Slick Morning Roads and Milestone Highway Project Completions for Friday, Feb. 20

Morning Weather and Road Hazards

Commuters in the Portland metro area should exercise caution this morning, Friday, February 20, 2026. A Winter Weather Advisory remains in effect until 4:00 AM, leaving the potential for slick patches and slushy conditions on bridges, overpasses, and untreated neighborhood side streets. While the heaviest precipitation has moved through, morning temperatures near freezing mean that drivers should expect a slower-than-average start to the day. Maintenance crews have been monitoring high-elevation routes, but localized ice may still be a factor in the West Hills and higher elevations of East Portland.

Highway Construction and Arterial Updates

Several significant roadwork projects are reaching milestones today, though some restrictions continue to impact early-morning and late-night travelers:

• I-5 Northbound: The nightly width restriction between Milepost 301.59 and 301.96 is scheduled for completion today. Drivers should expect the 14-foot restriction to lift after the 5:00 AM window, easing passage for commercial vehicles.
• I-205 Corridors: Infrastructure work near Oregon City and West Linn continues. The I-205 northbound Exit 9 off-ramp to OR99E is scheduled to complete its current phase of nightly closures today. However, travelers should note that an additional nightly closure is scheduled for this evening starting at 10:00 PM and extending until 7:00 AM Saturday morning.
• Terwilliger Boulevard: On Interstate 5 southbound, expect short-term overnight lane and shoulder closures between Mileposts 297 and 300. Crews are finalizing the installation of RealTime Variable Advisory Speed signs designed to improve safety on the curves south of downtown.

Public Transit and TriMet Alerts

TriMet is advising riders to monitor real-time service alerts this morning due to the residual effects of the winter weather. While most MAX light rail and bus lines are running on standard Friday schedules, weather-related delays are possible on lines serving hilly terrain, such as Line 20 (Burnside/Stark) and routes in the West Hills. Additionally, TriMet continues to seek public feedback on proposed 2026 service adjustments and potential cuts to lines like the 76 and 97. Commuters are encouraged to use the official TriMet tracking tools for the latest on-street customer service information before heading to their stop.

New Traffic Response Technology

Beginning today, the Washington County Sheriff’s Office is launching a trial of its "Drone as First Responder" (DFR) program. This technology is designed to assist patrol deputies in gathering real-time data at crash sites and other major incidents. By providing aerial views of traffic hazards, the program aims to help emergency services clear road-blocking incidents more efficiently. While the drones will be remotely operated by licensed pilots, residents may notice increased drone activity in areas where traffic investigations are underway.
