Alsea Bay Bridge
The Alsea Bay Bridge is a concrete arch bridge that spans the Alsea Bay on U.S. Route 101 (US 101) near Waldport, Oregon.
History.
There have been two bridges on this site.
The first bridge was designed by Conde McCullough and opened in 1936. It was a long, reinforced-concrete combination deck and through arch bridge built in 1936.
The hostile environment caused significant corrosion to the steel reinforcements. In 1972 the Oregon Department of Transportation began projects aimed
an attempt to thwart corrosion. Its life expectancy is 75 to 100 years.
