Project Details

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 in order 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 now have closures that will occur at night to put the finishing touches on the work.


Closure dates are posted on


We have successfully flood tested 58 total joints on the I-5 and I-84 interchange ramps and they have all passed inspection. This is a significant milestone in our work on the interchange ramps.
We still need to apply a deck seal to the ramps. All ramps will need to be sealed in the coming months. The I-5 northbound to I-84 eastbound ramp has already been sealed. This leaves the remaining three ramps to be sealed.
  • 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
Here is the up-to-date closure schedule:
  • The ramp from I-84 westbound to I-5 southbound will experience full nighttime closures during these times:
    • Tuesday, September 3, beginning at 10pm, continuing until 5am Wednesday 
    • Wednesday, September 4, beginning at 10pm, continuing until 5am Thursday
    • ​Thursday, September 5, beginning at 10pm, continuing until 5am Friday
  • The ramp from I-5 southbound to I-84 eastbound will experience will experience full nighttime closures during September 2019. We will announce the exact dates soon.
  • The ramp from I-84 westbound to I-5 northbound will experience full nighttime closures during September 2019. We will announce the exact dates soon.

Cost and Funding



Night and weekend closures of the ramps that connect I-84 at I-5 continue. The work being done extends the service life of the four ramps that connect the two interstates. Three ramps were in need of structural repair and structural resurfacing. One of the ramps only required 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 were showing wear and tear. The work included replacing bridge joints, performing structural​ repairs and resurfacing. Without these repairs, the ramps would have needed to close to trucks or other heavy vehicles and could have eventually stopped serving all drivers.
