Highway 1 is now open after members of the White Butte RCMP, Moose Jaw Combined Traffic Services and other emergency services responded to the scene of a double fatal collision on the westbound lanes of the Trans Canada Highway at the Belle Plaine turnoff Saturday.

Police say the collision is still under investigation, however preliminary examination has determined the collision involved a vehicle and a truck pulling an empty horse trailer.

Two people were pronounced dead at the scene, an adult man and woman who were both in the vehicle heading eastbound at the time of the collision.
