History

Bellevue Bridge

Designated in 1953, Iowa 370 originally extended 5.5 miles (8.9 km) from Bellevue, Nebraska, to US 275. The eastern end of the route was in Pottawattamie County.^[2] In the early 1980s, Iowa 370 was truncated at I-29. The segment in Mills County from I-29 to the Pottawattamie County line was inventoried as Iowa 935 until July 1, 2003.^[3]

Upon completion and opening of the new US 34 bridge over the Missouri River, Iowa 370 was turned over to Mills County.^[4]

Major intersections

The entire route was in St. Marys Township, Mills County.
