Helix Pedestrian Bridge

A 400’ pedestrian bridge linking Elliott Bay Park and the Amgen Research and Development Center to the lower Kinnear Park and Queen Anne hill at W. Prospect Street in Seattle. The bridge is formed by a single clear span arch supported by a pair of canted arches, creating an abstract image of the double helix DNA form. The bridge is clad in stainless steel, mesh and tensioned fabric as it crosses the Burlington Northern railway.
