Interstate 680 Nebraska / Iowa

East End
South End
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 full cloverleaf interchange with I-29 and County Road G37 outside the city of Crescent. I-680 combines with Interstate 29 north parallel to the Missouri and Boyer Rivers to Loveland, where I-680 branches eastward across the Loess Hills. A vista point lies along the scenic and lightly traveled freeway taking I-680 back 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 includes the removal of I-680 from the nearly ten 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.

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 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 is now Interstate 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 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).

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 (West 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 extended 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 on-ramp to I-680 north opened.12

The full 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 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.

Interstate 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 $100 million West Dodge Expressway project, which added express lanes for U.S. 6 above West 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.

Perspective from Interstate 80 east
Entering the directional T interchange with Interstate 680 on Interstate 80 east. Note the sign error where the I-80 mainline was also signed as Exit 27.
Sign changes made by 2011 greened out North Omaha and replaced the exit tab for I-680 west. The exit tab on the pull through panel remained.
Clearview sign panels installed by 2014 restored North Omaha while adding a LEFT exit tab for I-680. The erroneous tab to the right was also finally dropped. Photo taken by Dale Sanderson (2001).
Historic Perspectives from Iowa 191 and Pottawattamie County Road G8L
Approaching the easternmost mainline interchange of Interstate 680 along County Road G8L (Railroad Highway) north. Signs here previously referenced I-80 for the eastbound on-ramp. All stand alone shields were replaced by 2014 with small guide signs. I-680 is referenced solely with the change. Photo taken by Jeff Morrison (06/09/03).
Between Jan. 1, 1969 and July 1, 2003, Iowa 191 paralleled Interstate 80’s diagonal southwest from Neola to Council Bluffs. Today it ends at Exit 28 of Interstate 680. This sign assembly previously directed motorists onto the westbound on-ramp to north Omaha and the former continuation of IA 191 south. It was replaced with an end shield by July 2005. Photo taken by Jeff Morrison (06/09/03).

South End I-80 – Omaha, Nebraska

Perspective from Interstate 680 south
A two lane collector distributor roadway branches away from the southbound mainline at Exit 1 for West Center Road (former Nebraska 38). The c/d roadway continues south to provide access to the local lanes of I-80 west for I Street, U.S. 275 & Nebraska 92 (L Street) and Q Street. The ramp from I-680 south to I-80 west bypasses all local exits to Giles Road (Exit 442). Photo taken 03/30/16.
The c/d roadways bring Interstate 680 up to 11 overall lanes as the freeway passes through the parclo interchange (Exit 1) with West Center Road (former Nebraska 38). The freeway mainline splits in one half mile for Interstate 80. Photo taken 03/29/16.
The two left lanes connect to Interstate 80 east, while the two right lanes connect to Interstate 80 west (signed as Exit 446 based upon the I-80 mileage). The connection from southbound Interstate 680 to eastbound Interstate 80 is part of a commuting pattern to downtown Omaha. Photo taken 03/29/16.
The Exit 1 c/d roadway partitions into a two lane ramp for I-80 west to U.S. 275 & NE 92 for Westwood Heights and Old Millard East and a single lane connection to I-80 east toward the Westgate Area and Downtown. Photo taken 03/30/16.
Typical of Nebraska and Iowa signing practices, an end panel appears as Interstate 680 enters the three wye interchange with I-80. The transition to westbound Interstate 80 is part of the bypass route around Council Bluffs and central Omaha. Photo taken 03/29/16.
The c/d roadway partitions for Interstates 80 east and west. Construction underway in 2015 and 2016 resulted in ramp closures as NDOR rebuilt some of the ramps between the two freeways. Photo taken 03/30/16.
Historic Perspective from Interstate 680 south
Replaced guide signs for I-680 south at Exit 1. The shield for Nebraska 38 was greened out, as it was decommissioned on January 1, 2003. The c/d roadway for Exit 1 continues to parallel Interstate 680 before merging onto the westbound I-80 c/d roadway that connects to U.S. 275 & Nebraska 92 and the alphabet streets. So in essence, Exit 1 also provides a connection to Interstate 80, while the main lanes are the direct bypass route. Photo taken 09/05/05.
Separate panels for Interstate 80 east and Exit 446 for I-80 west were replaced with a diagrammatic sign by 2007. Photo taken 09/05/05.
11 lanes of traffic run between Exit 1 with West Center Road and Interstate 80 (Exit 446). Signs here were also replaced with a single diagrammatic sign by 2007. Photo taken 09/05/05.

Five lanes of Interstate 80 west advance toward the three wye interchange (Exit 446) with Interstate 680 north. A collector distributor roadway (Exit 445) departs prior to the mainline I-680 off-ramp (Exit 446) for the subsequent three exits of I-80 west to I Street, U.S. 275 & NE 92 (L Street) and Q Street). Photo taken 06/18/15.
South 96th Street spans Interstate 80 west a half mile ahead of the separation with the Exit 445 c/d roadway. Exit 445 also connects with the local lanes of I-680 north to the adjacent West Center Road (former Nebraska 38) interchange (Exit 1). Photo taken 06/18/15.
Interstate 680 travels north to serve as the western and northern bypass of Omaha. However, it is also a conduit for the growing western suburbs in conjunction with the booming corridor along U.S. 6 and the West Dodge Expressway. Photo taken 06/18/15.
Two lanes partition from I-80 west for the c/d roadways running north to West Center Road and southwest to I-L-Q Streets. The additional roadways along both I-80 and I-680 were added during construction from spring 1994 to December 1997 to better separate local and through traffic movements. Photo taken 06/18/15.
Three lanes follow onto the Interstate 680 mainline (Exit 446), which bypasses West Center Road (old Nebraska 38) to Pacific Street and the West Dodge Expressway (U.S. 6) leading to Elkhorn and Fremont. Photo taken 06/18/15.
