You may have to check your routes if you plan on driving heavy machinery throughout the state as spring begins to rear its head in Wisconsin.

The Wisconsin Department of Transportation ended its frozen roads period last Friday and shortly after began its Class II roadway restrictions.

The restrictions apply to state highways that are susceptible to damage from heavy vehicles during the spring thaw. County highways, town roads, and city and village streets may still have their own restrictions in place.

The seasonal weight restriction program is enacted each year to help prolong the life of Wisconsin highways. Class II roadway restrictions typically last from early March until the first weekend in May.
