According to the Chippewa County Highway Department, seasonal load restrictions take effect this Friday, March 15 at 12:01 AM. Seasonal load restrictions protect roads during the spring thaw, when road strength is at its lowest point of the year. All county paved roadways will be restricted to 10 ton per axle unless posted otherwise, and county and township gravel roads will be restricted to 5 tons per axle. Ending dates for spring load restrictions are variable depending on how the weather affects roadway strength.
