There have been two bridges on this site.
The first bridge was designed by Conde McCullough and opened in 1936. It was a 3011ft 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 at extending the life of the bridge. By the mid-1980s it was decided to replace the bridge rather than continuing costly rehabilitation efforts. The first bridge was demolished in 1991. Construction of the second bridge, designed by HNTB, began in 1988, and it was opened in the fall of 1991 at a cost of $42.4 million. The bridge is 2910ft in total length, with a 450ft main span that provides 70ft. 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.
