Winter Road Maintenance Plan of Operations for roads maintained by Lincoln County Road Departments

Lincoln County has adopted the following plan of operations for winter maintence on County-maintained roads:

During storms, snow may be allowed to accumulate up to six inches or until the next scheduled shift before plowing and sanding begins.

Major hills, school bus routes, mail routes, main roads, and intersections will always be given first priority. After storms, sand, salt, or liquid de-icer will be applied a deemed necessary by the District Road Foreman to hills, curves, and intersections for added traction. Sanding in the Libby District is done under Air Quality Guidelines.

Lincoln County only maintains county roads and those roads specified in an agreement with the U.S.F.S. Private roads and other Forest Service roads will not be maintained by the county. In addition, no sanding is done on Forest Service roads that are maintained by the county.

Lincoln County will not be responsible for the following:

  • Snow berms in driveways
  • Damage to mailboxes
  • Damage to fences
  • Damage to vehicles parked in the road right-of-way.
  • Damage to sprinklers in the right-of-way.


You can help improve driving conditions and lessen risk in winter conditions by observing the following:

  • Any vehicle used in winter driving conditions should be equipped with winter tires or traction devices, including studded or sipped tires and tire chains. All-season tires may not be adequate for safe driving.
  • Do not park on the road right-of-way, Vehicles parked on the right-of-way are subject to impoundment and a $50.00 fine for each offence, create a driving hazard and prevent us from plowing the full width of the roadway for optimum safety.
  • Don not plow snow from onto county roads.
  • Do not follow snow removal equipment closer than 50 ft.


Drivers should always be aware of current road conditions and be cautious during driving situations. We will do our best to keep roads as safe as possible. If you are aware of any areas that become unsafe, please contact the road department in your area.

Did You Know?
“Subnivean” Zone

Have you ever heard of the “subnivean” zone? It’s the area between the surface of the ground and the bottom of the snowpack that’s home to mice, voles and shrews during the winter.

  • Air gets trapped
    between snowflakes as they land creating insultation
  • Heat from the
    animals below gets trapped forming an igloo effect
  • It takes about 6″ of snow to create a sturdy roof for their homes
  • At 8″ of snow, the temperature stabilizes at 32 degrees within the zone
