Effective today, frozen road declaration ends, Spring Thaw, Class II road restrictions take effect in southeast Wisconsin

March 13, 2014

Warmer weather results in changes for Zones 4 and 5

Due to warming weather, the Wisconsin Department of Transportation (WisDOT) has announced that effective today (Thursday, March 13 at 12:01 a.m.), the frozen road declaration ends and Spring Thaw and Class II road restrictions take effect for Zones 4 and 5 in the southeast portion of the state. Announcements regarding Wisconsin’s other three frost zones will be made as weather conditions warrant.

Class II roads include about 1,400 miles of state highways susceptible to damage from heavy trucks during the spring thaw period as frost leaves the ground. More information regarding Class II roadways and roadway postings can be found on WisDOT’s website.

Declaration of Spring Thaw also means suspension of most divisible load overweight permits. Information on overweight permits can be found online. A recorded message with information on road restrictions is available by calling (608) 266-8417.

County highways, town roads, and city and village streets may also be posted or limited to legal load limits or less. Decisions to place or lift weight restrictions on those roads are up to local units of government.
