In 1855, it was important for carrying the Carretara Central across Quebrada Frailes.[2]

Norzagaray Bridge in 1906.

It is named for Fernándo de Norzagaray y Escudero, governor of Puerto Rico from 1852 to 1855.[2]

It was designed by chief engineer Manuel Sanchez-Nunez y Layne and built by engineer Gustavo Steinacher (who also designed and built the first suspension bridge in the Caribbean, over the Caguitas River just north of Caguas, Puerto Rico[3]) and cost 45,346 pesos.[2]

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.
