WEST END BRIDGE
Pittsburgh, PAStatus: Competition Winner 2006
This design was chosen from among a world-class field of competition for its technical achievements. An unprecedented self-anchored design evolved from the desire to use the existing bridge and foundations as a framework from which to suspend the new spans. Anchored to the existing historic West End Bridge spanning the Ohio River in Pittsburgh, PA, this design respects the geometry and graceful form of the existing span while enhancing the structure with a dynamic, high-tech, suspended pedestrian deck. The project includes a new 778-foot long span pedestrian bridge, doubling the length of the longest existing ring-cable design. This concept reduces the load on the bridge tie as well as improving its safety. In addition, the new structure was laid in front of the bridge so that only a small arc would be visible in elevation from Point State Park. This allows the structure to line up without projecting too far from the existing bridge, enabling a much larger span.
