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 1 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. I-80 will be widened to 8 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.

 

 

DESIGN ELEMENTS

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.

Project update

As of 6/19/2019

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:

  • NEW! Kansas Avenue Relocation – Kansas Avenue southwest has been relocated to south of the previous location to make room for two new ramps on the 80/380 Systems Interchange. While the road is no longer closed to the traveling public, roadwork continues and drivers are reminded to stay alert and be cautious while driving through the construction zone.
  • Traffic will shift lanes on eastbound I-80 during various bridge widening and construction work in 2019.
  • 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.
  • Refer to the Forevergreen Road project page for Forevergreen Road updates.
