I-80/I-380 construction

Attention icon

Due to COVID-19 we are asking visitors to not come to the I-80/I-380 Systems Interchange Project Office in Coralville to do business. Please call 319-499-6163 or contact Nicole.Schrobilgen@iowadot.us for assistance. If a trip to our facility cannot be avoided visitors will be asked a series of questions to evaluate their risk of exposure to COVID-19 and exposure to others in that facility before they are allowed to enter. Thank you for your understanding during this unprecedented time.

Current traffic impacts

It is anticipated that overnight closures will occur throughout the project. Detours will be posted, and notices provided, on 511ia.org. Emergency closures have occurred in the project area due to quick-forming pavement potholes and pavement settlement issues. Active emergency closures are posted to the 511ia.org. Please follow 511ia.org for the most current construction information and notifications.

Project update

I-80 EB to I-380 NB New Flyover Ramp Now Open

As of 12/23/2020

The I-80 eastbound to I-380 northbound Ramp is now open to drivers. This is a major milestone for the reconstruction effort on the Systems Interchange. Drivers can now expect to drive over an elevated bridge as they head north to I-380. Additionally, drivers on northbound U.S. 218 and I-380 will notice traffic shift to the left onto the newly completed pavement in the median. Traffic will be reduced to one lane. Drivers should anticipate delays in travel time.

Don’t forget that while the part of the project is now open, there is a lot more construction happening throughout the interchange. Help keep everyone safe by staying alert and paying attention to construction crews.

Speed limit changes

In May 2020, sections with reduced speed limit were expanded around the I-80/I-380 iinterchange to support the ongoing construction efforts in this area. View a map which illustrates the speed limits throughout the project area.

Traffic impacts and potential delays

For the best source and latest updates for traffic alerts and notifications, follow 511ia.org. Construction activities will have a greater impact on traffic in 2020 as all quadrants of the interchange will have active construction. Traffic impacts and potential delays due to construction may be experienced in the following areas:

  • Lane shifts are in place throughout the project, and additional new shifts are planned and should be expected.
  • 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 that has been added to help protect the public from construction activities and protect workers from traffic.
