Spring Load restrictions have already ended in the other frost zones.
Frost zones and restricted routes can be found on the MnDOT load limits map.

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