Puerto Rico Highway 823

Puerto Rico Highway 823 (PR-823) is a rural road located between the municipalities of Dorado and Toa Alta in Puerto Rico. With a length of 7.2 km, it begins at its intersection with PR-165 on the Contorno–Galateo line in Toa Alta, and ends at its junction with PR-677 and PR-679 in Espinosa barrio in Dorado.

Route description
Due to its rural characteristics, PR-823 has a single lane per direction in the entire length. In Dorado, it has a short length that extends from its intersection with PR-677 and PR-679 in Espinosa barrio to the Río Lajas, that serves as the municipal limit for Dorado and Toa Alta. In Toa Alta, PR-823 goes to the south through Río Lajas barrio from the Dorado municipal limit to PR-820, where it turns to the east. After PR-820 intersection, PR-823 meets with PR-142, with which it concurs for approximately 1 km in a southerly direction. Then, it continues to the east, passing through Quebrada Arenas barrio, where it intersects with PR-806 before crossing the Quebrada Arenas River. After the river, PR-823 serves as the boundary for Contorno and Galateo barrios until its eastern terminus at PR-165 junction.

History
Prior to its numerical designation, PR-823 was known as Carretera del Güinche and Carretera de Quebrada Arenas. 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 (Departamento de Transportación y Obras Públicas) that increased the insular highway network to connect existing routes with different locations around Puerto Rico.
