The Lincoln County Road Department maintains 87 bridges for vehicular traffic. In addition to the 87 vehicular bridges, the biennial inspection program inspects one non-vehicular covered bridge, and three public road bridges (Johnson Street, New Bridge Road, Aldersprings Road). 

The county's bridges (including two historic covered bridges) open to vehicular traffic are constructed of timber, concrete and steel. Bridge spans range from approximately 10 feet to 470 feet.
