Alsea Bay Bridge
From Wikipedia, the free encyclopedia
The Alsea Bay Bridge is a concrete arch bridge that spans the Alsea Bay near Waldport, Oregon.
The original bridge was designed by Conde McCullough and opened in 1936. The hostile environment caused significant corrosion to the steel reinforcements. In 1972 the Oregon Department of Transportation began projects aimed at extending the life of the bridge. By the mid 1980s it was decided to replace the bridge rather than continuing costly rehabilitation efforts.
Construction of the new bridge began in 1988 and it was opened in the fall of 1991 at a cost of $42.4 million. The bridge is 2,910 ft in total length, with a 450 ft main span that provides 70 ft. of vertical clearance. The bridge has a latex concrete deck and the piers are significantly thicker than normal in an attempt to thwart corrosion. Its life expectancy is 75 to 100 years.
