This bridge is one of several surviving stone arch bridges dating to the first half of the 1800s that were built to carry one of the most important transportation routes in American history, the National Road, also called the Cumberland Road. 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.
A portion of the bridge's western approach was removed when US-40 (the modern equivalent of the National Road) was built next to the bridge, but most of the structure remains and is in good condition. A roadside park has been created around the bridge and a brief informative plaque is posted as the site relating the significance of the bridge and road.
