At the dawn of the new century, motor vehicles rapidly replaced wagons and stagecoaches as the primary conveyance on the bridge. The bridge continued to be used until 1958 and was donated to the National Park Service in 1961.

Spanning 400 feet, this bridge is the best-preserved King patent tubular bowstring bridge sill in existence.
