Six Year Highway Improvement Program: 2017-2022

Wisconsin's highway network

Wisconsin has 115,371 miles of public roads, from Interstate freeways to city and village streets. This highway improvement program covers only the 11,746-mile state highway system which is administered and maintained by the Wisconsin Department of Transportation (WisDOT). The other 103,625 miles are improved and maintained by the cities, towns, counties and villages in which they are located.

The state highway system consists of 875 miles of Interstate freeways and 10,871 miles of state and US-marked highways. While the 11,746 miles of state highways represent only 10.2% of all public road mileage in Wisconsin, they carry over 36 billion vehicle miles of travel a year, or about 58.3 % of the total annual statewide highway travel.

Each wisely invested dollar returns benefits in terms of time savings, fewer accidents and decreased vehicle operating costs. Poor roads mean more accidents and deaths, higher insurance costs, more wear and tear on vehicles, more time on the road and less efficient and competitive commerce.
