The stretch of the Yellowhead highway between Vermilion and Mannville will be getting an upgrade this week. Crews will be doing chip sealing on the highway, in order to preserve the road. Public Affairs Officer with Alberta Transportation Jamie Friesen says traffic will go down to one lane for east bound traffic and motorists can expect delays. Friesen also asks drivers to be careful as they pass the road crews, and add extra time to their commute. The chip sealing will last until Friday.
