This bridge is the oldest engineered structure in Washington County. The exact date is not known, but the National Road was through Washington County by 1818 and it is assumed that this bridge dates to that general time.

When you are travelling at stagecoach speeds, it is not a big deal to put curves in the road so that the bridge is perpendicular to the flow of the water.
