I-80/I-380 construction

Frequently Asked questions

WHAT IS THE I-80/I-380 SYSTEMS INTERCHANGE 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. The project is in Johnson County at the junction of Interstate 80 (I-80), Interstate 380 (I-380) and United States Highway 218 (U.S. 218). This important regional transportation hub is located within the cities of Coralville and Tiffin and serves the greater Iowa City metropolitan area. This project will reconstruct the interchange, and add lanes, allowing more vehicles to travel safely and reliably through the area. In advance of the I-80/I-380 project, a new interchange is being constructed on I-380 at Forevergreen Road, approximately 1.5 miles north of the I-80/I-380 interchange. The new Forevergreen Road interchange is scheduled for completion in fall 2019 and will help with traffic flow during and after the larger I-80/I-380 project.



WHERE IS THE PROJECT LOCATED?






WHAT IS THE PURPOSE OF THE I-80/I-380 SYSTEMS INTERCHANGE PROJECT?

This critical project will make it easier and safer for both commuters and freight haulers to travel to and through the area. The interchange is a major crossroads for the state of Iowa and the rest of the nation. As one of the busiest interchanges in the state, I-80/I-380 is a vital link in the state and nation’s overall connectivity, mobility, freight movement, and economic well-being. Installing new directional ramps will increase the safety and flow of traffic, replacing the current loop ramps that cause congestion and safety issues due to weaving traffic.



WHAT ARE THE BENEFITS OF I-80/I-380 SYSTEMS INTERCHANGE PROJECT?

Once the project is completed, we expect to see significantly fewer crashes, which means fewer injuries and fatalities. Over the next 30 years, models predict approximately 64 million fewer hours of traffic delays and the estimated typical trip will be 5-35 percent more reliable or more likely to arrive on time than is happening right now.



HOW CAN I LEARN MORE ABOUT PLANNED CONSTRUCTION IN MY AREA?

This website will provide up-to-date information about planned construction. As each component of the project progresses, the website, social media, and publications will provide regular construction updates.  We will hold public meetings to present details of the proposed improvements. Information presented at those meetings will be available on this website.



WHAT ARE THE OVERALL CONSTRUCTION PLANS FOR THE I-80/I-380 SYSTEMS INTERCHANGE?

I-80 will be widened to six lanes (plus auxiliary lanes) with full 12-foot shoulders through the study area. I-380 will be widened to six lanes for approximately four miles to approximately 2 miles north of the Forevergreen Road interchange. U.S. 218/Iowa 27 will be widened to six lanes from the interchange to approximately two miles south of I-80. These I-380/U.S. 218/Iowa 27 segments will also have full 12-foot shoulders. You’ll notice work starting in the area as soon as the fall 2018.



HOW WILL I KNOW ABOUT TRAFFIC IMPACTS IN MY AREA?

We invite you to use this website as the main information source related to the project. Please visit the site often to learn about changes or updates to the project design or schedule. If you have specific questions, please contact us. Log on to www.511ia.org or the 511 app to sign up for traffic alerts.



WHERE CAN I LEARN MORE ABOUT THE RIGHT OF WAY PROCESS?

For more information on the right of way process, please visit the Iowa DOT's Office of Right of Way website. You can also download the Iowa DOT's right of way brochure, "Highways and Your Land."



WHEN WILL CONSTRUCTION BEGIN?

Plans are to begin the main I-80/I-380 interchange reconstruction effort in the fall 2018, with construction continuing through 2024. Utility relocation and some smaller projects are in progress in 2017 and 2018. Final erosion control work may take place in 2025.



WHAT IS THE PURPOSE OF THE FOREVERGREEN ROAD INTERCHANGE PROJECT?

The Forevergreen Road interchange will reduce congestion at adjacent interchanges and allow for a turn-around detour during construction on the I-80/I-380 interchange while the northbound to westbound traffic movement is closed. Additionally, it will offer a link to a temporary diversion route in case of emergency.



HOW LONG WILL CONSTRUCTION TAKE PLACE?

Traffic impacts due to construction of the I-80/I-380 interchange is expected to continue through the 2024 construction season. Minor touch-up and erosion control work may continue in 2025.



IF I OWN A BUSINESS IN THE PROJECT AREA, HOW CAN I STAY INFORMED?

We understand that this interchange is a primary gateway from the west for the Iowa City area and from the south for Cedar Rapids. The interchange provides direct access between two significant job markets. Nearly 18,000 Johnson and Linn county residents live in one county and work in the other, and an estimated 35,000 daily trips are taken between Iowa City and Cedar Rapids for school, shopping, and recreation. Additionally, this interchange is often traveled by visitors, students, and patients of the University of Iowa Hospitals and Clinics. We are committed to minimizing the impact to travelers and local businesses. Business tool kits have been developed to provide materials and information to interested businesses. If you are interested in receiving a business tool kit, please contact us.
