Design Overview Video

The Council Bluffs Interstate System Improvement Program is a comprehensive interstate redesign that will modernize the highway system and improve mobility and safety of approximately 18 miles of interstate. It is one of the state's largest projects currently in the Iowa DOT's five-year Transportation Improvement Program. The program will be implemented in smaller, manageable projects over time. These projects are prioritized by available funding and most significant impacts to traffic management, safety, and vehicle capacity.

The map and video below give an overview of the program's proposed design. It highlights improvements to pavement and bridges and also shows areas where the railroad was removed and relocated. Descriptions of these projects can be found in the Projects section.

The Iowa DOT understands the Council Bluffs Interstate System Improvement Program will change the look of the interstate system and the Council Bluffs entrance into Iowa. As such, the DOT plans to address aesthetics throughout the project. An Aesthetics Subcommittee, composed of community members, Iowa DOT, and consultants, was created to help develop a vision for the aesthetic treatments and enhancements. An Aesthetics Master Plan was developed for the interstate corridor that incorporates local culture, landscape, and other planning initiatives to help ensure a cohesive interstate corridor that is attractive and easy to navigate for the traveling public.

Because of the many transportation needs across the state and limited funding, the level of enhancements for the Council Bluffs corridor will depend on state and local partnerships to provide additional funding contributions for the enhancements.

Possible aesthetic improvements and opportunities include bridges, landscaping, community gateways, lighting, retaining walls, public art, vehicle barriers and fencing.
