Interstate 680 (I-680) in Nebraska and Iowa is the northern bypass of the Omaha–Council Bluffs metropolitan area. I-680 spans 16.49 miles (26.54 km) from its southern end in western Omaha, Nebraska, to its eastern end near Crescent, Iowa. The freeway passes through a diverse range of scenes and terrains—the urban setting of Omaha, the Missouri River and its valley, the rugged Loess Hills, and the farmland of Pottawattamie County, Iowa.

From 1973 until 2019, I-680 extended much farther into Iowa. It followed I-29 for 10 miles (16 km) between Crescent and Loveland. It then headed east along what is now known as I-880 until it met I-80 again near Neola. The I-880 section was originally known as I-80N from 1966 until it was absorbed into I-680 in 1973. I-680 in Omaha was originally designated Interstate 280 (I-280). Maps from the early and mid-1960s showed I-280 in Omaha. Since this highway would extend into Iowa and I-280 was already planned for the Quad Cities area, this route was redesignated I-680.
