I believe the bridge has been at this location since it was built. The piers have been upgraged and new approach piers added/upgraded, probably most recently at the time of the creation of the McClellan-Kerr Navigation System on the AR River- in the mid to late 1960s. The Bridge sits near the mouth of Lee Creek where it empties into the Arkansas River.
