According to bestitude, US 71 is a US Highway in the US state of Iowa. The road forms a north-south route through the west of the state, generally about 30 miles east parallel to US 59. The road mainly connects villages and a few small towns. The road is 380 kilometers long.

Travel directions

US 71 in Missouri comes from St. Joseph, the Northern Missouri countryside continues into Iowa. US 71 heads north through western Iowa, a sparsely populated region of endless meadows. There are no larger towns on the route, but it does cross all of Iowa’s east-west routes. US 71 runs parallel to US 59 about 30 to 50 kilometers away. There are no highways near US 71, but Interstate 80 is crossed at Atlantic.

The US 71 is almost everywhere a single-lane road. There are very short 4 lane stretches in a number of places such as Audubon and Spencer. A 15 kilometer section between Spencer and Milford has also been constructed as a 2×2 divided highway. The scenically most interesting area is around Spirit Lake in northern Iowa, where US 71 runs through the Okoboji Lake Lake District. US 71 in Minnesota continues to Jackson and Willmar.


US 71 was created in 1926. The route is one of the less important north-south routes in Iowa because it doesn’t visit major towns. Despite this, part of the route in the north of the state, between Spencer and Spirit Lake, has been widened to 4 lanes. In the 1980s only a small section at Spencer was four lane, but in the second half of the 1990s the route further north was also widened to 4 lanes.

Traffic intensities

The road is generally not busy, with usually between 1,000 and 3,500 vehicles per day. The 2×2 section from Spencer to Spirit Lake is somewhat busier with 8,500 to 13,300 vehicles. 1,500 vehicles cross the Minnesota border every day.

According to biotionary, US 75 is a US Highway in the US state of Iowa. The road forms a north-south route in the northwest part of the state, from the Nebraska border at Sioux City to Rock Rapids at the Minnesota border . The road is 125 kilometers long.

Travel directions

US 75 in Nebraska runs west of the Missouri River, crossing the river via Interstate 129 and US 20, before forming the freeway bypass of Sioux City. US 75 crosses Interstate 29 and continues around the city. From Sioux City, US 75 is part of a corridor to Minneapolis that has been developed as a 2×2 divided highway. US 75 follows this corridor for more than 30 kilometers to Le Mars, after which US 75 turns north. The rest of US 75 is a single-lane road through the flat countryside of northwestern Iowa. US 75 then passes through two more places over a length of 80 kilometers, Sioux Center and Rock Rapids. The US 75 in Minnesotathen continues to Luverne and Fargo.


US 75 was created in 1926. US 75 followed a longer route through Iowa from 1926 than it does today, between 1926 and 1984 US 75 entered the state of Iowa at Council Bluffs and then headed north to Sioux City on the east bank of the Missouri River. With the construction of I-29 between Council Bluffs and Sioux City between 1958 and 1967, the throughput of the old route was lost and US 75 was routed over I-29. In 1984 the route was changed so that US 75 only entered the state of Iowa at Sioux City.

The Sioux City bypass was originally only around the south side of the city and part of I-129 and US 20. At the time, US 75 passed through downtown Sioux City. In the period 1998-2001, the eastern part of the bypass of Sioux City was constructed. This meant that through traffic to the north no longer had to pass through the city. The northern portion of the bypass between US 20 and old US 75 opened on November 19, 2001.

Already in the late 1950s, the US 75 between Sioux City and Le Mars was widened to 2×2 lanes. A grade-separated bypass of Le Mars was constructed between 2004 and 2006, this project was part of a larger project to widen the route from Sioux City to Minneapolis to 2×2 lanes, of which US 75 is only a small part. The Le Mars bypass opened to traffic on November 22, 2006.

North of Le Mars, the US 75 has not been upgraded, this is part of a hundreds of kilometers long route through Iowa and Minnesota that does not open up larger towns.

Traffic intensities

The Sioux City bypass counts down from 21,000 to 13,200 vehicles and 12,000 vehicles to Le Mars. Further north, 3,300 descending to 1,200 vehicles per day drive all the way to the Minnesota border.
