Eastern end of Highway 116 in Guanica where it meets Highway 2
Puerto Rico Highway 116 is a main highway in the southwest part of Puerto Rico, beginning in Guánica, Puerto Rico at Puerto Rico Highway 2 to Lajas, Puerto Rico at Puerto Rico Highway 101. It is the main route to Guánica and Lajas, and grants access to places such as the Dry Forest of Puerto Rico (Bosque Seco), common for its cacti and dry, desert-like climate, and also to beaches like Parguera in Lajas and Playa Santa in Guánica. It is divided, two lane-per-direction in the first 4 kilometers before turning one lane-per direction in the rest of its length. The width of its lanes allows for speed limits above the normal rural roads.
