Motorists are being advised of traffic delays on Highway 22 following a crash. 

RCMP got a call just before 10 a.m. about the collision involving a van and a semi-tractor and trailer on Hwy 22, north of Range Road 280 and south of Range Road 281. 

Cochrane RCMP say the combination of weather and poor road conditions led to the semi-tractor and trailer losing control on the road to avoid a collision with the van. 

But as a result the tractor trailer then slid into the ditch and rolled. 

Fire crews, EMS and RCMP are on the scene.

Traffic is down to one lane and drivers are being advised of delays while the scene is being cleaned up.

Motorists are being asked to avoid the area for the next several hours. 

There's no word on any injuries.
