Largest Natural Travertine Bridge in the world
15.02.2017
Tonto Natural Bridge is a natural arch in Arizona, USA, that is believed to be the largest natural travertine bridge in the world.
Tonto Natural Bridge stands over a 400-foot-long (120 m) tunnel that measures 150 feet (46 m) at its widest point and reaches a height of 183 feet (56 m).
Very beautiful bridge and park, left early in the am for 2 hr drive North from Phoenix. It's in a very remote area that would be lovely in Summer, a little chilly now in Feb.
