I-5 - 179th St. Interchange - Interchange Improvements

Project overview

This project aims to improve mobility for travelers who use the I-5 - Northeast 179th Street interchange. Signalized intersections will be removed and replaced with roundabouts at the on- and off-ramps to and from I-5. Roundabouts help to relieve congestion by keeping people moving safely through the intersection. This will make it safer and more accessible for people who walk, bike or roll through this area.

The project also includes replacing the I-5 bridges over Northeast 179th Street and addressing nearby fish barriers.

What to expect

Once the scope of the project is determined, the project will move onto the design phase, which is followed by construction. Traffic impact information will be developed during the design phase and provided when construction begins.

Originally built in the early 1960's, the Northeast 179th Street interchange is in need of upgrades and safety improvements to bring the interchange up to today’s design and safety standards. With anticipated growth in Clark County, the existing interchange configuration is not expected to be able to accommodate future traffic volumes.
