Puerto Rico Highway 53 (unsigned Interstate PR3) is a main tollway that is parallel to Puerto Rico Highway 3, which goes from Fajardo to Salinas. Some segments are still in planning, but when finished it will have about 59 miles (95 km) of length. Two tunnels, about 1 km (0.6 mi) long each, in the towns of Yabucoa and Maunabo were completed in October 2008 (2008-10). It will connect the cities of Fajardo, Ceiba, Naguabo, Humacao, Yabucoa, Maunabo, Patillas, Arroyo, Guayama and Salinas, thus bordering the entire eastern and southeastern coasts of Puerto Rico.
