The Road Commission organizes snow plowing operations to service the most heavily traveled roadways first during and after a winter storm. Approximately 370 miles of County Primary Roads, and certain high traffic local roads in urban areas, are plowed and/or salted first. After these roads are passable, crews move on to clear local paved roads throughout the county. Typically, local subdivision streets and rural gravel roads are cleared after all other higher traffic roads, within several days of the storm. Although our crews may begin plowing/salting several hours before the morning peak traffic, and continue operations into the night, extended winter storms or continuing winds may require crews to continually plow the main high traffic roads, which prevents them from reaching subdivision streets and rural gravel roads for several days.
