History
The Oregon State Highway Department awarded the $568,181.00 ($ in dollars) construction contract to the Mercer, Fraser Company of Eureka, California, on January 16, 1930. Work began on the bridge at Gold Beach in April 1930. In order to avoid problems with concrete shrinkage that had plagued concrete arch bridges in the past, McCullough used the Freyssinet method of pre-tensioning the arches during construction using hydraulic jacks, using sixteen 250-ton jacks from Freyssinet's firm, enough to work with two arch panels at a time. McCullough's design was the first usage of this technique in the United States. The remote location of the building site presented a significant challenge, with reinforcing steel shipped southward from Port Orford, and built a concrete plant on the north bank of the river. Pilings for the piers were obtained locally. The bridge was planned to open in January 1932, but the ferry ''Rogue'' was damaged in December 1931 flooding and the bridge opened early, on December 24, 1931. It was dedicated on May 28, 1932 and named after Isaac Lee Patterson, the governor of Oregon from 1927 to 1929. The Mercer-Fraser Company presented the new bridge to the State on January 21, 1932, and the bridge was officially accepted as complete on January 27, 1932, at a final cost of $592,725.56.Description
The bridge is long and consists of seven deck arch spans and nine deck girder sections. The roadbed is wide, and the structure is wide overall. Piers 1 and 8, at the ends, rest on solid rock. The intermediate piers rest on driventimber pilings
Piling foundations support many historic structures such as canneries, wharves, and shore buildings. The old pilings present challenging problems during restoration as they age and are destroyed by organisms and decay. Replacing the foundation e ...
. Piers 2, 4, 5, and 7 rest on 180 vertical piles, while piers 3 and 6, required to resist lateral thrust, have 260 piers driven at an angle.
The detailing of the bridge incorporates Art Deco

crowned by sunbursts. The railings use a simplified, rectilinear Tuscan order with arches on short ribbed columns.
The bridge has required extensive preventive maintenance to mitigate deterioration due to the location's salt air. A $20 million rehabilitation ran from 2001 to 2004. A previous project in 1976 mitigated scouring problems at pier 2.
Construction of the bridge required the excavation of of earth and consumed of piling, of concrete, of reinforcing steel, and of structural steel.
