Construction Phase

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

24-hour a day closures lasting up to two weeks on the bridges that connect I-84 at I-5 start July 8 to extend the service life of the three bridges that connect the two interstates.​ Get the dates, detour maps and learn more at our online open house.​


Construction Impacts

​This work will require closures around-the-clock, meaning 24 hours a day, for two weeks of three of the bridges that connect I-84 and I-5 in July and August 2018.  Only one bridge will close at a time. 

In addition to the two-week closures, overnight ramp closures could occur nightly from 10 p.m. to 5 a.m. through November 2018. More details will be available as construction progresses. 

The bridge that connects I-5 northbound to I-84 eastbound will only require nighttime closures. Closure dates are posted on

Cost and Funding



​24-hour a day closures lasting up to two weeks on the bridges that connect I-84 at I-5 start July 8 to extend the service life of the three bridges that connect the two interstates. Three bridges are in need of structural repair and structural resurfacing. One of the bridges only require 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 bridges that carry this traffic are showing wear and tear. Work includes replacing bridge joints, performing structural​ repairs and resurfacing. Without these repairs, the bridges would need to close to trucks or other heavy vehicles and could eventually stop serving all drivers.
