Spring Load Restrictions
What are Spring Load Restrictions?
Each year during the spring thaw (typically early-March to mid-May), state, county and local agencies impose axle weight restrictions to protect the investment that has been made in their roadways. The two primary causes for premature deterioration of bituminous pavement are weather and traffic load. As the frost is leaving the ground during the spring thaw every year, the gravel under the roadbed has high moisture content, which weakens the load carrying capacity of the bituminous pavement.
In order to protect and prolong the service life of the roadways, axle weight restrictions are imposed during the spring thaw every year, when the roadbeds are most susceptible to damage (due to the weakened subgrade).
When are Spring Load Restrictions in effect?
The period in which restrictions can last vary depending upon frost and weather conditions, but usually last a minimum of eight weeks. Rice County uses the spring load restriction dates set by MnDOT as a guideline for Rice County’s road network.
