Puerto Rico Highway 810

Puerto Rico Highway 810 (PR-810) is a north–south road located entirely in the municipality of Naranjito in Puerto Rico. With a length of 3.7 km, it begins at its intersection with PR-164 on the downtown Naranjito–Achiote line, and ends at its junction with PR-152 in Cedro Abajo barrio.

Route description
Due to its rural characteristics, PR-810 consists of one lane per direction for its entire length. It begins at PR-164 junction near downtown Naranjito and continues to the south through southwestern Achiote barrio, near to the western bank of the Río Guadiana. After Achiote, the highway enters in eastern Cedro Abajo barrio, where meets with PR-814, a road that leads to Anones barrio. Then, PR-810 continues within Cedro Abajo until its southern terminus at PR-152 junction.

History
Before its current numerical designation, the entire length of PR-810 belonged to an original segment of PR-152 prior to its deviation along the eastern bank of the Guadiana River though Anones. Those numerical designations correspond to the 1953 Puerto Rico highway renumbering, a process implemented by the Puerto Rico Department of Transportation and Public Works (Departamento de Transportación y Obras Públicas) that increased the insular highway network to connect existing routes with different locations around Puerto Rico. PR-810 is also known as Carretera de Higuillales.
