PR-18 is a freeway in Puerto Rico, which is also known as Expreso Las Américas. It runs from its north end in at its intersection with PR-22 (known as Expreso de Diego) in San Juan to its south end in Río Piedras where it intersects with PR-1. At this point PR-18 becomes PR-52, known as Autopista Luis A. Ferré.
PR-18 connects PR-52 to PR-22 and intersects with PR-17 (Ave. Piñero), PR-23 (Ave. Roosevelt), which grants access to Plaza Las Américas, and Ave. Domenech. It is mostly a 4-lane road in each direction. The combined route of PR-18 and PR-52 is coterminous with the unsigned Interstate Highway PRI-1.
