Spring truck weight restrictions on highways in southern Minnesota begin today (FRI). Mn/DOT limits truck weights to limit damage to roads weakened during the spring thaw. Brown County also imposes weight restrictions on county roads to coincide with the state restrictions. All Brown County roadways are restricted to 5, 7, 9 or 10 tons per-axle as indicated by posted signs. Any paved road not marked by signs is restricted to 10-tons, and for gravel roads in Brown County the weight restriction is 5-tons per-axle. Ending dates for spring load restrictions get decided by monitoring road strength as weather conditions change. All changes are made with a minimum 3-day notice. Winter load increases and overweight permits remain in place for the state’s central, north-central and north frost zones.
