History

Earlier spans

The first span recorded was built by 1901. That bridge was destroyed during a flood along the Yakima River in late 1917. This bridge was recorded on the Pasco quadrangle produced by the

in 1914. The letters "US" were inscribed in one of the approach spans of the bridge as a way marker for travelers through the region. Major flooding happened along the Yakima River near Benton City in 1894, 1917, 1922, 1933, and 1948. A new bridge was built after the original span collapsed in the flood. By 1954 the second bridge was considered no longer sufficient for the traveling public with a roadway less than wide. The second bridge was torn down in 1964, seven years after the opening of the current bridge.

Current span

The first proposals for the current bridge were submitted in November 1955, with a cost estimate of $140 thousand (equivalent to $ in ). The bridge was designed so that there was a clearance of higher than the 1933 Yakima River flood level. The new bridge was to be built downstream from the previous bridge, but was built upstream instead. The second bridge had been in place for 40 years and was seeing an
