Nighttime Lane Closures Scheduled for I-205 and I-5 as Holiday Commute Remains Light

Holiday Traffic Outlook

Today, Monday, January 19, 2026, marks Martin Luther King Jr. Day. Commuters in the Portland metropolitan area can expect significantly lighter traffic during the traditional morning and afternoon rush hours as most city, state, and federal offices are closed. However, those traveling later in the evening or utilizing key interchanges should be prepared for scheduled construction impacts and significant roadworks.

Major Roadworks and Arterial Impacts

• I-205 Abernethy Bridge: The multi-year I-205 Improvements Project continues with active work today. Drivers should prepare for a daytime northbound lane closure at the OR 43 roundabout from 9:00 AM to 3:00 PM. While the roundabout will remain open, minor delays are expected. Heavier impacts begin tonight at 10:00 PM with scheduled lane closures on both I-205 northbound and southbound between West Linn and Oregon City.
• I-5 Rose Quarter: Central city travelers will encounter overnight fast lane closures in both directions between the Oregon Convention Center and the Burnside Bridge starting at 10:00 PM. This is part of the ongoing Rose Quarter Improvement Project to install new barrier structures and stormwater facilities.
• I-5 Southbound Width Restrictions: South of downtown, a section of I-5 southbound near the Ross Island Bridge (MP 301.98 to 301.49) remains restricted to a width of 14 feet 5 inches during nightly work hours (10:00 PM to 5:00 AM). Drivers of oversized vehicles are advised to coordinate with the permit unit.
• Surface Street Alerts: Expect nighttime flagging on Clackamette Drive and lane closures on OR 99E under the I-205 bridge starting at 8:00 PM. Additionally, the ramp from OR 43 to I-205 northbound will be closed from 10:00 PM to 5:00 AM.

TriMet and Public Transport

TriMet is operating a standard weekday schedule today, but commuters should check for minor localized alerts on the MAX Blue, Green, and Orange lines. Notably, the agency is currently seeking public feedback on its proposed 2026 service efficiencies, which could affect the MAX Green Line and several bus routes later this year. The window for community input remains open until January 31, 2026. For those heading to the central business district, please note that many local government offices are closed for the holiday.

Commuter Safety and Visibility

Weather conditions today are expected to be sunny with a high of 46°F, but the Portland Bureau of Transportation (PBOT) reminds drivers that winter visibility remains a priority. Motorists are encouraged to use low-beam headlights during the early morning and late afternoon hours, even in clear weather, to remain visible to other drivers and transit operators in the low winter sun.
