Frozen road declaration ends Friday for northern Wisconsin

​​​Release date: March 16, 2022

The Wisconsin Department of Transportation (WisDOT) is ending the frozen road declaration for northern Wisconsin Zone 1 as of 12:01 a.m. Friday, March 18 and enacting Class II road restrictions. Declarations for other zones in Wisconsin were lifted earlier this month based on frost tube readings.​

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 frozen road declarations, Class II roadways, and roadway postings can be found on WisDOT’s website under “Weight Restriction Programs.”

County highways, town roads, 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.

More information on overweight permits can be found on the WisDOT website by searching under “oversize overweight permits.” Haulers with specific questions can contact WisDOT’s Oversize/Overweight Permits Unit at (608) 266-7320. A recorded message with general information on road restrictions is available by calling (608) 266-8417.
