Segment of NW Cornell Road to close until spring
A segment of Northwest Cornell Road will be closed to vehicular traffic starting Monday, Aug. 23, for two tunnel repairs, according to the Portland Bureau of Transportation.
The road will be closed between Northwest 30th and 53rd avenues and won't open again until spring 2022. Cyclists and pedestrians, however, will have access to the road. They will need to use the existing paved paths that go around the tunnels.
Eastbound traffic will be detoured to Northwest Skyline Boulevard, while westbound traffic will be detoured from Northwest 23rd Avenue to West Burnside Street, officials said.
Local residents and businesses located along the corridor, including the Audubon Society and Adams Community Garden, will still have access to the road.
The reason for these closures and extensive repairs is because of a large crack near the crown of the western tunnel that was found in a recent inspection, city officials said.
A 2019 assessment and subsequent engineering report recommended the tunnel lining should be strengthened to prevent any further structural failures.
"This project will provide the recommended tunnel lining strengthening and lining coating and considerably extend the useful life of the tunnels," the Portland Bureau of Transportation said in a news release.
The project will provide additional lining to strengthen the tunnels and add to their longevity, officials added.
