Airdrie Rural RCMP are investigating a collision between a semi and a parked pickup that happened yesterday (May 20) afternoon, sending two people to hospital.

Police say the semi was southbound on QEii and hit the pickup which was parked on the east side of the southbound lanes.  The semi then veered off the highway into the west ditch and went through a cement fence, stopping just short of some people's yards.  The incident occured just before the Yankee Valley Boulevard turn off.  

A man and a woman were in the pickup and had to be taken to hospital in non-life threatening condition.  The driver of the semi was apparently unhurt.

Traffic on the QEII was backed up to north of the Airdrie city limits following the crash.

RCMP continue to investigate the cause.
