Project location

I-94 and WIS 26 interchange, Johnson Creek - Jefferson County

Project overview

The Wisconsin Department of Transportation (WisDOT) is proposing improvements along 1.26 miles of I-94. The project starts at the County Y underpass and ends approximately 2,400 feet east of WIS 26.

This proposed project will prolong the service life of the existing concrete pavement and structures.

Proposed Improvements:

  • Concrete surface repair and spot replacement of the existing concrete pavement of I-94, the ramps, and pavement between the ramps
  • Existing shoulder pavement will be milled and overlaid with new asphalt pavement or replaced as needed
  • Existing asphalt pavement at the park and ride on North Watertown Street will be milled and overlaid
  • Existing curb ramps adjacent to the park and ride driveway, bus stop, and along the west side of North Watertown Street will be upgraded to meet Americans with Disabilities Act (ADA) standards
  • Repairs will be made to bridge structures

There are no temporary or permanent real estate acquisitions, or relocations anticipated with the project.

Persons with a concern for or knowledge about historic buildings and structures and archaeological sites are encouraged to provide comments.

We encourage you to share this information with others that may be affected by this project.
