State Trunk Highway 23 (often called Highway 23, STH-23 or WIS 23) is a state highway in the U.S. state of Wisconsin. The 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 39 (I-39), and an expressway segment concurrent with U.S. Highway 151 (US 151), the highway is generally either two-lane surface road or urban multilane arterial. WIS 23 provides access to several important Wisconsin destinations, such as the House on the Rock, the Wisconsin Dells area and various state parks.
