The highway begins at an intersection with WIS 23/WIS 33 east of Reedsburg. From there, it runs south along Copper Creek. Where Copper Creek drains into the Baraboo River, the highway follows the river in a southeasterly direction to Rock Springs, where it intersects WIS 154 and County Trunk Highway DD (CTH-DD). The highway then runs north of the Baraboo River in an easterly direction from Rock Springs. It intersects CTH-I and continues east and then starts running along Linn Street into West Baraboo. It intersects US 12, where it starts running concurrently with WIS 33 until the concurrency ends at Pine Street, on which it runs south. The highway continues along the Pine Street alignment until it curves to the west, at which point the highway runs east from it. The highway then reaches CTH-DL, and runs concurrently with it until ending at the entrance of Devil's Lake State Park.^[1][2]

A highway running near or along the Baraboo River from Reedsburg to Baraboo was designated when the state highway system was established in 1917 as part of WIS 33.^[3] In 1935, WIS 33 was rerouted to the north and the bypassed section was redesignated as WIS 136. A former WIS 136 designation running from the current route near North Freedom to Prairie du Sac was downgraded to a County Trunk Highway.^[4][5]

In 2017, the route was extended onto the old US 12 route, when a freeway was built in Baraboo.

The entire route is in Sauk County.
