This varies. If there is a lot of snow, or if the snow is heavy and moist, or if there is a strong wind, it can take longer to move the snow and fight drifts – and can take several days to complete road clearing.
Depending on road conditions, it can take up to 72 hours for a grader to complete its entire beat after it stops snowing as per Gravel Road Maintenance Requirements Policy. However, strong winds can close a road before the 72 hours have lapsed.
Timing can be severely affected by the amount of snow, temperature, continuing bad weather such as wind causing drifts or by poor visibility.
