SINGAPORE - An overturned tipper truck and an oil spill resulted in heavy traffic along Upper Thomson Road on Tuesday (Sept 6) morning.
The police said in response to media queries that it received a call around 4.17am about an accident along Upper Thomson Road.
The Straits Times understands that a tipper truck skidded and overturned in the early morning. The oil spill was the result of its fuel tank leaking from the accident.
When contacted, the Singapore Civil Defence Force (SCDF) said it was alerted to the accident around 4.19am and dispatched an ambulance to the scene. But no injuries were reported.
The National Environment Agency (NEA) said that it was told of the spillage at about 4.35am. Its service provider was on site at 5.15am to assist the SCDF and the Land Transport Authority (LTA) in the clean-up.
The company that the truck belongs to also assisted in the clean-up, a NEA spokesman said. "Our service provider stood down at about 12.15pm when its cleaning services were no longer needed."
In a Facebook post at 7.11am, police said lanes at the junction of Upper Thomson Road and Ang Mo Kio Avenue 1 towards Sembawang Road, as well as the road at the junction of Upper Thomson Road and Jalan Leban, were closed.
Motorists were told to expect heavy traffic and advised to find alternative routes.
In an update at about 9am, police said the lanes have reopened.
The lane closure announcement came after the initial closure of Upper Thomson Road after Yio Chu Kang Road, which the Land Transport Authority tweeted at 4.34am.
Police investigations are ongoing.
