Seasonal Weight Restriction Lift Notice (pdf)

Road damage done by heavy vehicles during winter and spring thawing periods is a problem that affects all northern states.  Unless a roadway has been designed and constructed for heavy vehicle loads year-round (aka all-weather road), a significant loss of strength occurs during a seasonal thaw period.  The damage to a road is directly related to the amount and frequency of the loading applied. 

State law mandates the institution of weight restrictions on March 1^st of every year,  but the statute also allows the Michigan Department of Transportation and the county road commissions to implement those restrictions earlier or suspend reduced loading, depending on weather and road conditions.  Historically, the Livingston County Road Commission has implemented the Springtime Weight Restrictions the last week of February.

Along with reduced loading provisions are reduced speeds. For vehicles over 10,000 pounds operated on seasonally restricted roads, the speed limit drops to a maximum of 35 mph, regardless of the posted limit. Speed, in conjunction with axle and wheel loading, contributes to road damage including the creation of potholes.
