Fog Advisories and Key Corridor Restrictions Impact Friday Commute

Morning Weather and Visibility Alerts

Commuters in the Portland metro area should exercise extra caution this morning, Friday, February 6, 2026, as a freezing fog advisory remains in effect until 10:00 AM. Visibility is significantly reduced in the foothills and low-lying areas, making for hazardous driving conditions during the early peak hours. In addition to the fog, a regional air stagnation advisory is active until 10:00 PM tonight. While this does not directly block roads, the lack of wind movement can lead to deteriorating air quality, particularly for those using active transportation like cycling or walking.

Major Highway Impacts and Restrictions

Several major arteries are experiencing ongoing construction and restrictions that may slow your trip today:

• Interstate 5 (Rose Quarter & South Portland): Work continues on the RealTime Variable Advisory Speed sign project. Drivers should watch for intermittent daytime lane shifts between the Ross Island Bridge and Terwilliger Boulevard. For freight operators, please note that height and width restrictions are active near the I-405 interchange, with southbound height limited to 16' 2" and northbound width restricted to 14' 0".
• US-30 (NW St. Helens Road): Repaving and safety improvements are underway between NW Bridge Avenue and NW Kittridge Avenue. Expect periodic daytime lane closures and 20-minute delays. Pedestrians and cyclists should follow posted detours as sidewalk and bike lane access is limited in this zone.
• I-205 (Stafford Road): The "Bus on Shoulder" project between MP 3 and MP 13 continues. While daytime traffic impacts are minimal, shoulder closures are in place, and drivers are urged to stay alert for crews working near the travel lanes.

West Side and Local Road Closures

Significant disruptions are reported in Washington County and Hillsboro that may require alternative routing:

• SW River Road: A major long-term closure remains in effect between SW Davis Road and SW Rosedale Road for deep sanitary sewer installation. This closure is expected to last through April, so commuters should continue using established detours.
• SW Brookman Road: The intersection at Oberst Road is closed for utility work until February 16. Local traffic is being rerouted, and through-travelers are advised to avoid the area entirely.
• 185th Avenue: Development work near Alderwood Drive is causing sidewalk and lane closures. Expect delays throughout the day in this high-traffic corridor.

Public Transport Update

TriMet is currently operating on a standard weekday schedule; however, riders should remain aware of the ongoing public discussions regarding the $300 million budget shortfall. While service remains stable today, significant route adjustments and frequency reductions are slated to begin on March 1, 2026. For today's commute, the MAX Green, Blue, and Red lines are reporting normal service, but commuters are encouraged to check for real-time bus arrivals as morning fog may cause slight delays in suburban transit loops.
