Hay Street: Woman in critical condition, major road shut after two cars plough into West Perth business

An elderly woman is fighting for life after two cars smashed into each other at a freeway off ramp, before ploughing into a business in West Perth.

Emergency services rushed to the scene after reports of a collision between a Star Track van and ute at the Mitchell Freeway off ramp, near Hay Street, about 7am on Monday.

The vehicles then left the road and hit the first floor of an office building on Hay Street.

One of the drivers, a woman aged in her 70s, sustained critical injuries.

A man aged in his 30s was also injured and was treated by paramedics at the scene.

No one from the business was hurt, with employees evacuated before first responders arrived.

Shocking images of the scene shows both vehicles completely mangled, with the ute sandwiched on top of the van.

Part of a bonnet can also be seen completely severed.

A crane was seen removing both vehicles from the wreckage about 10.30am.

The Star Track van was seen completely crumpled, with its mangled windows and doors hanging off the side of the car.

Witness Ben said he was walking to work when he heard a loud bang.

“As I was crossing the bridge … I turned around to see a car landing in the window of that building,” he said

“(It was) quite a loud sound … loud impact, and then the (sound of) the second impact of it hitting the building.

“I just (saw) the two cars that were stuck — one in the building, one underneath.”

Ben said he rushed over the scene to see if he could help and administer first aid.

“I went over to see if I could help the drivers … (there was) no response from either,” he said.

“I came around and went from the underside and got one of the drivers out from underneath, and just helped out and administered first aid.

“I basically got (a man) out of the vehicle … I helped him out of the vehicle because we could get access to his door.”

Department of Fire and Emergency Services incident controller Gareth Deeg described the incident as a “complex situation” and said officers would be on scene until about midday.

He said WA Police were still piecing together what happened in the moments before the collision.

“Major crash are now on scene, so they’ll reconstruct the incident and they’ll work out what’s happened,” he said.

“All we do know is that the two vehicles were coming off the freeway and they’re now where they are positioned in.

“It is a complex situation when vehicles leave the road and impact other structures, so this is going to be a drawn out process.”

Mr Deeg said the structural integrity of the office building had also been impacted.

“There is going to be some structural assessments that will need to continue to be done throughout the day,” he said.

“And with our with West Perth and Perth local governments, we’ll work together to make those areas safe.”

Hay Street has been closed westbound at George Street.

There is a heavy police presence, with major crash investigators scouring the scene.

Drivers are urged to seek an alternative route and exercise extreme caution.
