Sheboygan County Road Projects Keep Several Routes Under Construction Into Fall
Sheboygan County, WI — September 8, 2026.
Several Sheboygan County-maintained road projects are listed for work continuing into fall, but the impacts vary by route. Some roads are fully closed, while others have daily closures or reconstruction work that may require extra travel time.
The latest county construction update cited for this article was updated August 26, 2026. It lists active work on County Roads TT, C, OO, I, A and SS. Drivers should follow posted detour signs and check the county’s current construction information before leaving for work, school, appointments, deliveries or fall activities.
Quick guide to the county road projects
- County Roads TT and C: Both roads are listed as closed through October 2026. The county says there is no access to or from State Highway 23 in the affected area.
- County Road OO: The road is under full reconstruction, with work expected to be completed in September 2026.
- County Road I: Daily closures are scheduled through September 30, 2026.
- County Road A: Daily closures are expected to continue into October 2026.
- County Road SS: The road is fully closed for bridge reconstruction through November 2026.
What drivers should do
The different closure types matter for route planning. A full closure requires drivers to use an alternate route, while a daily closure may affect trips during posted work periods. Reconstruction areas can also bring changing access conditions as crews move through each phase.
Drivers should follow official county detour signs, allow additional time and avoid assuming that a familiar route will remain open. Businesses and delivery drivers may want to review routes in advance, especially where County Roads TT or C are affected by the lack of access to or from State Highway 23.
These projects are separate from the I-43 pavement work listed for September 8 and 10. The Sheboygan County Highway Department oversees the county trunk highway system, while WisDOT maintains separate information for state highway projects.
Construction schedules can change because of weather, field conditions and project progress. Check the Sheboygan County Highway Department’s current construction information before traveling through an active work area.
