A portion of Hwy 2 near the turnoff leading into Red Deer was shut down for more than five hours on Saturday due to a propane leak caused from a two-vehicle collision.
At about 1:30 p.m., Red Deer Emergency Services and the RCMP Integrated Traffic Unit responded to a serious collision just north of Gasoline Alley.
The collision, which had completely blocked the northbound lanes of the highway, occurred on a curve under the Gaetz Avenue overpass.
Police say two vehicles were negotiating a curve and collided.
A truck pulling industrial equipment on a trailer slammed into the guard rail.
The trailer separated and rolled while the truck went off the road and became partially submerged in a slough.
The driver of the second vehicle, a sport utility vehicle, lost control and rolled.
It slid on its roof for several metres.
The driver, who was wearing his seatbelt, was taken to hospital with minor injuries and later released.
The other driver was not injured.
Fire-medics arrived to find a propane leak from a mid-sized tank being transported on the damaged trailer.
The propane leak and subsequent clean-up forced the northbound lanes to be closed for more than five hours while traffic was diverted through Red Deer.
Police continue to investigate the possibility of mechanical failure as a contributing cause but say they have ruled out speed and alcohol as factors.
