Puerto Rico Highway 31 (PR-31) is a main, rural highway connecting Juncos at Puerto Rico Highway 198 to Naguabo at Puerto Rico Highway 3.^[1]

Route description

PR-31 is an alternate route for people who are going from Caguas and other nearby towns to Naguabo, without having to pass through Humacao.^[3] It is located south of El Yunque and is constantly flooded, even with little rainfall.^[4] Several farms are close to this highway and it has two intersections with Puerto Rico Highway 53. Taking PR-30 and PR-53 to Naguabo can be faster depending on the traffic.
