West System Interchange

Project Location

Council Bluffs, IA

Project Description

Reconstruction of the West System Interchange will provide 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 will be eliminated as part of the reconstruction. An increase in the number of travel lanes for both I-80 and I-29 will allow motorists to reduce the number of lane changes needed between I-80 and I-29.

The project includes 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.

Project UpdateS

In fall 2014, the program reached an important milestone in opening the new I-29 southbound  and northbound ramps in the West System Interchange. To view the new traffic configuration, click here.

Phase II construction of the West System Interchange began in summer 2015. This phase of construction will construct the westbound I-80 express lanes from the Missouri River to just east of Indian Creek and the I-29 northbound/I-80 local ramp to I-29 northbound. This phase of construction is expected to be complete in 2017.
