Winship Cancer Institute Pedestrian Bridge Jigsaw Puzzle Winship Cancer Institute Pedestrian Bridge What can you do with a streamlined single-story truss? Support a two-level IDEAS² Award-winning pedestrian bridge, of course--one that’s particularly sustainable because it uses as little material as possible! The truss lies at each side of the bridge’s top level, while the lower level is hung from hollow structural section (HSS) hangers at the truss panel points. In addition to making the bridge as efficient as possible, this arrangement allows for maximum transparency and light in the bridge’s lower level, which connects public spaces in the two hospital buildings.
