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.[1][2][3][4] 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.[5][6] In 1962, a connection between both opened sections opened to traffic.[6][7] In 1964, I-90 was extended northwestward to US 12/US 16 (now US 12/WIS 16) near Tomah.[8][9]

The Dresbach Bridge, spanning the Mississippi River west of La Crosse, was dedicated and opened to traffic on October 12, 1967.[10] 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.[11][12] Later, both opened sections were then connected together.[12][13]

The Dresbach Bridge was replaced by the states of Minnesota and Wisconsin in 2016 under the former's program to replace outdated bridge designs following the 2007 I-35W bridge collapse. The old bridge was closed in April 2016 and the new structure opened in October.[14]

Starting in 2015, the Script error: No such module "convert"., 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.[15]
