Drift Creek Falls Suspension Bridge is located in the Coast Range of Oregon, about 10 miles east of Lincoln City and Highway 101.  Hugely popular, an easy 1.5 mile hike brings the visitor to the bridge, which vaults the Canyon more than 100 feet above Drift Creek.  Crossing Drift Creek Bridge is an other worldly experience as it carries the visitor through the forest canopy, offering a birds-eye view of the 80' tall falls cascading below. Drift Creek Bridge is dedicated to the late Scott Paul, a trailbuilder with the U.S. Forest Service, Mt. Baker-Snoqualmie National Forest, WA, whose vision and commitment to trails was the inspiration behind this incredible project.

Sahale became involved in the Drift Creek project after the design had been completed and the Forest Service had fabricated many of the bridge materials.  Work on the project had stopped during excavation of the abutments and anchors when the Forest Service Construction Foreman, Scott Paul, lost his life on the project in a tragic rigging accident. Sahale owner Carroll Vogel, long an associate of Scott's and a fellow trail builder, resolved to assist the Forest Service with completion of the project as a tribute to his lost friend and the community of trailbuilders in the Northwest who had lost one of their own.

Drift Creek Bridge is unusual for light pedestrian suspension bridges in that it incorporates a quasi-stiffening truss in the deck.  The bridge is anchored in rock on one side of the gorge and concrete deadmen are used on the other.  Numerous design changes were made by Sahale during the process of construction, including changes to the anchor systems, tower configuration, truss assembly, wind cable connections, and railing system.  Materials, including concrete, were mobilized to the site via helicopter, and the mainspan was erected from a skyline, more than 100 feet above the canyon floor.  The photos on this page show a view of the bridge and falls from below, and a view of the finished bridge with Bridge Specialist Keith Monohan at the tower top.
