County roads experience the most stress during the spring. This is because the road bed is saturated with water thereby significantly reducing the strength of the road surface. 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
. The beginning and end of spring load restrictions is weather dependent, however they typically begin in early March and end mid-May.
Once blanket spring load restrictions are removed, individual roads (typically gravel 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.
