The highway enters from [Minnesota](/source/Minnesota) over the [Mississippi River](/source/I-90_Mississippi_River_Bridge) just northwest of [La Crosse](/source/La_Crosse%2C_Wisconsin). The freeway passes north of La Crosse and south of [Onalaska](/source/Onalaska%2C_Wisconsin) as it heads towards [Tomah](/source/Tomah%2C_Wisconsin). Once there, it joins [I-94](/source/Interstate_94_in_Wisconsin). The two Interstates [run concurrently](/source/Concurrency_(road)) for the next 91.76 miles (147.67 km) to [Madison](/source/Madison%2C_Wisconsin). The highway collects [Interstate 39](/source/Interstate_39), 63 miles (101 km) southeast of Tomah (near [Portage](/source/Portage%2C_Wisconsin)). This concurrency of about 30 miles (48 km) is one of only three triplex concurrencies of the [Interstate Highway System](/source/Interstate_Highway_System) existence, the other two being in both [Milwaukee](/source/Milwaukee) and [Indianapolis](/source/Indianapolis). I-39 continues along I-90 for the remaining 78 miles (126 km) in Wisconsin.

I-94 breaks away eastward toward [Milwaukee](/source/Milwaukee%2C_Wisconsin) at what is commonly known as the Badger Interchange, where the three Interstates meet with [WIS 30](/source/Wisconsin_Highway_30). The remaining routes continue south to [Janesville](/source/Janesville%2C_Wisconsin) and [Beloit](/source/Beloit%2C_Wisconsin) before exiting the state.

## History

In 1959, I-90 was extended north from Rockton Road, the Northwest Tollway's (now Jane Addams Memorial Tollway's) northern terminus, in Illinois to US 14 near Janesville, Wisconsin.[2][3][4][5] In 1961, another section of I-90 was opened. This section ran from US 12/US 18 (later moved slightly southward) near Madison to US 12/US 16 (now US 12/WIS 16) near Wisconsin Dells.[6][7] In 1962, a connection between both opened sections opened to traffic.[7][8] In 1964, I-90 was extended northwestward to US 12/US 16 (now US 12/WIS 16) near Tomah.[9][10]

The [Dresbach Bridge](/source/Dresbach_Bridge), spanning the Mississippi River west of La Crosse, was dedicated and opened to traffic on October 12, 1967.[11] By 1969, another separate section of I-90 was opened, traveling from the Minnesota state line to US 16 (now WIS 16) near La Crosse.[12][13] Later, both opened sections were then connected together.[13][14]

The Dresbach Bridge was replaced by the states of Minnesota and Wisconsin in 2016 under the former's program to replace outdated bridge designs following the [2007 I-35W bridge collapse](/source/I-35W_bridge_collapse). The old bridge was closed in April 2016 and the new structure opened in October.[15]

Starting in 2015, the 45-mile (72 km), southernmost section of I-39/I-90 (from US 12/US 18 to the Illinois state line) underwent a major reconstruction project. This involved widening the corridor to six lanes (eight lanes in the Janesville area) and reconfiguring all interchanges, including the I-43/WIS 81 interchange. The overall project was completed in 2021.[16]
