The Hamilton County Highway Department is responsible for all roads, bridges, and small structures (less than 20-foot span) within Hamilton County which are not state highways and which are not within the corporate limits of a city or town. We are also responsible for bridges which have a span of 20 or more feet on all roads in Hamilton County which are not state highways. 

Hamilton County has 9 townships with approximately 600 miles of unincorporated roadway and rights-of-way, 300 bridges, and over 600 small structures to maintain. The Hamilton County Highway Department strives for safe, accessible and efficient roadways, and continues to work to improve the transportation infrastructure for the citizens of Hamilton County.
