I-80 East/I-29 Overpass Opening

On a daily basis, the Council Bluffs Interstate System typically carries 20,000-75,000 vehicles; 11-25 percent of those are trucks. By 2030, traffic on I-80 between the I-29 interchanges is expected to increase to more than 120,000 vehicles a day. This increase in traffic, coupled with an outdated design standard from the 1950s and 60s is driving the acceleration of the system improvements.

The Council Bluffs Interstate System Improvement Program is a major effort that will result in a modernization and reconstruction of the interstate highway system in the Council Bluffs metropolitan area.

Iowa DOT is committed to completing the interstate improvements with minimal inconvenience to the public. Additionally, we are committed to keeping the traveling public informed of the project impacts in a timely and accurate manner. Sign-up for mobile alerts and traffic information.

The Program team has divided the interstate improvements into a variety of different project areas. The maps below show these project areas and provide approximate start and finish dates for construction. In order to expedite the construction schedule while minimizing impacts to interstate travelers, multiple construction projects will be active at the same time. Motorists will also see construction activity in many areas paused while other areas are improved before construction picks up again.
