Construction Impacts

Thank you for your patience throughout the closures of the ramps that connect I-84 and I-5. 
The two-week closures are complete and we have closures that will occur on nights and weekends through January 2019.


We have worked to accommodate large public events such as Race For A Cure and Portlandathon.

Cost and Funding



Night and weekend closures of the ramps that connect I-84 at I-5 continue through January to extend the service life of the four ramps that connect the two interstates. Three ramps are in need of structural repair and structural resurfacing. One of the ramps only requires surface repairs.

What Problem Will This Improve?

An average of ​147,000 vehicles pass through the I-84 and I-5 interchange on a daily basis. The concrete ramps that carry this traffic are showing wear and tear. Work includes replacing bridge joints, performing structural​ repairs and resurfacing. Without these repairs, the ramps would need to close to trucks or other heavy vehicles and could eventually stop serving all drivers.
