Puerto Rico Highway 3 (PR-3) at nearly 101 miles long, is the second longest highway on Puerto Rico (after PR-2). It connects the San Juan neighborhood of Rio Piedras to downtown Salinas indirectly around the eastern coast of the island. Highway 3 ranges from a three lane urban avenue in San Juan to a one lane rural road past Fajardo.While other roads connect San Juan It runs the coastline of Puerto Rico east of San Juan, beginning in Rio Piedras near Santurce (where it is known as the Avenida 65 de Infantería) and goes to Fajardo where it goes south paralleling the coastline to Humacao and Maunabo. It goes up to a mountain-scenic route and goes west to Salinas, where it meets PR-1.
PR-3 begins at an intersection with PR-1 in San Juan as the three lane 65th Infantry Regiment Avenue. Heading east through San Juan, Highway 3 functions as an urban boulevard with both at-grade and grade-separated intersections becoming decidedly suburban in character past the PR-26/66 overpass near downtown Carolina. Recently, PR-66 was opened and it has controlled the high traffic on PR-3.
