As of 1995, it was the oldest bridge truss in Puerto Rico, employing a double Warren pony truss design and unique open web transverse joists.

It was originally installed in 1881 as one of three spans of the Reyes Católicos Bridge over the Plata River on the San Juan–Mayagüez road, using metal parts fabricated in Belgium.

After a hurricane destroyed one of the other spans of the Reyes Católicos Bridge in 1899, this surviving span was moved and re-installed on new abutments under the supervision of engineer Rafael Nones in 1908, as part of the Comerío–Barranquitas road.

[2] The bridge was added to the U.S. National Register of Historic Places in 1995 and to the Puerto Rico Register of Historic Sites and Zones in 2000.
