Interstate 39, Interstate highway in Illinois and Wisconsin, United States
Interstate 39 extends 306 miles from Normal, Illinois to Wausau, Wisconsin, serving as a primary north-south transportation route through both states.
Construction of Interstate 39 started in 1979 following concerns about safety issues on U.S. Route 51, which experienced numerous accidents during the 1960s.
The highway connects multiple educational centers, including Illinois State University in Normal and the University of Wisconsin campuses in Madison and Stevens Point.
The route provides direct access to major distribution centers and industrial parks, supporting economic development in cities like Rockford, Janesville, and Madison.
Interstate 39 forms part of the longest three-interstate convergence in the United States, combining with I-90 and I-94 for 29 miles in Wisconsin.
