Description 

The original Theodore Roosevelt Dam was a massive masonry structure carrying AZ 188 on its top. It is the world's largest masonry dam, built from 1903-1911. When the dam was reconstructed to make it higher in 1989-1996, a separate bridge had to be built first to carry the roadway over the Salt River. At that time the closed-spandrel arch approach spans were demolished and the original roadway buried within the enlarged dam.
