Road Restrictions

Protecting the Roads to Increase Their Life & Ensure Safe Driving

St. Louis County reserves the right to seasonally restrict the operation of vehicles on County Roads (CR), County State Aid Highways (CSAH) and Unorganized Township (UT) roads per Minnesota Statue 169.87: Seasonal Load Restriction; Route Designation. Questions concerning any county maintained road should be directed to one of the Maintenance Superintendents listed on the Maintenance District map or by clicking on the relevant Maintenance District link to the right.

Spring Road Restrictions:

Spring load restrictions on St. Louis County highways begin:
North-Central Frost Zone on Wednesday, March 21, 2018 at 12:01 a.m; 

North Frost Zone on Thursday, March 22, 2018 at 12:01 a.m; 

The North-Central Zone includes the area south of US Highway 2 and west of State Highway 33. The North Zone includes the area north of US Highway 2 and east of State Highway 33. Information on zone boundaries can be obtained by clicking here for Mn/DOT's Seasonal Load Limits.

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 2018 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.
