Interstate 90 (I-90) runs east–west through the western, central and southern portions of the U.S. state of Wisconsin. About 187 miles (301 km) of I-90 lie in the state.
Route description
The highway enters from Minnesota over the Mississippi River just northwest of La Crosse. The freeway passes north of La Crosse and south of Onalaska as it heads towards Tomah. Once there, it joins I-94. The two Interstates run concurrently for the next 91.76 miles (147.67 km) to Madison. The highway collects Interstate 39, 63 miles (101 km) southeast of Tomah (near Portage). This concurrency of about 30 miles (48 km) is one of only two three-route concurrency of the Interstate Highway System existence, the other being in Milwaukee. I-39 continues along I-90 for the remaining 78 miles (126 km) in Wisconsin.
I-94 breaks away eastward toward Milwaukee at what is commonly known as the Badger Interchange, where the three Interstates meet with WIS 30. The remaining routes continue south to Janesville and Beloit before exiting the state.
