It was a very close call for motorists after a truck lost its load on a ramp off the eastbound Metropolitain and showered engine parts down onto the westbound lanes of the Met.
The tractor trailer was carrying heavy truck parts when it tipped over on the ramp to Autoroute 15 northbound from the 40 east at 2 o'clock this morning.
The SQ says the truck parts likely shifted in the trailer, causing it to tip over, because the driver wasn't speeding.
One of those truck parts flew off the ramp and down onto the westbound lanes of the 40.
It damaged a car but no one was hurt.
The SQ says it could take until 8 AM to clear the accident.
The driver of the tractor trailer is being treated for shock.
