Positively Not Pedestrian

Abstract:

An elaborate pedestrian and bicycle bridge in Eugene incorporates a number of innovative engineering features to create an aesthetically pleasing structure to complement the surrounding area. A sheathed cable system that provides corrosion protection for the main cables was used for the first time in the U.S. A sculptured inverted tripod structure serves as both the main cable anchorage and as the support for a large saucer-shaped observation area and approach span. Additionally, the main cables pass through the center of the deck sections to provide unimpeded access to a midspan observation platform. The designers incorporated many cable-stay corrosion prevention methods into the suspension bridge, requiring FHWA approval.
