Bridge No. 122, spanning the Santiago River near Naguabo, Puerto Rico, is significant as "one of the earliest and most elegant examples of concrete beam bridges in Puerto Rico". Built in 1918, it was "futuristic" for its time and has noteworthy architectural detail relative to others.{{rp|17,36}} It was designed by Rafael Nones and built by Felix Benitez-Rexach, both engineers, both regarded as masters in their work.{{rp|17}} Its construction was financed by Puerto Rico's second public bond issue for public works, in 1916, which raised $2 million.{{cite web|url={{NRHP url|id=64500544}} |title=Historic Bridges of Puerto Rico, c. 1840 - 1950 |publisher=National Park Service|accessdate=2016-05-13|author=Luis F.
