Police say three men died in a fiery crash that closed the Trans-Canada Highway in Yoho National Park for 37 hours.
RCMP say the collision just west of the British Columbia-Alberta boundary happened just before 6:50 a-m Sunday.
The preliminary investigation suggests a westbound semi truck hauling cattle crossed over the centre line and hit an eastbound semi-truck hauling lumber.
All but one of the cows also died.
The highway reopened around 8 p-m last night.
