Project Description: This is the second of the major reconstruction projects that Batterman had the opportunity to manage on the IH-39/90 expansion project for the Wisconsin Department of Transportation. This project consisted of removing the existing lanes of IH-39 for both northbound and southbound and expanding from a four-lane highway to a twelve-lane highway through the city of Janesville. All of the new concrete pavement was constructed using 3D machine-controlled pavers rather than the traditional string-lined paver. Two of these lanes in either direction facilitate the traffic using the entrance and exit ramps to the central business district of the city. This project had eight reconstructed bridges over city roads and highways as well as two new bridges that accommodate a new city street. Massive mechanically stabilized earth walls were required in order to minimize right-of-way purchases. State Highway 26 was constructed into a Diverging Diamond Interchange, making one of only the three of its kind built in the state of Wisconsin.

Biggest Challenge and How it was Solved: This project was extensively staged to always accommodate two lanes of traffic in each direction at all times. This was achieved by coordinating with WisDOT staff and adjacent projects.
