Located in Milwaukee, Racine, and Kenosha counties, Interstate 94 is a key connector to local and national businesses with one of the highest concentrations of trucking in the nation. However, years of wear and tear and an obsolete design had raised safety concerns. The Wisconsin Department of Transportation began work on a $410.5 million upgrade effort that improved safety, saved time, and saved money by using techniques such as placing ground heaters to control frost in order to allow construction continue in the colder months. The project built 18 new bridges, four new interchanges, and added 1.15 million yards of new pavement in addition to other maintenance upgrades. WisDOT alleviated traffic congestion during the construction by maintaining at least three lanes of traffic at a time. WisDOT kept the public and impacted business updated throughout with updates on closures and detours. This all resulted in a finished product that kept Wisconsin moving.
