What’s Cool In Steel?: December Issue of Modern Steel Features Barbara Walker Crossing Footbridge

What’s Cool In Steel? Modern Steel presents tons of fun projects showcasing the use of cool steel in the December Issue, including the Barbara Walker Pedestrian Bridge along Portland’s Wildwood Trail. The Barbara Walker Crossing Footbridge is a two time CODA Award Winner. The bridge, designed by local artist, Ed Carpenter, is 178’ long measured at the center of its curving deck. Its basic structure is a tri-chord truss of rusting and painted steel. Carpenter’s design evokes imagery of the sword ferns and vine maples lining the entire length of the Wildwood Trail. This project is a collaborative effort of the Portland Parks Foundation in partnership with Portland Parks & Recreation (PP&R), the Portland Bureau of Transportation (PBOT), and Metro. Albina Co., Inc. bent 3½” SCH80 A847 and 5″ SCH40 A847 all rolled to various radii, as well as 1″ SCH40 A53B, 1½” SCH40 A53B, 1½” SCH80 A53B all rolled to various radii. (Photo Credit: Ed Carpenter).
