Construction Phase

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

Construction began in November 2019 to install new ODOT RealTime electronic signs on I-5 in North Portland from Marine Drive to I-405.​​​​​​​​


Traffic Impact

Saturday, December 7 to Saturday, December 14
  • Single lane closures on Mississippi Avenue under the I-5 at I-405 interchange with flaggers directing traffic weekdays 7 a.m. to 5 p.m.

POSTPONED: Full Ramp Closure of I-5 Northbound On-Ramp from N Alberta Street
The previously scheduled 24/7 closure of the I-5 northbound on-ramp from North Alberta Street from Dec. 8-15 has been postponed and will be rescheduled for mid-January.


The following ramp is currently scheduled for a 24/7 closure starting on Sunday, Jan. 5 at 9 p.m. until Sunday, Jan. 12 at 9 p.m.:

  • I-5 southbound off-ramp to N Alberta Street.

Specific dates and detour routes will be shared once construction schedules are confirmed.

For the most up to date traffic impacts, visit TripCheck or subscribe to ODOT Region 1 Weekly Construction Update​ emails.  The updates for this project can also be found in the weekly construction updates​ report.

All work requiring lane closures will be at night. Scheduled dates and times for specific lane and ramp closures are determined based on each site. Lane, ramp and full freeway closures related to construction will follow these general timeframes:
  • Single lane closures are allowed 8 p.m. to 5:30 a.m. (later on weekend mornings).
  • Double lane closures are allowed 10 p.m. to 5 a.m. (later on weekend mornings).
  • Full freeway closures are allowed midnight to 4:30 a.m. (later on weekend mornings).
  • Ramp closures are allowed 9 p.m. to 5 a.m. (later on weekend mornings).
More information about scheduled traffic impacts, detour routes and work hours will be posted here on the project website as the impacts are scheduled.

Construction Impacts

Construction will take place mostly at night to minimize traffic impacts during the day. Work began in November 2019 and will last through 2020. The schedule is subject to change based on weather and site conditions.
Nighttime construction noise will occur periodically from 6 p.m. to 7 a.m. and during the day. Those working or living in the area may hear the noise. Noise will come from heavy equipment, construction trucks, beeping noise when construction vehicles are in reverse (a requirement by the Occupational Safety and Health Administration), drilling, and other equipment such as compressors, pneumatic tools, generators, metal saws and drills. ODOT will apply construction noise mitigation measures to reduce noise impacts to surrounding neighbors. 
Call the 24/7 nighttime noise hotline to reach a live person to report any noise-related concerns at 971-673-5239.


​​Project design: through spring 2019.  Construction: Nov. 2019 through fall 2020.



The Oregon Department of Transportation began construction in Nov. 2019 to install new ODOT RealTime signs on I-5 which will help make roads safer and help drivers travel more efficiently by providing real-time traffic information.

New advisory speed signs, traveler information signs and relocated guide signs will be installed in seven locations along I-5 between Marine Drive and I-405. These signs w​ill assist in reducing crashes, improve travel time reliability, and enhance transit operations.

Site A: South of North Marine Drive. New electronic signs and new advisory speed signs will be installed. Site A will have northbound and southbound full nighttime closures. Nighttime northbound on-ramp closures at Victory Boulevard and Interstate Avenue.
Site B: Between North Victory Boulevard and North Schmeer Road. New advisory speed signs will be installed. Site B will have a southbound nighttime on-ramp closure at Victory Boulevard.
Site C: North of North Columbia Boulevard. New advisory speed signs will be installed. Site C will have northbound nighttime periodic lane closures.
Site D: North Bryant Street / North Saratoga Street. Pedestrian Bridge. New advisory speed signs will be installed. Site D. will have northbound nighttime on-ramp closure at Rosa Parks Way; southbound nighttime on-ramp closure at Lombard; and flagging at Bryant Street pedestrian bridge.
Site E: Between North Killingsworth Street and North Alberta Street. New electronic signs and new advisory speed signs will be installed. Site E will have northbound and southbound nighttime full closures; northbound on-ramp and southbound off-ramp closures at Alberta Street for seven days at a time.
Site F: North Skidmore Street Bridge. New advisory speed signs will be installed. Site F will have southbound nighttime on-ramp closures at North Alberta Street and North Going Street.
Site G: North Kerby Avenue to Interstate-405 Southbound on-ramp. New electronic signs and new advisory speed signs will be installed. Site G will have northbound and southbound nighttime full lane closures on Interstate-5 under the Kerby Avenue on-ramp; and a southbound nighttime on-ramp closure at North Greeley Avenue.
There are two nearby ODOT projects that may impact traffic along Interstate-5. These work areas include the Interstate Bridge project and the Interstate-405 Ramps project.
Construction for the Interstate Bridge project is expected to start in 2020. Learn more about construction of the Interstate Bridge Trunnion Project at
Construction for the Interstate-405 Ramps project will take place between 2019 and 2020. Learn more about construction for the I-405 Ramps Project at
