This bridge has a complicated history. It was first built from 1946-1947 as a deck truss featuring two truss lines. There were two bridges, a west bridge, and an east bridge, separated by an island in the river. The steel on the bridge as originally built was not of good quality however, and February 1950 cracks started to form in the bridge (both the west and east bridge). In January 31, 1951 in very cold weather, the unusually brittle steel coupled with the cold temperature caused the west bridge to collapse. Four people died in the collapse. The bridge superstructures were then demolished and replaced with new deck truss spans of heavier design, including four truss lines instead of two for each span. The work was completed in 1953. Some of the original 1940s structure, including decorative pillars at the ends of the bridge, were retained. Thus, the bridge is a combination of 1947 and 1953 construction.
More recently, it appears the eastern bridge was demolished and replaced, as the eastern bridge is no longer a truss bridge and is instead a girder bridge. This may mean the western bridge is at risk for demolition and replacement as well. As such, the HistoricBridges.org page seen here covers only the western bridge. It is made up of six spans of 54.8 meters (180 feet) and two spans of 45.7 meters (150 feet).
