Coos Bay (McCullough Memorial) Bridge Rehabilitation
The 1617 meter long Coos Bay (McCullough Memorial) Bridge was completed in 1936 as part of a Public Works Administration project that constructed five major river and bay crossings on the Oregon Coast Highway. The five bridges were designed under the direction of Oregon’s renowned bridge designer Conde B. McCullough and each bridge showcases McCullough’s skill in weaving aesthetic values into functional, economical structures that “fit” their unique sites. The McCullough Bridge is an unusually pleasant example of a cantilever truss that harmonizes with the arches of its approach spans. Since 2007, the Oregon Department of Transportation (ODOT) has been engaged in rehabilitation work on the Coos Bay (McCullough) Bridge. This work has included painting of structural steel members, impressed current cathodic protection of the north and south approaches, a polyester deck overlay, drainage improvements, seismic improvements, and installation of a replica historic “stealth” rail. This paper will use the Coos Bay Bridge projects as a case study to showcase the state of practice for bridge preservation in ODOT. In recent years, this practice has broadened in response to economic pressures and reductions in preservation costs, which are driving the application of bridge preservation techniques beyond historic bridges into “workhorse” bridges.
