Project Gallery / Amgen Helix Pedestrian Bridge

One of Seattle's newest architectural attractions is not a new sports stadium or an art museum, but a unique pedestrian bridge.

The extraordinary 420-foot Amgen Helix Pedestrian Bridge spans eleven railroad tracks and connects the campus of one of the world’s largest biotechnical firms with a major transportation hub.

The three-dimensional helix design represents the vital DNA research conducted at Amgen’s facility and highlights Birdair’s engineering and construction capabilities beyond architectural fabric membrane design.

In 2004, the Amgen Helix Pedestrian Bridge received the “Outstanding Project” award under the Bridges and Transportation category given by the National Council of Structural Engineers Association.
