Interstate 90 in Minnesota
|Get started||Beaver Creek|
Interstate 90 or I -90 is an Interstate Highway in the US state of Minnesota. I-90 forms an east-west route through the south of the state, from the South Dakota border at Manley to the Wisconsin border at La Crescent. I-90 does not serve major cities on its route and passes well south of the Minneapolis-St. Paul along. I-90 does lead closer to the regional city of Rochester. I-90 is 244 miles long in Minnesota.

Just east of Sioux Falls, Interstate 90 crosses the border into Minnesota in South Dakota. I-90 then leads through the flat prairies of southern Minnesota. In particular, the western 350 kilometers leads through monotonous landscape with no larger places on the route. The landscape consists of flat meadows with hardly any vegetation. The most famous places are intersections with other major roads, such as Luverne, where you intersect US 75, and Worthington, where you intersect US 59. I-90 has long straights, the highway runs parallel to the border with the state of Iowa for a short distance. The main place on the western half of the route is Albert Lea, an important truck stopand interchange with I-35.
Just east of Albert Lea, I-90 passes the town of Austin, where it intersects US 218. After this, I-90 curves northeast to walk closer to the city of Rochester. Rochester is the largest city in Southeast Minnesota and located primarily on US 52, which joins I-90 south of Rochester and is a freeway. I-90 then continues east through the meadows to near Winona, from here the highway leads through an area of low hills and more forest, this is the Mississippi River valley. I-90 splits down to the Mississippi River at Dakota and even heads south for a bit. Just before the town of La Crescent, I-90 bends east again and crosses the Dresbach Bridgeacross the Mississippi River, which forms the border with the state of Wisconsin. Interstate 90 in Wisconsin then continues past La Crosse toward Madison.
I-90’s predecessor was US 16, which originally ran much further east, all the way to Detroit. In southern Minnesota, most of I-90 has been constructed over US 16, except at locations where diversions have been made. As a result, US 16 ceased to exist as an individual route. Between 1978 and 1980, US 16 was phased out from Wisconsin to South Dakota, thereby ceasing to exist in Minnesota.
I-90 was of little importance to Minnesota and construction was spread out through the 1960s and 1970s. The first section to open was the Austin Bypass in 1960. In 1961, a short section opened near the South Dakota border. In 1963 the first longer section opened, from Austin to Dexter. The route was built west of Dexter primarily over or along existing US 16, east of it on a new line to also connect the cities of Rochester and Winona. Construction progressed through the 1960s, with the eastern section being completed first to the Wisconsin border in 1972.. Then west of Albert Lea had to be built through the prairies, which mainly took place in the late 1960s and throughout the 1970s. In 1978, the last section of the highway opened to traffic, completing I-90 after some 18 years.

About 10,000 vehicles cross the border into South Dakota, which then stabilizes at about 7,000 to 9,000 vehicles per day, making I-90 very quiet. After Rochester, 14,000 vehicles drive some more traffic on the route, and 17,000 vehicles cross the Mississippi River, which also crosses the Wisconsin border, every day.
