Description 

Puente San Antonio was constructed in 1924-25 to carry a new highway serving the dock area of the San Juan islet. It was erected parallel to existing highway, railroad and trolley bridges spanning the San Antonio Channel. Located within one of the most attractive urban areas of the Caribbean, this bridge lies today next to one of Puerto Rico's few remaining railroad bridges and near the modern occupant of the island's most historic bridge site. Puente San Antonio, designed and built respectively by Rafael Nones and Robert Prann, both renowned engineers, is listed in Puerto Rico's Inventory of Historic Bridges and mentioned in the Multiple Property Nomination of Puerto Rico's Bridges and its Associated Historic Context, Land Transportation in Puerto Rico, c. 1508-1950 as an exceptional beam bridge due to its monumental style. Although its standard beam structure is not considered significant in engineering terms, important items provide historic significance to the San Antonio Bridge: total length; number of spans; decorative elements; exemplification of the work of masters; the important route that it serves; and its surroundings.
