The City of Grande Prairie classifies roads in three ways:
- Priority 1, 2, and 3
Each classification of road is maintained using a snow clearing method specific to the type of road.
City crews plow, windrow, sand, salt and remove snow from priority routes throughout the winter. This service is separate from Residential Snow Clearing. It is possible for a Priority 2 route to be in a residential area.
Priority 1 and 2 roads must be cleared first to ensure fire trucks, ambulances, other essential services, and the majority of the travelling public have a clear route on which to travel.
Major Arterials; 100 St, 84 Ave, 68 Ave, Resources Rd, Hwy 40 - Wapiti Road, etc., and primary access roads for Emergency Services.
Service Level - These routes will be plowed when snowfall accumulations exceed approximately 7.5cm and service will be initiated within 24 hours after the end of the snowfall event. The intent is to maintain the driving lane clear of compact snow.
