70kmh to 80kmh, to be in line with that of Marina Coastal Expressway (MCE).
The new speed limit will apply from Dec 29, the day the MCE opens, said the Land Transport Authority (LTA) yesterday.
The upcoming MCE will connect Ayer-Rajah Expressway in the west to East Coast Parkway and the KPE in the east.
However, the speed limit at one section of the KPE will remain at 70kmh due to a tight bend located there.
This section is near the Upper Paya Lebar Road exit for motorists heading north, and the Airport Road entrance for south-bound motorists.
LTA said that the KPE's speed limit of 70kmh, set when it opened in 2008, was because of tight bends along the expressway.
There were also considerations that motorists may not be familiar with driving in a long-tunnel environment.
LTA has said that it will implement additional safety measures along the tight bends, such as adding reflective strips on tunnel walls and bend-alignment lane markings.
Associate Professor Chin Hoong Choor from the Department of Civil and Environmental Engineering at the National University of Singapore said that when speed limits are raised on roads, the differences in speeds between vehicles will increase, and that motorists will need to exercise more caution.
"The heavier the traffic and the more varied it is, the higher the chances of collision, all things being equal," he noted.
Real-estate agent Alfred Yap, 44, felt that the new speed limit on the KPE is safe. "My concern is about heavy vehicles that tend to speed in the tunnel," he said.
