Four people were killed and at least 12 were injured in a crash involving two tractor trailers and at least seven cars on Monday, August 5, 2019.
Over the last 25 years, engineer Robin Borgia has been following numerous road accidents along a busy stretch of 440 Laval highway.
But the fiery crash he witnessed when he looked out of his office window on Monday was the worst thing ever.
"I saw a car, caught under the tractor trailer, and another big truck behind it," said Borgia, who works for an expert consulting firm d & # 39; ACE, a consulting firm.
One car was trapped under the first truck and another was left on the right side of the truck.
"The tires started to explode and the fire became very intense," Borgia said in an interview. "We wondered if it was a propane tank as well. It all happened very quickly. "
As flames emerged from the captured vehicle and the back of the tractor trailer, a truck driver jumped into his cab and pulled away to try to release the burning vehicle, Borgia said.
When some of the first police officers and a paramedic arrived, they had to jump over a fence near the scene to reach the injured motorists, he said. Eventually, the truck driver turned to the fence to create a gap wide enough for the first responders to pass.
Sûreté du Québec are asking motorists who witnessed the fiery collision of Highway 440 in Laval on Monday afternoon to contact them.
Four people were killed and 15 were injured in the crash near Industrial Boulevard, which involved two tractor trailers and at least seven vehicles.
One of the heavy trucks caught fire after hitting a car in front of it and overturned. The flames spread to some of the other vehicles and black clouds of smoke could be seen for several kilometers.
Several people were rushed to the hospital, including the first responders to be beaten by smoke.
A dense cloud of smoke swirled in the air and the highway was still closed to traffic on Monday evening, causing traffic jams for several kilometers.
Borgia colleague Mario Lehoux said that configuring the section of Route 440 near the exit of Route 15 is problematic and dated.
At rush hour, cars are often backed up to 400 meters to exit Exit 15 on the north. The growth of Laval Industrial Park and the increased population density north of Montreal mean that the exit lane and the service route are often supported.
"The cars zip in front of the trucks to take the exit and they merge too fast," he said. "They are disappointed because they have to wait so long to get out."
Quebec Transport Minister Francois Bonardel has extended his condolences to the families affected by the accident.
Anyone with information about the crash should call the Provincial Police at 1-800-659-4264.
