Snow plowing and ice control guidelines for state maintained highways

To tame winter storms, Wisconsin's county highway departments plow and provide ice control on all state and US-numbered highways, and the Interstate system. This arrangement is unique to Wisconsin and for more than 85 years has provided efficient and cost effective winter service for all Wisconsinites.

The following explanations and links are intended to provide you with insight into Wisconsin's snowplowing guidelines.

  • The 18-24 hour service page contains a map and text listing that shows which highways are maintained for 18 or 24 hours a day during a winter storm event.

  • The passable roadways page details the level of effort, during a winter storm event, that different categories of highways receive.

  • The snow plowing priorities page provides information about what order the counties typically follow when plowing roadways.

  • The snow plowing brochure page shows the winter brochure that was created and distributed when the plowing guidelines were revised in the fall of 2002. The brochure is no longer in print but the map showing the roadway categories is updated every winter and available for printing off the Web page.

  • The frequently asked questions page give answers to many questions about the Wisconsin's snowplowing and salt usage.

  • The winter maintenance facts sheet gives some statistics on Wisconsin's weather and winter maintenance.
