Spring thaw - Seasonal Weight LImit Information

In spring, roads begin to thaw from both the top and bottom. As ice in the pavement melts, water saturates the road’s base and subgrade. These layers lose strength, like a handful of mud compared to dry soil. As thawing continues, melt water becomes trapped in the upper subgrade, unable to drain away through the frozen soils below. Pavements weaken considerably in a very short time under these conditions. (Wisconsin Transporatation Bulletin #8, Wisconsin Transporation Information Center, 2003)

During this spring thaw, the Highway Department posts most County Highways with Seasonal Weight Limits.  Additional information on the Seasonal Weight Limits and the locations of the weight limits can be found in the Driving Information Page of this site.

As of 3-3-2015, no dates have been determined for posting Seasonal Weight Limits.  Information will be posted on this page when it is available.  Please Check back regularly for any updates.
