The East System Interchange project will address capacity needs, improve safety, and correct functional design issues associated with this interchange and the South Expressway/IA 192 interchange.
The East System Interchange includes the area of I-80 immediately east of Indian Creek (including the South Expressway/IA 192 interchange) and continues to a point southwest of the Madison Avenue and I-80 interchange. The area also includes I-29 from north of the U.S. 275/IA 92 interchange to Indian Creek.

Reconstruction of the East System Interchange will include straightening I-80 through the interchange. The new interchange will improve efficiency by eliminating left entrances and exits and allowing highway users to move through the area with fewer lane changes. The South Expressway/IA 192 interchange will be constructed with the East System Interchange reconstruction. The folded diamond interchange will be rebuilt to meet current design standards and capacity needs. The reconstructed interchange will be similar to the existing interchange configuration with two loop ramps and two diagonal ramps west of South Expressway/IA 192. The rail line east of South Expressway/IA 192 will be decommissioned with the railroad relocation and consolidation efforts, further improving traffic operations and safety at the interchange.

• Construction scheduled to occur between Jul 2013 and Sep 2019.
