Route description
It used to be divided highway with traffic signals, which even turned into a rural road near its south end, but due to the traffic congestion in parallel freeway PR-18, and also in PR-1 and PR-52, it had to be converted and is now 9.5 kilometers long.[http://www.dtop.gov.pr/carretera/det_content.asp?cn_id=126 Guía de Carreteras Principales, Expresos y Autopistas.] Departamento de Transportación y Obras Publicas de Puerto Rico. Accessed 3 May 2019. It has few exits; the first being to PR-169, a road to the rural area of Guaynabo and part of Aguas Buenas; PR-199 which connects it to PR-1 and PR-52; PR-177 which serves Bayamón and Cupey, and PR-17 ({{lang|es-pr|Avenida Jesús T. Piñero}}). It begins in the Muda sector of PR-1 and ends near San Patricio in Caparra, Guaynabo, at PR-2. It is tolled going north from PR-1, but not in the other direction.
