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 402-399-1192 or contact katie.hatfieldedstrom@hdrinc.com 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.

Project update

Speed limit changes

In May, we expanded reduced speed limits around the Systems Interchange to support the ongoing construction efforts occurring in this area. View a map which illustrates where the speed limits were expanded locations throughout the project area. New signs are now in place.

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 are experiencing 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.


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.


Updated 3/25/2020: Beginning on March 20, 2020, the 380 Express bus is offering rides with no fare collections, until further notice. Each motor coach is cleaned and sanitized daily. During this time, they are asking riders to limit trips for essential purposes only.

380 Express Bus between Cedar Rapids and Iowa City is available for travelers in the area. Buses run regularly Monday through Friday. Buses are ADA compliant and feature free Wi-Fi. For rate and schedule details, visit 380express.com
