Road & Bridge

About

The Boundary County Road and Bridge Department maintains over 355 miles of public roadway and 40 bridges in Boundary County. Of this, 150+ miles are hard surfaced (paved) and the remainder are graveled. By comparison, there are 78 miles of road maintained by the Idaho Department of Transportation, including US 95, Highway 1 and US 2.

Our maintenance equipment travels up to forty miles on state highways per round trip to access many segments of our county road system. Sand trucks often travel over 200 state highway miles per day to service county roads for winter maintenance. Each time our graders go out to do routine maintenance, they are each faced with approximately 45 miles of road to cut and refill and must make an average of six passes to complete the work, traveling over 300 miles at very low speed. Optimal grading conditions are during the drying period after a rainfall, when the new surface can be compacted. Grading during dry or wet periods usually results in repairs with a short life expectancy, just one of many of the challenges faced by the department in maintaining a large are with limited resources.
