The project is expected to be complete in September with landscaping in the fall.
Work includes constructing a four-lane divided highway and many safety improvements.
The contractor, Vinton Construction Co. of Manitowoc, is scheduled to reopen the roadway by September and finish landscaping later this fall. WIS 175 will be closed to through traffic. A detour route will be signed along US 45, said Project Manager Mark Klipstein of the Wisconsin Department of Transportation. The work is part of separate projects totaling 2.2 miles. The first project, which finished last year, extended Peters Avenue slightly less than one-half mile from Scott Street to the Supple Creek bridge.
