Overweight permits for more than 80,000 pound gross vehicle weight will continue and new permits will be issued if all axle and group weights are legal (axle weight limits).

Full-summer overweight permits can be issued, during the spring load restriction period, for travel on the interstate system only.

Middle-range overweight permits become available within each frost zone when spring load restrictions are lifted. Full-summer overweight permits become available two to three weeks after spring load restrictions are lifted. 

Ending dates for spring load restrictions are variable and based on how weather is affecting roadway strength.
