Plan ahead for nighttime detours on Interstate 5 in the Portland metro area during the next two weeks while we replace three variable message signs.
Closure schedule:
- Northbound I-5 in Wilsonville, 1-4 a.m. Thursday and Friday, Nov. 5-6.
- Southbound I-5 in Tigard, 1-4 a.m. Monday and Tuesday, Nov. 9-10.
- Northbound I-5 in North Portland, 1-4 a.m. Wednesday and Thursday, Nov. 11-12.
Signed detours will be in place during each closure – detour maps and details are below.
We are replacing and upgrading equipment that is beyond its service life in the Portland area. Improvements include replacing variable message signs, improving sign structures, and restriping. This work helps us maintain operations of the transportation system and supports a smoother and safer ride for travelers.
Variable message signs carry messages for traveler safety and travel information – including traffic impacts such as crashes and closures, road conditions and Amber Alerts. For more information, visit the project page.
Check Tripcheck.com before you travel. We updated it with the latest information on traffic impacts from construction, maintenance, crashes and other incidents. Scheduled work is sometimes postponed due to weather and other factors.
