I-80/I-380 construction

About the project

The I-80/I-380 Systems Interchange Project is a comprehensive redesign that will improve travel in the area, making it easier and safer to get where you’re going. This project is one of our top priorities.


The reconstruction project will replace all four loops of the interchange with directional ramps. Interstate 380 will be widened to six lanes with 12-foot shoulders from I-80, to approximately one mile north of the Forevergreen Road interchange. U.S. 218/IA 27 will be widened to six lanes from I-80 to approximately 1.5 miles south of I-80. Interstate 80 will be widened to six lanes with 12-foot shoulders between Ireland Avenue and I-380. Interstate 80 will be widened to eight lanes from near I-380, east to near Coral Ridge Avenue. Additionally, auxiliary lanes will be included in some areas between interchange ramps to provide drivers more time to merge in or out of interstate traffic.

The map below shows the new design for the Systems Interchange. Roadways are shown in orange and bridges are shown in blue.


The aesthetics and pier shapes were determined through a series of meetings with agencies and the public. Pier Shape Option A (shown) was selected, and features limestone texture and color treatments that will complement concrete barrier rail design present along I-80 through the Iowa City and Coralville metro area.
