Where Wisconsin trucks run
I-94, I-90, I-39 and I-43 carry most truck freight, linking Milwaukee, Madison and the Fox Valley to Chicago and the Twin Cities, with Green Bay and the Great Lakes ports serving paper and agricultural shippers. The busiest freight markets include Milwaukee, Madison, Green Bay, Appleton (Fox Cities), Eau Claire and La Crosse.
Dairy, cheese, paper and manufactured goods dominate outbound freight, and seasonal spring weight limits (frost laws) on local roads affect rural hauling.
