SINGAPORE - An oil spill resulting from an accident between a car and lorry held up motorists travelling along the East Coast Expressway (ECP) on Friday (May 27) morning.

The spill, which measured 2m by 10m, occurred before the ECP's Bayshore exit in the direction of Changi Airport.

A dark substance had been spotted on the road after the accident.

Two lanes on the expressway were closed as the Singapore Civil Defence Force (SCDF) dispatched two fire engines at 8am to assist with clean-up operations before handing the case over to the Traffic Police.

The Land Transport Authority first tweeted about the accident at 7.17am, and warned motorists of traffic congestion till the Siglap Road exit.

It also said to avoid lanes 1 and 2 on the expressway.

The Singapore Police Force (SPF) subsequently posted an update on its Facebook page, advising motorists to avoid the ECP and use alternative routes if possible.

A second update at 10.22am informed the public that all lanes on the expressway were open.

No injuries were reported and investigations are ongoing, said a police spokesman.
