The first suspension bridge west of the Mississippi River was erected here in 1888. This concrete arch bridge was built in 1922 to replace it. The suspension cables from the original bridge were used to support the current bridge during construction.

The bridge was designed by Conde B. McCullough, and the bridge's Art Deco details are typical of McCullough's designs.

The bridge features a 360-foot half-through arch main span, and is one of only four of this type of bridge in Oregon.

Though the bridge structure appears to be built entirely of concrete, the arch is actually steel and is covered with a protective layer of sprayed-on concrete called gunite.
