[4] The highway begins at the Wisconsin–Illinois state line near Bergen as a continuation of Illinois Route 76 (IL 76), and runs north from it.

It meets with brief pockets of forested parkland and runs through farmland, passing through intersections with WIS 67 and County Trunk Highway P (CTH-P).

It then crosses a railroad before reaching the village of Clinton, where it intersects with CTH-X and CTH-J.

[1][2] The busiest part of the highway is within the village of Clinton, which has an Annual average daily traffic (AADT) count of 5,600.

The highway then passes by a small community and runs across Turtle Creek before swerving slightly to the east.
