St. Louis County highways located in the North-Central Frost Zone are posted as of Monday, March 6, 2017. The North-Central Zone includes the area south of US Highway 2 and west of State Highway 33.
Restrictions are as follows:
Unpaved Roads - Any unposted unpaved roads are limited to 5 tons per axle. Road postings higher than the 5 ton limitation are effective only if the postings are in place.
Paved Roads - All paved roads will be posted with the effective per axle weight restrictions.
For more information related to per axle weight restrictions, refer to our 2017 Road Restrictions Maps. This map is color coded to show the road rating in tons and can assist with transportation planning.
This is pursuant to Minnesota Statutes 169.87 and St. Louis County Ordinance No. 13 dated March 13, 1972. Information on zone boundaries are detailed on the MnDOT website.
Highway maintenance vehicles, mobile library units, school buses, and emergency public utility vehicles fall under specific requirement as described in Minnesota Statute 169.87, Subd. 3, 4, 5 & 6. Propane and fuel oil haulers should consider topping off their customers’ tanks prior to the posting of spring load restrictions since their hauling vehicles are overweight on many of the posted County roads even when empty.
Note: St. Louis County will not grant exemptions during Seasonal Load Restrictions unless it is detrimental to public health and safety. In the event you are in need of an exemption, please email Victor Lund, Principal Engineer - Traffic, or call 218-625-3873. Once Spring load restrictions are applied they remain in effect until Mn/DOT lifts them. Even after blanket spring load restrictions are removed, individual roads may remain posted based on their condition until they recover and are able to carry full legal loads. These individual decisions are made by the maintenance superintendents.
