Project location

WIS 23, County P (west of Plymouth) to WIS 32 (Sheboygan Falls), in Sheboygan county.

Project overview

  • WIS 32 is a 10 mile long four-lane divided expressway with at-grade intersections and passes along the north of both Plymouth and Sheboygan Falls.
  • WIS 23 is a connector route in the Connections 2030 plan. It is a major east-west highway connecting US 41 and I-43 between the Fox Cities and Milwaukee, and provides a direct route between Fond du Lac and Sheboygan.
  • The study will address issues associated with WIS 23 between County P and WIS 32 and will look to develop alternatives that will be needed to convert this section of WIS 23 to a freeway to provide the type of service consistent with a Connections 2030 connector route.
  • In order to obtain the freeway designation, all current access to the expressway will be modified, resulting in an interchange, overpass, or a road closure. Highway preservation is done according to State Statute 84.295.
  • After evaluation of the alternatives WisDOT will map the right of way needs for the location of future overpasses and interchanges.
  • No construction is planned as a part of this study. Implementation of the improvements will occur as determined by future operational needs.


  • Preliminary design and environmental documentation. No construction activity.
  • Study scheduled to be completed 2014.
