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. Construction is expected to be complete in fall 2024.

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 for approximately four miles north of I-80 to approximately 2 miles north of the Forevergreen Road Interchange. U.S. 218/IA 27 will be widened to six lanes to approximately two miles south of I-80. Additionally, auxiliary lanes will be included in some areas between interchange ramps. This will provide drivers more time to merge in or out of interstate traffic. The current loop ramps, which cause congestion and safety issues due to weaving traffic, will be replaced by directional ramps.

During fall 2018, major construction efforts begin - mostly off the existing roadway. It is important to note that some overnight ramp closures are anticipated. Follow 511ia.org to stay up to date with construction and traffic news.
