Highway Department

The Marathon County Highway Department operates the highway system under its jurisdiction to provide a safe and convenient means for the vehicular transportation of people and goods.

The department oversees the maintenance of over 600 miles of the county trunk highway system and annually contracts with the Wisconsin Department of Transportation (WisDOT) to maintain an additional 874 lane miles of state and federal highway system roads.

The Highway Department also provides technical assistance, financial aid, and various services to other local units of government, including the Metropolitan Planning Organization (MPO). These services are critical to maintaining a safe, convenient, and efficient transportation system serving communities, residents, and businesses throughout Marathon County.

The policymaking body for the Highway Department is the Infrastructure Committee. The committee consists of seven county board members elected for two-year terms by the County Board of Supervisors. The powers and duties of the Highway Committee are defined in s. 83.015, Wis. Stats.

The administration and implementation of the departmental policies is the responsibility of the Highway Commissioner with assistance from the administrative staff. The Highway Commissioner reports to the Highway Committee and is also charged with certain duties as directed by s. 83.01, Wis. Stats.
