Because of its proximity to Lake Powell, Rainbow Bridge is today heavily visited during the warm months. During 1988 the monument received 238,307 recorded visitors.
A Bureau of Reclamation report dated 1985 stated that a ten-year study showed that the presence of Lake Powell had no effect on the stability of the bridge. The report continued, "Joint controlled rockfall was the predominant erosive process in forming the bridge. [This process is] actively continuing today and will eventually cause the destruction of the bridge."
