Interstate 680 (I-680) in Nebraska and Iowa is the northern bypass of the Omaha, Nebraska – Council Bluffs, Iowa, metropolitan area. I-680 spans 42.86 mi from its western end in western Omaha to its eastern end near Neola, Iowa. For a 10 mi stretch, I-680 is co-signed with I-29. 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.

Until 1973, the section in Iowa between the current eastern end and I-29 was designated as I-80N. I-680 in Omaha was originally designated 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.
