Ontario Provincial Police say two workers working on behalf of the Ontario Ministry of Transportation (MTO) were seriously injured after being struck by a driver in Bradford, Ont., Sunday morning.
OPP say they were called to a collision on Highway 400 southbound and 5th Line at around 7 a.m.
Two workers who were standing outside of a "blocker truck" to divert traffic for a separate collision, were hit by a driver, according to police. OPP previously said the employees were MTO workers but later clarified the workers were employees of a company contracted to do work for MTO.
"A passenger vehicle entered into the road closure of a collision scene," OPP said in a post on X, formerly Twitter.
Officers say the vehicle struck one of the worker's trucks on scene.
Both workers were taken to a trauma centre with serious injuries. One worker was in stable condition Sunday afternoon, while the other was in life-threatening condition, OPP say. The driver and passenger in the other vehicle involved were also taken to a hospital with unknown injuries.
The highway stretch remains closed as police investigate. Police say it is not known at the time when it will reopen to traffic.
