Firemen are extricating the debris to reach the motorist and motorcyclists, believed to be pinned under the rubble, consisting mostly metal scaffolding and steel beams.
Bayan Baru MP Sim Tze Tzin, who was on the scene, said about a 30m-long span of the ramp was believed to have collapsed around 7pm, as work to install concrete boulders to strengthen the structure was ongoing.

"It's too early to say if there is any casualties.
"We also cannot confirm yet the cause of the accident," he said, adding that a full investigation would be carried out.
Many motorists have also stopped to look at the debris.
As of 9:30pm Thusrday night, fire department authorities have briefed Sim and Lim, saying a car was believed trapped under the rubble.
They are waiting for a larger crane so they can lift heavier pieces of rubble.
R. Thilasheni, 24, whose car's windscreen was shattered by a falling beam during the incident, was still in a state of shock.
"We were lucky to come out alive. We were only about three seconds away from when the ramp collapsed," she said.
She was travelling with her friend G. Gajashaantini, also 24.
She believed a motorcyclist was trapped under the rubble and said a beam fell onto a blue-coloured Myvi car in the incident.
The 24km-long bridge was set for completion next month.
