The General Norzagaray Bridge is a brick and masonry barrel vault bridge built in 1855 in San Juan, Puerto Rico. Also known as Puente de los Frailes, it brings what is now Puerto Rico Highway 873 across Frailes Creek, a tributary to the Guaynabo River. It has eight 9.8-metre (32 ft) barrel vault spans. Its total length is 120.7 metres (396 ft) and its roadway width is 7.00 metres (22.97 ft).[2] It was listed on the National Register of Historic Places (NRHP) in 1995.[1]
In 1855, it was important for carrying the Carretara Central across Quebrada Frailes.[2]
It is named for
It was designed by chief engineer
According to its NRHP registration, it "is one of the most impressive bridges from the Spanish Colonial period", serving as a "prime example of Spanish 19th century masonry arch technology".[2] It is the only such example in the United States.[2]
The superstructure of the bridge was modified in 1927 by removal of earth fill and addition of steel girders installed on the arch piers to support a concrete deck. This does not interfere significantly with the historic integrity of the bridge.[2]
It spans between what are now the barrios of Caimito and Tortugo in San Juan.
