One of the oldest bridges in the state of Kentucky, it can be found outside of military base of Fort Knox, along what remains of the old Louisville to Nashville Turnpike. As the name implies, the turnpike ran between Louisville, Kentucky and Nashville, Tennessee. There were two segments, known today as Highway 31 West and 31 East. The turnpike was used by both Union and Confederate troops during the Civil War, and the bridge dates back to before that time period. It was also traveled by President Andrew Jackson on several occasions. The western turnpike passed through Elizabethtown, Bowling Green, Glasgow Junction, and Franklin. And the eastern turnpike ran through Bardstown, Buffalo, Glasgow, and Scottsville
