Nighttime ramp closures (10 p.m. to 5 a.m.) the week of Aug. 20:
** August 20, 21, 22, 23, 24 – Lower Boones Ferry off-ramp from I-5 northbound
** August 20, 21, 22 – Nyberg Street on-ramps (from both directions) to I-5 northbound
** August 21, 22 – Caman Drive off-ramp from I-5 northbound
** August 21, 22 – Lower Boones Ferry on-ramp to I-5 northbound
This project began construction in February 2018. Read the February 2018 fact sheet
for more information. Travelers should expect the following impacts:
- During daytime hours, travel lanes on I-5 will remain open. The lanes on I-5 will be shifted to make room for staging areas. People will see construction along the highway, day and night
- Nighttime lane closures on I-5 will begin as early as 8 p.m.
- There will be reduced parking at Trimet's Tualatin Park and Ride at SW 72nd & Bridgeport Road.
- There will be intermittent night and weekend ramp lane closures
- Expect two consecutive full weekend closures of the Lower Boones Ferry Road southbound on-ramp in summer 2018. Closures will occur from Friday at 10 p.m. to Monday at 5 a.m.
- Expect one full weekend closure of the Lower Boones Ferry Road northbound off-ramp in either summer 2018 or summer 2019 (but not during the same weekend as the on-ramp closures). Closure will occur from Friday at 10 p.m. to Monday at 5 a.m.
- We will provide advance notice of weekend closures when they are known. Check here for up-to-date information
- The speed limit will be posted at 55 MPH throughout the construction area. A 45 MPH speed limit is in effect through areas where construction work is actively occurring and workers and equipment are not protected by barrier.
- There will be a sidewalk closure at the Lower Boones Ferry Road southbound on-ramp during construction, starting in February 2018. A pedestrian detour will be in place
Residences and businesses adjacent to the project area may hear construction noise, during the day and night. ODOT has obtained required noise variances in order to complete the work. ODOT and the contractor will work to minimize the noise as much as possible, but there will be unavoidable noise including back-up alarms. Call the 24-hour noise hotline for noise concerns at 971-673-5239.
Q: Is the Sagert Street overpass flagging related to this project?
A: No. The week of Aug. 6, 2018, an over-height vehicle hit the Sagert Street overpass while traveling on I-5. The bridge sustained damage and is need of emergency repair. Until the repair is complete, the weight on the bridge must be reduced. This will be accomplished by only allowing one direction of travel at a time.
Flaggers will be controlling one-way traffic on the bridge 24/7 for the next two months until the repair is complete. We are encouraging drivers to take alternate routes. The bike lanes will remain open in both directions.
Q: Is the 45 MPH speed limit in effect 24/7?
A: No. To keep workers safe during construction, a new speed zone order will reduce the posted speed limit from 55 MPH to 45 MPH through fall 2018. Speed reductions are in effect through areas where construction work is occurring and workers and equipment are not protected by barrier. When work is not occuring or it's behind concrete barriers, the speed limit will be 55 MPH.
Q: Why is there construction in the I-5/I-205 interchange?
A: The area in the I-5/I-205 interchange is being used to store the contaminated soil that is excavated from the areas north. The top 18 inches of soil is contaminated with lead, and all that contaminated soil has to be put somewhere differently than the clean soil beneath it. There will be trucks in and out of that area over the next several months delivering the contaminated soil.
