In the U.S. state of Iowa, Interstate 29 (I-29) is a north–south Interstate Highway which closely parallels the Missouri River. I-29 enters Iowa from Missouri near Hamburg and heads to the north-northwest through the Omaha-Council Bluffs and the Sioux City areas. It exits the state by crossing the Big Sioux River into South Dakota. For its entire distance through the state, it runs on the flat land between the Missouri River and the Loess Hills. I-29 was built in sections over a period of 15 years. When there was a shortage of male workers, female workers stepped in to build a 20 mi section near Missouri Valley. Between Council Bluffs and Sioux City, I-29 replaced U.S. Route 75 (US 75) as the major route in western Iowa. As a result of I-29's creation, US 75 south of Sioux City was relocated into Nebraska.
