WIS 23 Expansion - Sheboygan/FDL

Sheboygan/Fond du Lac Counties

Project Overview

Update: Project complete! Due to weather, punchlist items and some repair work will take place in Spring 2023.

WIS 23 Project Benefits

WIS 23 improvements will provide the following benefits:

  • Provide a safe and dependable highway connection to and from regional communities while reducing conflicts between local and through traffic.
  • Improve the highway facility to meet current design standards for this Connector route in Wisconsin.
  • Complete the system link of I-41 to I-43 between the cities of Fond du Lac and Sheboygan.
  • Improve safety at intersections and farm crossings.
  • Increase corridor mobility and minimizing public and private access.
  • Preserve the corridor for future transportation use by coordinating local governmental land use plans. This will alleviate development pressures on WIS 23 and intersecting roads, preserving the corridor for future transportation use.
  • Maintain a rural highway-type facility while addressing the increased traffic needs of the expanding urban area.
