SINGAPORE - Water pipe leaks in the Jurong area has shoved up part of the road surface on the Ayer Rajah Expressway (AYE) .
A part of the expressway near Corporation Road about the size of a bus is now tilted up to about 1 metre at its highest point, Lianhe Wanbao reported on Sunday (April 9)
National water agency PUB said it was informed of water flowing over a turf area next to the AYE into a drain on March 29.
Two nearby pipelines were found to be leaking and they were isolated on the same day.
"These pipelines convey Industrial Water and NEWater, which are used by non-domestic customers mainly for cooling and process purposes," PUB said. "Water supply to our customers is not affected."
PUB said that "ground upheaval" was observed at the bus bay access along AYE.
"The affected section of the bus bay ingress has been cordoned off as a safety precaution," it said.
Other motorists along AYE are not affected, but the Land Transport Authority (LTA) is monitoring bus routes along this stretch to mitigate any inconvenience to bus commuters.
The cause of the upheaval and leaks is still unknown.
"LTA and PUB are jointly investigating the ground upheaval. The cause of the pipe leaks is also under investigation," PUB said.
Clearance work is being carried out at the site where the pipes are located so that PUB can proceed with repair work.
