Puerto Rico Highway 156

Puerto Rico Highway 156 (PR-156) is a long east–west highway which connects Caguas to Orocovis, passing through Aguas Buenas, Comerío and Barranquitas. This route extends from its junction with PR-1 in downtown Caguas to PR-5155 in downtown Orocovis.

Route description
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, Comerío, 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.
