Travel directions

The Dresbach Bridge over the Mississippi River at La Crosse.

The junction of I-90/94 and I-39. “Clear Dells” is short for the tourist town of Wisconsin Dells.

Via the Dresbach Bridge, I-90 crosses the Mississippi River, which forms the border with the state of Minnesota. Interstate 90 in Minnesota comes from the prairies and leads on the Wisconsin side past the town of La Crosse, which is the first major town on the route from Sioux Falls. I-90 crosses French Island here, on which La Crosse Municipal Airport is located. I-90 then heads east through an area of ​​forests, meadows, and low hills, making it a diverse route. After 70 kilometers you reach I-94 at Tomah.

From Tomah, I-90 and I-94 are double numbered. This is quite a long run-up. I-90/94 veers southeast here. The highway has 2×2 lanes and leads through a rural area with quite a lot of forest. The highway sometimes has a fairly wide and wooded median strip. There are a number of small towns along the route, Wisconsin Dells being by far the best known. South of Wisconsin Dells, US 12 is crossed, which runs as a freeway to Baraboo. I-90/94 then heads east to Portage, whereupon triple-numbering begins, as I-39 joins it. I-39/90/94 then heads south and has 2×3 lanes. Cross the Wisconsin River shortly after the interchange with I-39. To the south the landscape becomes more open, with flatter meadows.

After more than 40 kilometers you reach Madison, the capital of Wisconsin. The highway runs through the eastern suburbs and has interchanges with US 51, US 151 and I-94 in quick succession. On the east side of Madison, I-94 exits to Milwaukee. I-39 and I-90 continue south together, counting 2×3 lanes to the Illinois border. I-39/90 then heads south through rolling farmland, with smaller towns on the route. I-90 passes Janesville and then reaches the border town of Beloit, where I-43 joins and follows the border with the state of Illinois. Interstate 90 in Illinois then continues south to Rockford and Chicago.

History

The first section of I-90 built in Wisconsin was an extension of the Jane Addams Memorial Tollway in Illinois and opened in 1959 between the north side of Janesville and the Illinois border. In 1961, a fairly long stretch of about 50 miles (80 km) opened in the middle of the state, between Wisconsin Dells and Madison. This piece is double numbered with I-94. In 1962 the link between Madison and Janesville opened to traffic, again a significant stretch of about 55 kilometers. In 1964, the existing stretch was extended northwestwards to the junction with I-94 in Tomah, a stretch of approximately 40 miles. In 1967, the bridge over the Mississippi River at La Crosse opened to traffic, connecting the highway to Interstate 90 in Minnesota.connected. In 1969, the missing link between La Crosse and Tomah opened to traffic for about 55 miles, completing I-90.

On October 24, 2016, a diverging diamond interchange opened at Exit 177 just south of Janesville. This was the first DDI in Wisconsin. On November 12, 2019, a 20-mile widening to 2×3 lanes was completed between Edgerton and Madison. In 2020, a widening to 2×3 lanes was completed between Janesville and Edgerton. The last section between Beloit and Janesville was delivered on December 3, 2021.

Traffic intensities

22,400 vehicles cross the Minnesota border every day, increasing to 34,500 vehicles in La Crosse. East of the city, the intensities drop to around 20,000 vehicles, and later to 13,000 vehicles. From Tomah, where the double numbering starts with the I-94, the intensities rise to 34,500 vehicles per day. After I-39 joins it, this rises to 53,800 vehicles. Near the capital Madison, I-90 peaks at 85,600 vehicles per day, then drops to 42,800 on the Illinois border.
