Project location

The WIS 26 Corridor Expansion Project is a 48 mile stretch of roadway, broken into eight segments, on WIS 26 between I-90 in Janesville and the WIS 60 east intersection north of Watertown, it is located in Dodge, Jefferson, and Rock counties.

Project overview

WIS 26 is an important route connecting communities and major highways in Rock, Jefferson and Dodge counties.

It is designated as a long-truck route in the National Highway System (NHS) and as a connector route in the Wisconsin Department of Transportation's (WisDOT) State Highway Plan 2020. Under the plan, connector routes are given higher priority funding since they connect major regions and economic centers.

About half of the expansion will be constructed alongside the existing corridor. The other half, mainly the bypasses, will be constructed on new location. Bypasses will be constructed around Milton, Jefferson and Watertown with interchanges providing easy access to the cities.

The overall cost to purchase real estate, design, and construct the roadway represent an estimated $464 million investment in Wisconsin's transportation system.

Status/phase

The studies for this project have been completed and the project segments below are in various stages of construction:
