NABSQNO 12S-610213-3861805. Agate Bridge is an example of the petrified log subclass of waterfall natural bridges. It is located in Petrified Forest National Monument, in Apache County, Arizona. Petrified Forest National Monument was established in 1906, in large measure to protect this natural arch. Concern about the arch's fragility led Monument staff to install pillars for support in 1911. The cement beam currently in place was installed in 1917. The black and white photo above was taken in 1895, and shows what the arch looked like prior to supports.
Vreeland listed Agate Bridge as number 11-22 in his catalog. It has a span of 25 feet.
