SINGAPORE - Motorists were blocked off from a stretch of road along Jurong West Avenue 4 when a big tree was uprooted early Sunday (June 19) morning.

It was not clear what caused the tree, which was located near Block 704, to fall.

Teacher Melvin Koh, 32, said he was watching television at home in the opposite block at around 2.30am when he heard loud cracking noises and looked out of his window to investigate.

"The tree had fallen across the entire road in both directions. A taxi had to reverse and seek an alternative route," Mr Koh added.

No injuries were reported.

A Singapore Civil Defence Force (SCDF) spokesman said it dispatched a fire engine and a support vehicle to the scene.

"SCDF officers assisted in cutting the fallen tree before handing the operation over to the National Parks Board (NParks)," a spokesman said.

The Land Transport Authority first tweeted about the incident at 4.02am to warn motorists of an obstacle.

It later tweeted at 6.47am to avoid the right lane.

A video of the incident, which showed SCDF officers cleaning the road with water hoses, was uploaded by Facebook user Jackie Chia at around 5am.

Mr Chia later posted a photo at around 8.10am.

Tree branches were seen strewn by the side of the road and on the road divider while workers cleared up the debris.

Facebook user Rogger Yap also shared photos of the fallen tree and said both sides of the road had to be closed.
