The Oregon Department of Transportation (ODOT) alerts travelers that I-5 will close in both directions on up to four separate nights in November for installation of new RealTime signs.
The overnight closures will extend from the south Interstate 405 interchange to SW Terwilliger Boulevard, and the interstate will reopen at 5:00 a.m. the following mornings. The first closure, originally scheduled for the night of November 4, has been rescheduled for Thursday, November 6.
ODOT is installing RealTime variable advisory speed signs along this busy stretch of I-5 south of downtown Portland to improve safety and traffic flow by providing drivers with real-time traffic information.
I-5 Closure Schedule
- 11:00 p.m. Thursday, November 6, to 5:00 a.m. Friday, November 7.
- 11:00 p.m. Monday, November 10, to 5:00 a.m. Tuesday, November 11.Â
- 11:00 p.m. Thursday, November 13, to 5:00 a.m. Friday, November 14.Â

Detours
Detours signs will be set up before each 11 p.m. closure using these routes:
- Neighborhood traffic can detour using Barbur Boulevard.
- Regional traffic detours bypass I-5 in this section by using Interstate 205 to Interstate 84 or U.S. 26 to OR 217.
Expect delays and use caution when traveling in the area during these four nights. Also, expect lane closures before and after the nighttime full closure as crews set up and clean up the work site.
Dates may change due to weather or other unforeseen events.
Project Background
We are improving our RealTime system to make roads safer and help Oregonians get where they are going more efficiently by providing real-time traffic information to drivers.
The work includes installing RealTime Variable Advisory Speed (VAS) signs along a busy stretch of Interstate 5 south of downtown Portland from the Ross Island Bridge to Terwilliger Boulevard.
Work will finish in late 2025.
