Road Restrictions
Spring is always welcomed, especially after a long winter. In stark contrast to the welcomed warmer weather, city roads experience the most stress during the spring. This is because the roadbed is saturated with water thereby significantly reducing the strength of the road surface.
To protect city roads, state law includes a provision for spring load restrictions. The beginning and end of spring load restrictions is determined by the Minnesota Department of Transportation. You can access up-to-date information about the status of spring load restrictions at the MnDOT Seasonal Load Limits website. City of Duluth roads follow the North SLL zone starting and end dates. The beginning and end of spring load restrictions are weather-dependent, however they typically begin in early March and end in mid-May.
Truck traffic should use State Aid routes for travel during spring load restrictions, no truck traffic shall travel on local or residential streets.
