Two men are dead after they were struck by a tractor trailer on Highway 400 north of Barrie early Friday morning, police said.

The incident occurred between Mount St. Louis Road and Moonstone Road in Oro-Medonte Township at about 6 a.m.

Police said a broken-down transport truck was being hooked up to a tow truck when another transport struck the victims on the side of the road.

The two men were standing near the rear wheels of the disabled tractor trailer when they were hit by the southbound truck.

Police said the truck continued down the road a short distance and came to a stop along the shoulder of the highway.

Both victims are from out of province but their identification is not being released at this time until next of kin have been notified.

Highway 400 was reopened at about 4 p.m. on Friday.

There is an ongoing investigation by Barrie OPP, the Central Region Technical Traffic Collision Investigation Unit, the Central Region Forensic Identification Unit, the OPP Aviation Unit and the Oro-Medonte Township Fire Service.
