A pair of signs warn motorists of the impending end of the 17.5 mile long freeway portion of U.S. 12. The freeway begins at the Illinois state line near the town of Genoa City. Mainline U.S. Highway 12 defaults onto the partial diamond interchange with Wis 67 where the two routes share alignment for 7.8 miles before the U.S. highway resumes a westward trajectory toward Madison. Elkhorn, the county seat of Walworth County, lies 2 miles south along Wis 67.

Motorists are directed onto the ramp leading to Wis 67. The freeway was slated to continue northwest to Madison before local opposition postponed any sort of extension. A stub exists for the eventual continuation of the westbound lanes. Any extension of the freeway will ultimately result in the modification of the interchange as currently the ramp entrance for U.S. Highway 12 east crosses underneath the Wis 67 overpasses.

Wis 67 meanders 160.1 miles through the state, commencing from Illinois Route 75 southeast of Beloit to an eventual end at U.S. 151 in southwestern Manitowoc County. Primarily a north to south route, the state trunk highway consists of a few lengthy east-west segments, including one between the community of Lomira near U.S. 41 in Dodge County and Plymouth in Sheboygan County. With several extensions over the years, the last one in 1999 lengthened Wis 67 west from Wis 140 in Rock County.
