West System Interchange

Project Location

Council Bluffs, IA

Project Description

Reconstruction of the West System Interchange provides for efficient and safe vehicle movement on both I-29 and I-80 systems. The left-hand entrance and exit from I-29 to I-80 were eliminated as part of the reconstruction. An increase in the number of travel lanes for both I-80 and I-29 allows motorists to reduce the number of lane changes needed between I-80 and I-29.

The project included full reconstruction of this system to system interchange, providing full access from I-80 and I-29 to the I-80 express lanes and the I-29/I-80 local lanes in the Dual, Divided Freeway. The West System Interchange reconstruction projects are located approximately one-half mile east of the Missouri River where I-80 intersects I-29 near the Western Historic Trails Center in Council Bluffs.

The West System Interchange was fully completed and opened to traffic in 2019.
