Spring Creek Pedestrian Bridge Winthrop, Washington

Spring Creek Pedestrian Bridge is a 385-foot clear-span cable-stay structure over the Methow River. Its design incorporated historical context from the town with elements that reflect 19th Century steel construction. The main steel truss and towers were constructed of weathering steel and the deck planks were precast concrete while tower foundations were designed to accommodate significant scour potential. Otak was responsible for structural design, stream hydraulics, and construction staking in partnering with Mowat Construction for this $2.5 million design-build project.
