Holbrook in Navajo County, Arizona — The American Mountains (Southwest)
Enthusiastic visitors fascinated by Agate Bridge worked to preserve it through the establishment of Petrified Forest National Monument in 1906. Conservationists felt this ages old natural bridge needed architectural support and in 1911 erected masonry pillars beneath the log. In 1917 the present concrete span replaced the masonry work.
Current National Park Service philosophy allows the natural forces the create unusual feature to be left in its natural state. Eventually the natural forces that created Agate Bridge will cause it to fall with or without its supports. For your safety, and to help preserve the petrified log, please stay off the bridge.
