I-5 SW Portland Bridge and Ramp Improvements

Other

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


​​​​​​​​​​Oregon Department of Transportation (ODOT) is currently designing projects to improve the I-5 bridge at SW 26th Avenue and repair three ramps that access I-5 in SW Portland. These structural improvements will maintain and extend the life of our roadway system and give travelers a smoother ride.


Impacts

Traffic Impact

Saturday, Oct. 9 — Saturday, Oct. 16, 2021

​35-day ramp closure continues until Thursday, Oct. 14: The Capitol Highway on-ramp to I-5 south will be closed 24/7 for five weeks (35 days) beginning at 12:01 a.m. Thursday, September 9 and ending at 5 a.m. Thursday, October 14. The project is on-track to finish on time.
  • The ramp will be closed for 35 consecutive days so that workers can replace the concrete bridge deck and install new ramp joints and bridge rails. Travelers should follow posted detours and expect traffic delays and commute impacts.
  • Right lane closure on southbound Barbur Boulevard: ​the right lane of southbound Barbur will be closed between Taylors Ferry Road and Capitol Highway during the 35-day ramp closure, but the driveways around Barbur World Foods will remain open.
  • There may be intermittent nighttime lane closures on I-5 south at Capitol Highway.
Nighttime lane closures on I-5 and SW Barbur Blvd​: Work begins this week on the Barbur Boulevard on-ramp bridge and will continue for 3-5 months.
  • Workers will first remove old paint from the steel structure of this bridge, then repaint it and replace bolts as necessary.
  • Most traffic impacts will be on I-5 and not the Barbur ramp itself, with some nighttime single lane closures. We expect work to be complete in spring 2022.
  • ​Expect periodic construction noise during the first phase of the project, mostly from heavy equipment and construction trucks (example: required vehicle reverse noises) and the sandblasting process required to remove the old paint. Those working or living near the work areas may hear construction noise between the hours of 8 p.m. to 5 a.m.
  • ODOT will use construction noise mitigation measures to reduce noise impacts to surrounding neighbors. Use the 24/7 nighttime noise hotline to reach a live person to discuss any noise concerns: 503-276-7811.

Benefits

  • Maintaining and investing in our roads: This work will extend the life of the transportation system. Ramp repairs increase capacity to handle daily traffic loads, while a bridge improvement will better sustain a major event, such as an earthquake. 
  • Smoother ride for travelers: An improved roadway will provide a smoother ride for 120,000 drivers who use this stretch of I-5 every day, causing less wear and tear on drivers’ vehicles.
What Project Will This Improve?

This project will address one bridge and three ramps in need of improvement to provide a smooth ride for travelers, extend the life of the heavily traveled roadway, and maintain safe conditions.
