2019 SPRING LOAD RESTRICTIONS on all Mahnomen County Roads and Highways went into effect in accordance with Minnesota Statute 169.87 with the implementation of the Mn/DOT North Central Spring Load Restrictions at 12:01 a.m. on March 19, 2019. 

The weight restriction signs shall govern when installed on the system.  The load limits are enforced as the restriction signs are placed on these roadways. The restrictions will remain in effect until the signs are removed by Mahnomen County in about mid-May as conditions improve.  If conditions indicate pavement failure, gross axle weight restriction limits will be reduced.
