Oregon’s Crooked River Bridge Makes U.S. Construction History

Spanning the sheer walls of a 500-foot-high, 410-foot-wide river canyon with a concrete arch bridge posed unique construction challenges when first attempted in 2000-2001 by Kiewit Pacific Co. Schwager Davis, Inc. played a vital role in the project by consulting for the final construction scheme and designing and supplying the specially-designed traveling formwork and temporary stay cables and tower system that supported the cantilevered arch segments during construction.

The successful project garnered engineer Guido Schwager a nomination for ENR’s Top Newsmaker of 2000, and has also led to additional U.S. segmental arch bridge contracts, including the Hoover Dam Bypass Bridge currently underway in Nevada.
