The CBIS improvements project is a major effort focused on improving Interstates 80, 29 and 480 within the Council Bluffs metropolitan area. The CBIS improvements project is intended to improve mobility through the region by upgrading the I-80 and I-29 corridors, improving the condition of the roadways, reducing traffic congestion and crashes, and adding capacity. Approximately 18 miles of mainline interstate (I-80, I-29 and I-480) and 14 interchanges (three interstate-to-interstate interchanges and 11 interstate-to-local street interchanges) are included in the study area.
Council Bluffs interstate system
The interstate system in Council Bluffs typically carries 20,000-75,000 vehicles daily, with 11-25 percent of those vehicles being trucks. On some areas of I-80 more than twice the number of vehicles use it compared to the traffic volume estimate used during the original design. By 2030 traffic on I-80 between the I-29 interchanges is expected to increase to over 120,000 vehicles a day. Currently, traffic on I-29 north and south of I-80 averages 20,000 vehicles per day, and that number is expected to at least double by 2030. View the complete CBIS project overview.
Environmental studies
Solutions for the Council Bluffs interstate system will balance engineering requirements with environmental and community issues. Federal, state and local environmental legislation and procedures will guide the evaluation of possible solutions. Examine the environmental studies associated with this project.

The Iowa Department of Transportation (Iowa DOT) recognizes that the Council Bluffs Interstate System (CBIS) improvements project will change the look of the interstate system and the entrance to Council Bluffs, Iowa. Project plans will include limited aesthetic treatments and enhancements. To develop a vision for the aesthetic treatments and enhancements, the Iowa DOT created an Aesthetic Subcommittee made up of community members to assist in developing a plan for the project. The subcommittee helped develop an Aesthetics Master Plan for the interstate corridor that incorporates local culture, landscape and other planning initiatives to create a cohesive interstate corridor that is attractive and easy to navigate for daily commuters as well as first time visitors. View feature projects and the project master plan.
Public meetings will be held for the Council Bluffs Interstate System (CBIS) improvements throughout the project development process. The meetings provide opportunities to review the progress of the project, ask questions of the project team and are a great way for the public to stay informed.
