Construction Updates for the Week of Saturday, October 13 - Friday, October 19th
Friday, October 12th: Scheduling problems have forced
a delay in the planned Friday night closure of all lanes of I-5 southbound at
SW Nyberg Street (milepost 289) to install two sign bridges. We’ll let travelers know when a
new date has been set for the needed work.
Saturday, October 13th: Southbound and northbound I-5 will be closed at Lower Boones Ferry Road from 11 p.m. to 6 a.m. All
traffic in both directions will be detoured off at Lower Boones Ferry Road and will
be directed to re-enter the freeway via the Lower Boones Ferry on-ramp.
The following southbound ramps will be closed at night next week:
- Exit 291 toward Carman Drive
- Exit 290 toward Lower Boones Ferry
- Exit 289 on-ramp toward Nyberg Street
- Ramp from I-5 south to I-205
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 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 throughout construction. 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: What's happening on the Sagert Street overpass? Is it related to this construction 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 in need of emergency repair. The repairs are going on now and will continue for a few more months.
Initially, there was 24/7 flagging on the bridge. A recent analysis showed that two-way traffic can be supported on the bridge, so the round-the-clock flagging was lifted.
Most work on the bridge will happen at night. During the night work, there will be one-way flagging on the bridge. Bike lanes will remain open in both directions during the nighttime flagging.
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 different 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.
