Traffic is backed up on the Trans-Canada Highway just outside of Winnipeg Tuesday evening.

Witnesses tell CHVN that a collision on Highway 1 at the East Perimeter Highway is to blame.

There is no word on how many vehicles are involved or injuries at this time.

Westbound traffic is currently at a standstill as emergency crews respond.

Light snow and just below freezing temperatures have caused slick conditions on highways throughout the region.

This is a developing story. More to come.
