Road and Bridge Department

The Bonner County Road and Bridge Department is responsible for the maintenance and construction of 679 miles of County roads. 286 miles of hard surface and 393 miles of gravel roads are plowed and sanded during winter season.  The 3 road districts apply road stabilization material (dust abatement) to over 200 miles of gravel road and chip seal 50 miles of pavement each year.

Our Goals

The Road and Bridge Department is committed to serving the residents and visitors of the County to the best of their ability and resources. From the office personnel to the crew members in the field, our goal is to make the roads of Bonner County safe and acceptable for all who travel upon them.

Road Department crews have been grading and improving right of way drainage and sight distances this spring and are in the process of converting our equipment to summer mode. With a worse than normal spring breakup, weight limits are posted on all County maintained roads with a few in the Sagle and Cocolalla area that are closed to all hauling until further notice as of April 3, 2019.
