Council Bluffs Interstate System (CBIS) for the Iowa Department of Transportation (IADOT)
The Council Bluffs Interstate System Improvement Program is an ongoing comprehensive interstate redesign project which will modernize the highway system and improve mobility and safety of approximately 18 miles of interstate running through the Council Buffs area in Iowa. It is the single largest project currently in the Iowa DOT's five-year Transportation Improvement Program. The program has and will be implemented in smaller, manageable projects ranging from $10M to $150M over time. These projects are prioritized by available funding and most significant impacts to traffic management, safety and vehicle capacity. The IADOT has partnered with the FHWA and HDR as the design consultant to expand the system to handle the 30 year traffic volumes estimated to run through I80 and I29. Improvements include updates to the lighting, traffic signal, ITS, guide signing, and related infrastructure.
