Commuter At-a-Glance Traffic Impact Forecast

Commuter Map

Travel Times: Travel times for the I-380/U.S. 218 corridor and I-80 in the project area are displayed on message boards to give motorists a clearer picture of traffic impacts they may encounter. Travel times will be shown during peak morning and evening rush hours.

Inclement Weather Driving: In the Midwest, the weather is unpredictable. What we can predict is that when weather is inclement, we need to continue to be extra cautious when driving through the construction work zone. Remember to adjust your driving accordingly and allow for extra travel time in case of potential delays.

Speed limit reduction: The speed limit on westbound I-80 in the Coralville area has been reduced to 55 MPH. Speed limits on I-380 and eastbound I-80 were also reduced to 55 MPH. Traffic speeds may be further reduced as part of traffic staging and traffic shifts. Pay attention to posted speed limits and stay alert. Be prepared for changes in lanes and traffic patterns, and pay attention to signs and other work zone alerts to keep you and our workers safe. View a map which illustrates the speed limits throughout the project area.

During reconstruction of the I-80/I-380 Systems Interchange, ongoing construction activities will continue to impact drivers throughout the system. Drivers should refer to for more information and anticipate the following changes in travel:

  • Lane Shifts: New traffic patterns along I-80, I-380 and U.S. 218 are in place. Lane shifts have been added throughout the project. New lane shifts and other traffic pattern changes will occur through 2022. 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.
  • Nighttime Lane Closures: Nighttime, single lane closures and full closures are expected in the project area through 2022.
  • Overnight Road/Ramp Closures: Overnight ramp and road closures are planned through 2022. At times there are multiple closures occurring at the same time on the interchange.
  • Long-term/Permanent Ramp Closures: As the redesigned interchange continues to take shape, existing ramps will begin to close for longer stretches of time. Some will close permanently and will be replaced with new ramps.
