Portland Aerial Tram, Urban aerial tram in Portland, United States

The Portland Aerial Tram runs between a lower station in the South Waterfront district and an upper station at OHSU Hospital on Marquam Hill. Its two white cabins, built by Gangloff AG of Bern, hang from a single 197-foot intermediate tower and travel 3,300 feet horizontally while rising 500 feet. Each cabin holds 78 passengers and one operator.

The installation came from a partnership between the city of Portland and the university, opening in December 2006 after years of planning. The investment aimed to improve access from the expanding riverfront district to the existing medical center.

The cars were built by Gangloff AG of Bern, Switzerland, and shaped and painted to resemble "bubbles floating through the sky". Their reflective surfaces refract light, reducing the visual impact on the neighbourhood below. The tram is one of only two commuter aerial tramways in the United States, the other being New York City's Roosevelt Island Tramway.

The tram runs Monday to Friday from 5:30 a.m. to 9:30 p.m. and Saturdays from 9:00 a.m. to 5:00 p.m.; it is closed Sundays and major holidays, except for afternoon summer Sunday service. The lower station sits beside a Portland Streetcar stop in South Waterfront, and the upper station links to OHSU Hospital's ninth floor by a skybridge. TriMet, C-Tran and Portland Streetcar monthly and annual passes are honored.

The cabins rise roughly 150 meters (about 500 feet) in elevation during the trip, so the view of the city and surrounding peaks changes continuously. On clear days, both Mount Hood and Mount St. Helens become visible through the windows.
