Region 1 Construction 2018


Construction Project List

I-5: Columbia River to Moda Center
Once complete, this project will pave 6 miles of I-5, including some ramps, between the Interstate Bridge and Moda Center, improve sidewalks and curb ramps, replace median barriers and upgrade signs.
  •   Night lane closures and ramp closures: Summer 2018 to spring 2019.

I-5 at I-84
This project will repair and resurface the bridges that connect I-84 and I-5. While the new roadway is complete, there is more work to do. We are now working on testing to ensure bridge joints are operating properly, a regular check after bridge joint installation. 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 the full weekend ramp closures of westbound I-84 to northbound I-5.
Accommodations in the schedule will be made for large public events such as Race For A Cure and Portlandathon.

I-84 (102nd to 148th)
This project installed, replaced, repaired and upgraded existing interstate signs between NE 102nd and 148th Avenues. The work required full closures of I-84 between NE 122nd Ave. and NE 181st Ave. nightly until Aug. 30. The project is now complete.
