Puerto Rico Highway 156 (PR-156) is a long east–west highway which connects Caguas to Orocovis, passing through Aguas Buenas, ComerÃÂo and Barranquitas. This route extends from its junction with PR-1 in downtown Caguas to PR-5155 in downtown Orocovis.
It is the main artery to Aguas Buenas from Caguas since the highway from Puerto Rico Highway 52 to the main downtown has at least two lanes and a shoulder per direction. From Aguas Buenas to Orocovis it is a rural, yet safe road which enters all the business districts and plazas of Aguas Buenas, ComerÃÂo, Barranquitas and Orocovis. It is one of two long east–west highways through the center of the island (the other being Puerto Rico Highway 111) but it never approaches a coast. Puerto Rico Highway 111 approaches Aguadilla's shore near PR-2 but PR-156, ending in Caguas, is nearly 35 kilometers away from the east coast.
Currently, Puerto Rico Highway 156 has two branches along its route. One of them is located in Orocovis and the other is between Aguas Buenas and Caguas.
Puerto Rico Highway 5156 (PR-5156) is an eastâÂÂwest avenue located in downtown Orocovis. This highways extends from PR-156 to PR-155, crossing the Orocovis River.
Puerto Rico Highway 7156 (PR-7156) is a rural, eastâÂÂwest road between the municipalities of Aguas Buenas and Caguas. This route is an old portion of PR-156 that connects the new alignment with PR-777 between Bairoa and Cagüitas barrios of Aguas Buenas. It extends from PR-156 west in Bairoa, Aguas Buenas, to PR-156 east in Cañabón, Caguas.
