Each year during the spring thaw, axle weight restrictions are imposed by highway authorities to protect roadways. As the frost leaves the ground in the spring, the gravel under the street has high moisture content, which affects the load carrying capacity of the pavement. In order to prolong the service life of the streets and highways, axle weight restrictions are imposed to help prevent damage due to heavy loads. These restrictions are now in effect in Blue Earth County. View the Blue Earth County Spring Weight Posting Map for more information.
