MILWAUKEE, Wis. (WTAQ) - Trucks that carry forest products, road salt, and sand can carry heavier loads in southeast Wisconsin starting Wednesday.

The annual “Frozen Road Law” took effect in the rest of the state on December 17th, and it begins in the southeast at 12:01 a.m. Wednesday.

Heavier weight limits apply to forest and winter maintenance trucks on all state and federal highways except the Interstates. But it does include I-39 from Portage to Wausau.

The Frozen Road Law stays in effect until early March, unless thawing justifies an earlier ending.
