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-mile (32 km) section near Missouri Valley. Between Council Bluffs and Sioux City, I-29 replaced U.S. Highway 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.

History
Construction of I-29 began in the late 1950s in the Sioux City area. The first section to open, a three-mile-long (4.8 km) stretch from the
North of Council Bluffs, a 20-mile (32 km) section to Missouri Valley opened in November 1958. By December 1967, the two sections were connected, creating 100 miles (160 km) of continuous interstate highway.[2] Due to a shortage of male workers, at least 20 women were enlisted to help build this section of I-29. The women were paid $2.00 hourly (equivalent to $18.28 hourly in 2023[8]), the same wage as men would have earned.[9]
Construction of I-29 in the Council Bluffs area was completed in 1970, and the route was open to Glenwood in the same year. Additional interchanges were added in the Sioux City and Council Bluffs areas between 1970 and 1971. The last 30 miles (48 km) of Interstate were constructed and opened in sections over the next two years; the last section opened on December 15, 1972.[2]
In 1973,
Much of I-29 was built next to existing highways, most notably
