Flying stairway.

Repairs to the cable on the aerial tram, at least that's what I presume they were doing. What an amazing set up. Stopped the car so I could get out and blip it. Probably best viewed in large so the workmen can be seen. I was getting giddy just taking the pix, I can't imagine walking up that thing. The aerial tram links the OHSU (Oregon Health & Science Hosptial) campuses at the South Waterfront and the top of Marquam Hill (locally known as Pill Hill).
