The Isaac Lee Patterson Bridge, also known as the Rogue River Bridge and the Isaac Lee Patterson Memorial Bridge, is a concrete arch bridge that spans the Rogue River in Curry County, Oregon. The bridge carries U.S. Route 101 across the river, near the point where the river empties into the Pacific Ocean, and connects the towns of Gold Beach and Wedderburn. A bridge with strong Art Deco influences, the Isaac Lee Patterson Bridge is a prominent example of the designs of the Oregon bridge designer and highway engineer Conde McCullough. It was designated a National Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1982. It is part of a series of notable bridges designed by McCullough for the Oregon Coast Highway in the 1930s. It was placed on the National Register of Historic Places in 2005.

History

Work began on the bridge at Gold Beach in 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 bridge is 1,898 feet (579 m) long and consists of seven 230-foot (70 m) deck arch spans and nine deck girder sections. The roadbed is 27 feet (8.2 m) wide, and the structure is 34 feet (10 m) wide overall. Piers 1 and 8, at the ends, rest on solid rock. The intermediate piers rest on driven timber pilings. 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 motifs, with prominent pylons at the ends with stepped Moderne elements and stylized Palladian windows 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.
