The Barbara Walker Crossing Footbridge, along the Wildwood Trail in Portland, Oregon, is up for the International CODA Award for commissioned art around the world. Click to watch the YouTube Video featuring the bridge. 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.

Engineering News Record: California awarded the Happy Hallow Pedestrian Bridge in San Jose, CA. an Award of Merit in the small projects category. Completed in March 2012, the bridge is the first of its kind in Northern California and consists of twin 270-ft identical spans. These were constructed using only two rolled sections for the arch ribs and for the tie girders and cross bracing. Albina Co., Inc. rolled 140,000# of W14 x 109# A709 50W the Easy Way to a 225 ft. radius and 90,000# of WT9 x 38# A709 50W split from W18 x 76# and then bent to various radii. A single cable size (3/4 in. dia) was used for both spans.
