'''State Trunk Highway 23''' (often called '''Highway&nbsp;23''', '''STH-23''' or '''WIS&nbsp;23''') is a state highway in the U.S. state of Wisconsin. The highway's route is signed as a north–south route from Shullsburg to Wisconsin Dells and as an east–west route from Wisconsin Dells to Sheboygan. With the exception of freeway segments between Sheboygan Falls and Sheboygan, an expressway segment between Sheboygan Falls past Greenbush to Fond du Lac, a freeway concurrency with Interstate&nbsp;39 (I-39), and an expressway segment concurrent with U.S. Highway&nbsp;151 (US&nbsp;151), the highway is generally either two-lane surface road or urban multilane arterial. WIS&nbsp;23 provides access to several important Wisconsin destinations, such as the House on the Rock, the Wisconsin Dells area and various state parks.

WIS&nbsp;23 was relocated in the Sheboygan area to bypass Plymouth and Sheboygan Falls.

Proposals were considered that would have rerouted WIS&nbsp;23 around Lake Delton by following CTH-H from Reedsburg directly to Wisconsin Dells, but were never pursued due to pressure from the village of Lake Delton and the area's tourist attractions like hotels and resorts fearing lost business from the re-routing.<ref name="WH_23" />

The Wisconsin Department of Transportation (WisDOT) had made WIS&nbsp;23 between Fond du Lac and Sheboygan a priority state corridor in its highway planning, studying the expansion of WIS&nbsp;23 from Fond du Lac to Plymouth to a four-lane expressway, as the rural two-lane portion between Mount Calvary and Greenbush towards the county line, along with the two-lane narrowing just outside of Fond du Lac on a steep grade into the Kettle Moraine State Forest area, was a stretch where various crashes with casualties occurred.
