Overview

Omaha, Nebraska Map
Interstate 680 previously circled around the outskirts of Omaha, but suburban expansion pushed the city limits westward all the way to the Elkhorn River. The freeway still provides a bypass for regional traffic along I-80 between Lincoln and Des Moines.

Interstate 680 forms a belt route encircling Omaha from the Prairie Lane neighborhood to the Missouri River at Wyman Heights. The route within Nebraska is mostly suburban, with development lining the freeway frontage from I-80 north to 72nd Street (Exit 9). Suburban expansion in Omaha westward along Highway 64 (Maple Road), the West Dodge Expressway (U.S. 6) and Center Road (former N-38) adds commuter traffic to Interstate 680. I-680 changes cardinal directions from north-south banners between I-80 and 72nd Street to east/west banners for the remainder of the route into Iowa.

Crossing the Mormon Bridge over the Missouri River, I-680 traverses a flood plain east to the cloverleaf interchange with I-29 and County Road G37 outside the city of Crescent. I-680 ends at the rural exchange, but previously combined with Interstate 29 north paralleling the Missouri and Boyer Rivers to Loveland. I-680 branched eastward from I-29 across the Loess Hills, where a vista point is located along the scenic and lightly traveled freeway leading to Interstate 80 near Neola.

The American Association of State Highway and Transportation Officials (AASHTO) approved a request from the state of Iowa on October 5, 2019 to renumber I-680 between I-29 at Loveland and I-80 near Minden as Interstate 880. This action included the removal of I-680 from the 9.91 mile long overlap with Interstate 29. Referencing closures of I-29/680 during Missouri River flooding in 2019, the application read:

This new Interstate route is being established to help avoid routing confusion during flooding events that have occurred recently in this area.

History

I-680 - Mormon Bridge
The Mormon Bridge carrying Interstate 680 traffic across the Missouri River. 03/30/16

The Mormon Pioneer Memorial Bridge, a pair of cantilever bridges across the Missouri River at Florence Bend and north Omaha, carries Interstate 680 from Nebraska to Iowa. The original span opened to traffic on December 14, 1952,1 as it connected N-36 with Iowa 988. The 1,603 foot long bridge carried two-way traffic across a 26 foot wide deck.2 The westbound bridge opened to traffic as a toll free route in 1975. Tolls remained in place along the eastbound span at a rate of 75 cents per passenger car until April 21, 1979. A ceremony was held that day to deed the bridge to the states of Iowa and Nebraska from the Douglas County Nebraska Bridge Commission.3

Originally, what became I-680 was planned in two parts: Interstate 280, the loop from I-80 west of Omaha to I-29 north of Council Bluffs, and Interstate 80N, the independent section of I-680 east of I-29 in Iowa. I-680 was initially proposed for the entire route, but the American Association of State Highway Officials (AASHO) changed it to I-80N on November 10, 1958.4 The I-280 designation was dropped by 1965 once it was realized that Iowa would have had two separate Interstates numbered 280: one here and the other at the Quad Cities (Moline/Bettendorf).

Omaha, NE - 1961 Map
The 1961 Iowa Official State Map shows the original proposed numbering of I-680 as I-280 on the bypass around Omaha and Council Bluffs. Map scanned by Jeff Morrison, 02/03/07. The Rand McNally North American Road Atlas showed Interstate 280 on the Omaha inset until the 1967 edition.
Council Bluffs, IA - 1972 Map
Interstate 80N, one year before the renumbering to I-680 – 1972 Iowa Official Highway Map. The Neola Diagonal, I-80 northeast from I-29 to I-680, was the alignment advocated by Council Bluffs and Omaha officials during the early Interstate system development. Iowa officials pushed for the route west to Loveland and I-29 to benefit Sioux City.
Omaha, NE - 1972 Map
Interstate 680 completed north to 72nd Street – 1972 Nebraska Official Highway Map. I-680 was open north to Highway 64 (Maple Street) by 1969 and under construction from there north to the new alignment of Highway 133 (Blair High Road).

The concurrent section with I-29 was completed as Interstate 29 opened from 16th Street (Exit 56) north at Council Bluffs to U.S. 30 (Exit 75).5 A short stretch of I-680 opened from the temporary end of I-80 north to U.S. 6 (W Dodge Road) within Omaha in 1961.6 Interstate 80N opened from I-29 near Loveland to I-80 in conjunction with I-80 east to U.S. 59 on December 13, 1966.5

As approved by AASHTO on November 10, 1973, Interstate 680 was extended north along I-29 and then east along former I-80N. This lengthened I-680 another 26 miles. The remainder of the route was completed on August 14, 1974 after a dedication ceremony preceded the opening of I-680 from Mormon Bridge Road (Exit 12) east to the Mormon Bridge.7

A ten year, $325 million project to improve Interstate 80 across Omaha included a redesign of the three-wye interchange with I-680 in Omaha. The upgrade included adding collector distributor roadways to serve local traffic on both freeways for West Center Road (Exit 1) to the north and U.S. 275 (Exit 445) to the southwest. The project started in Spring 1994 as work neared completion on the interchange redesign between I-80, I-480 and U.S. 75 (Kennedy Freeway) to the east.8,9 Work at the exchange ran through December 199710,11 while construction to expand I-680 to six lanes from Pacific Street (Exit 2) to U.S. 6 (Exit 3) followed between 1998 and December 13, 1999, when the Pacific Street entrance ramp to I-680 north opened.12

The cloverleaf interchange (Exit 3) joining Interstate 680 with West Dodge Road (U.S. 6) was rebuilt during a five year, $24 million project starting in July 2000. Exit 3 was redesigned to incorporate new directional ramps replacing loop ramps from I-680 north to U.S. 6 west and from U.S. 6 east to I-680 north. This work eventually ran in tandem with the ancillary project to build the West Dodge elevated expressway. The new ramp from I-680 to West Dodge Road opened to traffic on December 10, 2003.13 All work was completed at the West Dodge interchange by July 1, 2005.14

Two year widening of Interstate 680 was completed in November 2005 between West Maple Road (N-64) and Fort Street (Exit 5). Work expanded the freeway to six overall lanes.15

The $100 million West Dodge Expressway project, which added express lanes for U.S. 6 above W Dodge Road from 120th Street to I-680, started in Fall 2003. The westbound viaduct for U.S. 6 opened in July 2006, well ahead of the August 2007 scheduled completion. The eastbound elevated deck was ready for traffic in October 2006. All major work on the project was completed by mid July 2007.16

The 2007-2011 State Transportation Improvement Program for District Two called for expansion of 1.2 miles of I-680 from Fort Street north to Irvington Road to six overall lanes. This project joined a planned replacement of the Pacific Street bridge. The expansion project never went forward, but the $5.3 million project to replace the Pacific Street overpass across I-680 ran from May 2008 to August 22, 2008.17

Record flood levels along the Missouri River in 2011 submerged and irreparably damaged a 3.1 mile stretch of I-680 from the Missouri River to Interstate 29. An emergency repair project ensued in September 2011, with two contractors chosen with a winning bid of $19.2 million.18 The contractors beat the December 23rd deadline to have at least one lane of traffic in each direction open with the help of good weather and 14 hour workdays. The freeway reopened on November 2, 2011.19

Flooding from the Missouri River resulted in closures along I-680 and I-29 three separate times in 2019.
