Inclement Weather

Hospitals and clinics

OHSU Hospital, Doernbecher Children's Hospital, and the Emergency Department are always open. Outpatient clinics make every effort to remain open as well, while still ensuring the safe arrival of our patients.

When the weather forecast is calling for ice or snow, call the OHSU Alert Line: 503-494-9021.  A recorded message will provide road conditions and information.

If you are a patient and are concerned about road conditions, or want to change your appointment, please call your doctor's office directly.

Marquam Hill road conditions

Sam Jackson Park Road above the water tower is a designated snow zone; traction devices are required when snow is on the ground, falling or imminent. An alternate Marquam Hill route—taking Terwilliger to Campus Drive—may be available without traction devices even when Sam Jackson Park Road requires them.

You can view live road cams to see conditions on Marquam Hill from six vantage points.

Public transportation

Public transportation may be the safest option during bad weather, but you’ll want to be prepared.


TriMet may decide to suspend service to Marquam Hill and instead divert buses to the base of the Tram. Follow TriMet’s service alerts call 503-231-3197 for altered routes.

Portland Streetcar also stops at the base of the Tram.


C-TRAN will cancel Line 190 Marquam Hill Express service during inclement weather, and instead run an alternative to/from downtown Portland. There, riders can then transfer to TriMet and then the Tram. For more information go to C-TRAN’s website or call 503-283-8054.

Portland Aerial Tram

If buses are diverted, Tram wait times could increase. Tram hours will be expanded as necessary.

Snow and ice per se won’t stop the Tram, but high winds can force its closure because they can make the trip unsteady and unpleasant for many. In high winds, road conditions permitting, shuttle buses will run instead.
