The highway has been cleared outside of Regina after a serious 2-vehicle head-on collision Thursday.
Southey RCMP responded to the scene about 8 kilometers north of Regina, on Highway 6.
It involved a north-bound semi and a south-bound pickup truck.
The 35-year old pickup driver from Regina was airlifted to a Regina hospital with serious injuries.
Diesel fuel and hydraulic fluid spilled onto the highway and into the ditch, but is in the process of being cleaned up.
Traffic could be slow through the area Friday morning.
