Puerto Rico Highway 723 (PR-723) is a rural road that goes from the municipality of Aibonito to southern Barranquitas via northeastern Coamo, Puerto Rico. With a length of 9.6km (06miles), it begins at its intersection with PR-14 on the Pasto–Asomante line, passing through Pulguillas barrio until its end at its junction with PR-143 on the Coamo–Barranquitas municipal line.
This highway consists of two lanes in all of the entire length, one per direction, due to its rural characteristics. It is also part of the Ruta Panorámica, offering scenic views of southern Puerto Rico and the Cordillera Central. Near this highway, the Battle of Asomante took place, where Spanish and American troops met forces as part of the Spanish–American War of 1898.
The following barrios are located along Puerto Rico Highway 723:
Prior to its numerical designation, PR-723 was only known as Spanish; Castilian: Carretera de Pulguillas. The current numerical designation corresponds to the 1953 Puerto Rico highway renumbering, a process implemented by the Puerto Rico Department of Transportation and Public Works (es|Departamento de Transportación y Obras Públicas) that increased the insular highway network to connect existing routes with different locations around Puerto Rico.
