Portland Prepares for Five-Week Southbound I-5 Closure in Rose Quarter
9/5/2026, 9:12:26 PM
Closure Timeline and Scope
All southbound lanes of Interstate 5 through Portland’s Rose Quarter are scheduled to close at 10 p.m. on September 11 and remain shut until October 17. The shutdown covers the segment between I-84 and I-405 and will last for five weeks.
Repair Work and Safety Goals
The Oregon Department of Transportation (ODOT) says the closure is needed for “critical repairs and safety improvements.” Work will include removing the existing concrete surface, repairing bridge joints, repaving, repainting lane lines, and reinforcing weak areas. ODOT notes the concrete on the elevated structure was last replaced in 1985, and the project will also continue seismic upgrades that began in fall 2025. The Portland Bureau of Transportation (PBOT) recommends drivers use alternate routes such as the Morrison Bridge, Steel Bridge, N Greeley Avenue, N Interstate Avenue, N Mississippi Avenue, N Vancouver Avenue, N/NE Broadway, NE 15th Avenue, NE 33rd Avenue, and NE Martin Luther King Jr Boulevard, while warning that these streets will also experience added congestion.
Projected Traffic Congestion
Officials warned that commute times could triple during the closure. Peak travel periods are expected between 6:30 a.m. – 9:00 a.m. and 4:00 p.m. – 8:30 p.m., with the greatest impact anticipated when commuters return to work. Transportation officials are urging drivers to leave earlier, consider teleworking where possible, and make room for ambulances, fire engines, and other emergency vehicles traveling near Legacy Emanuel Medical Center.
Commuter Concerns
Local drivers expressed frustration about the anticipated gridlock. Brian Thompson, a Portland commuter, said the closure could extend his drive from 20 minutes to an hour. He also described the situation as “utter gridlock” and noted the difficulty of planning around the disruption while juggling school pickups, grocery trips, and work. Another driver, Jerry Ware, said families may need to leave 20 minutes earlier each morning for five weeks.
