I-84 and I-5 Interchange Resurfacing

Construction Phase

Region 1: Portland metro and Hood River County (Portland , Multnomah )

Closures on the ramps that connect I-84 at I-5 will continue through January 2019 to extend the service life of the four ramps that connect the two interstates.​​ Get the dates, detour maps and learn more at our online open house.​


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.

Closure dates are posted on


While the new roadway is complete, there is more work to do. We are now working on installing new joint seals, barriers, fencing, and more. Our work has become less predictable as the weather has become cold and wet. Thank you for your ongoing patience as we continue our work on the ramps that connect I-84 and I-5.

We will see upcoming intermittent closures of the ramps that connect I-84 and I-5. Closures will occur during nights between 10pm and 5am and weekends between Fridays at 10pm and Mondays at 5am. The ramps that will see closures during these times include:

  • The ramp from southbound I-5 to eastbound I-84
  • The ramp from westbound I-84 to southbound I-5
  • The ramp from westbound I-84 to northbound I-5
    • The on-ramps to I-84 westbound at NE Sandy Blvd and NE 33 Avenue will be closed during these full weekend ramp closures.

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.
