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.

To learn more about the I-80/I-380 Systems Interchange project, watch the video below.


Future I-80/I-380 Systems interchange

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 two 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.

Traffic impacts and potential delays

For up to date traffic alerts and notifications, follow 511ia.org. Traffic impacts and potential delays due to construction may be experienced in the following areas:

  • Overnight closures are anticipated throughout the winter for construction activities.
  • New traffic patterns along I-80, I-380 and U.S. 218 are in place. Lane shifts have been added throughout the system and will be in place. Drivers should be aware that in some areas, the shoulders have been eliminated due to the lane shifts and/or the addition of a temporary construction barrier rail has been added to help protect the public from construction activities and protect workers from traffic.
  • Traffic shifts to temporary shoulder pavement during construction on two ramps:  Eastbound I-80 to southbound U.S. 218 and westbound I-80 to northbound I-380.


It is anticipated that overnight closures will occur throughout the project. Detours will be posted and notices on 511ia.org. Please follow 511ia.org for the most current construction information and notifications.
