The Manitowoc County Highway Department takes great pride in the quality service in which we deliver to the citizens of Manitowoc County and we strive to address any safety issues and environmental concerns.  Our purpose is to perform the construction of and maintain the county trunk highway system which consists of 287 miles.  We also provide excellent quality, cost-effective roadway maintenance and construction services to the State of Wisconsin which total an additional 136 miles of highway and assist the local municipalities under agreements.  We have the responsibility of these 914 lane miles, not including the cities, towns and villages to effectively perform the maintenance and offer fast response time throughout our 594 square mile county as we operate from five separate facilities which include our Manitowoc location, Mishicot, Reedsville, St. Nazianz and Cleveland.
