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 now complete and we have some  closures that will occur on nights and some weekends through November 2018.


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

Closure dates are posted on


Construction June - December 2018
Here is the schedule through Oct. 15:
  • The ramp from northbound I-5 to eastbound I-84 will see one nighttime closure from 10pm Sept. 17 to 5am Sept. 18.

Cost and Funding



Night and weekend closures of the ramps that connect I-84 at I-5 start September 4 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.
