In an email from PBOT:
(March 27, 2026) The Portland Bureau of Transportation advises the traveling public that a landslide that was reported at about 8 a.m. today has led to the closure of NW Cornell Road, east of the Bird Alliance of Oregon.
NW Cornell Road is closed to all travelers, all directions in between the two tunnels where the landslide occurred. No vehicle or biking or walking access is allowed through the corridor.
Downed trees and power lines make the area hazardous and could cause a prolonged closure.
As of Friday morning, there is no estimated time for reopening this section of NW Cornell. Travelers are advised to expect no through traffic to be allowed on NW Cornell Road, between NW Thompson and NW Westover. Local access to area homes and businesses is allowed.
Access to the Bird Alliance facility at 5151 NW Cornell Road, is only allowed from the west. Expect to access the area via NW Skyline and NW Thompson Road. Go slow. Expect travel delays.
