This bridge has a construction date of 1946-1949. However, because of the widespread use of lattice and v-lacing on the members of the bridge which are almost exclusively composed of built-up beams, the bridge looks more like it dates to the 1920s or 1930s. The bridge has two areas of historic and technological significance, relating to its truss spans. The main through truss span is historically significant for its large 463 foot span. Its truss configuration is also unusual, as it is a polygonal Warren truss bridge, but is subdivided in the manner that a Pennsylvania truss would be. The main span is flanked by deck truss spans which are also historically significant as uncommon examples of continuous deck truss spans. Located at each end of the main span, the spans are configured as three span continuous trusses with a variable depth bottom chord. It is particularly unusual to see continuous deck truss spans of this design functioning as approach spans. The bridge is completed with a series of steel stringer approach spans at the ends of the bridge.
This bridge was once part of US-66 and a major travel corridor over the Mississippi River. However, today, the primary use of this bridge is to access the main Chain of Rocks Bridge which was part of this same travel corridor but is today preserved for non-motorized use only. This canal bridge in contrast remains open to vehicular traffic, but it only serves one lane traffic, which is controlled by stoplights at the ends of the bridge. The remainder of the bridge roadway is devoted for non-motorized use.
