Spring road restrictions announced for St. Louis County roads in North
and North Central Zones

Spring road restrictions have been announced for the North-Central and North frost zones of  Minnesota. Restrictions will go into effect on Tuesday, March 19, 2019, at 12:01 a.m. These two zones include all highways in St. Louis County.


The restrictions are as follows:


Unpaved Roads: Any unposted unpaved roads are limited to five (5) tons per axle. Roads may accommodate higher than the five (5) ton limitation, only if the postings are in place.


Paved Roads: All paved roads will be posted with the effective per axle weight restrictions.


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. Highway maintenance vehicles, mobile library units,
school buses, and emergency public utility vehicles fall under specific requirements as described in Minnesota Statute 169.87, Subd. 3, 4, 5 & 6.


The ending dates for spring load restrictions are based on how weather is affecting roadway strength. These dates vary as weather conditions change, but typically take place in May. Load restriction maps can be viewed online at stlouiscountymn.gov/roadrestrictions. Information on zone boundaries can be found on the Minnesota Department of Transportation’s website at  mndot.gov/loadlimits.
