Several people are injured, at least one seriously, after at least 70 vehicles were involved in a pile-up on Highway 40 East, near Yamachiche in Mauricie, on Saturday afternoon, according to Quebec's transport minister.
As of 3:40 p.m., the highway remains closed near kilometre 174 as police try to clear the road. Some 100 vehicles are waiting for the road to reopen, which should take place within two to three hours, said François Bonnardel.
Shortly before 1 p.m., police were called to a multi-vehicle collision between kilometre 175 and 176, west of Trois-Rivières, according to a release from the Sûreté du Québec (SQ).
Police said several people were injured, with one suffering more serious injuries. Police did not specify the number of injuries.
The SQ said the collision may have begun when a heavy truck jackknifed. Harsh road conditions may have also played a role in the crash.
Officers, firefighters, paramedics and staff from the Ministry of Transport intervened on site, according to police. Buses were dispatched to evacuate motorists.
"It should be noted that all those involved were evacuated and taken care of by the responders," the SQ release reads.
Earlier in the day, the SQ warned motorists on Twitter about road conditions made difficult by snow falling in southern Quebec.
