Interstate 39/90/94: A Vital Stretch in Wisconsin
Interstate 39/90/94 in Wisconsin is a major stretch of the Interstate Highway System where three significant routes run together through the south‑central part of the state. For about 29 miles from near Madison northward toward Portage, Interstate 39, Interstate 90, and Interstate 94 share the same roadway, making this concurrency not unique but also one of the longest three‑route overlaps in the entire U.S. Interstate network.
This combined highway carries traffic from important metropolitan areas and serves as a principal corridor for both regional travel and long‑distance freight. I‑90 runs east–west across much of Wisconsin, connecting the Minnesota and Illinois state lines, while I‑94 enters from the northwest and continues southeast toward Milwaukee and Chicago. Interstate 39 brings traffic up from Illinois, linking with both of these major east‑west routes.
Because it carries heavy commercial traffic and connects key urban centers, tourism destinations, and economic regions, I‑39/90/94 is vital to the state’s transportation network and commerce. It also links to other major highways, facilitating movement between local and national routes and supporting both daily travel and interstate commerce.
