DesignDue to the magnitude of the improvements needed for the Council Bluffs interstate system, the project will be implemented in smaller, manageable segments over time. Boundaries were established in Tier 1 to divide the system into five segments with logical ending points that could be designed and built independent of adjacent segments.
Select a segment from the map below for detailed information.
Multiple preliminary alternatives have been developed for all five segments and the preferred alternative has been identified for Segments 1, 2 and 3. Additional engineering and environmental studies are underway for each of these segments in Tier 2. Tier 2 studies for Segments 4 and 5 will begin at a later time.
