The Portland Aerial Tram is a 3,300 linear foot aerial tram rising 500 feet over Interstate 5, the Lair Hill neighborhood, and Terwilliger Parkway and connecting OHSU and the Marquam Hill to the South Waterfront District. Construction of the Tram will be completed in winter 2006-07 and will serve as a catalyst for the South Waterfront redevelopment and the continued emergence of OHSU as a top-tier medical research institution. Designed by agps architecture and Doppelmayr-CTEC, the tram will provide approximately a 3 minute ride between the two areas, with views of Mt. Hood and Downtown Portland.

Planners project that in the first five years, the aerial tram will support about 1,500 round trips a day for activities in the OHSU Center for Health & Healing, the university's first building in the South Waterfront. Because the aerial tram is part of the public transportation system and open to the public, planners expect ridership to exceed this estimate. Twenty years from now when the South Waterfront is more mature in its development, about 5,500 OHSU-related round trips are expected each day.
