Road Transportation
Puerto Rico has an extensive system of roads and highways featuring tolled freeways (autopistas). Some are designated as Interstate Highways; although these routes do not connect to the contiguous United States, and are unsigned as such, they still receive funding in a similar fashion to the other Interstates on the U.S. mainland. In total, there are more than 8,950 miles (14,400 km, 1999 est.) of paved road. Some of the major highways are:
PR-1 - Original main road between San Juan and Ponce before the completion of PR-52. It is now mostly used by people living nearby and as a scenic route.
PR-2 - Main freeway/highway/urban primary highway between/through Ponce, Mayagüez, Aguadilla, and Arecibo. Original main highway between Arecibo and San Juan before completion of PR-22 (currently undergoing a conversion to a freeway between Ponce and Mayagüez). This is the longest road in Puerto Rico.
PR-3 - (65th Infantry Avenue) Original main highway/urban primary highway between/through Salinas, Guayama, Humacao, Fajardo and San Juan (before completion of PR-52, PR-53, PR-66, and PR-26).
PR-22 - Main freeway between San Juan and Hatillo (plans are under way to extend the freeway to Aguadilla).
PR-52 (Las Américas Expressway and/or Luis A. Ferré Expressway) - Main freeway between San Juan and Ponce.
PR-10 - Main highway between Ponce, Adjuntas, Utuado and Arecibo (currently under construction: sections from Ponce to Adjuntas and Utuado to Arecibo are complete and open; while section between Adjuntas and Utuado under construction, with detour through PR-123).
PR-53 - Main freeway between Salinas, Guayama, Yabucoa, Humacao and Fajardo (currently under construction: section between Salinas and Guayama and Humacao to Fajardo are complete and open; while section between Guayama, Yabucoa and Humacao are currently under construction).
PR-66 - Main freeway between Canóvanas, Carolina, and San Juan (the freeway is being extended to reach the municipality of Río Grande, with its completion expected towards mid-late 2012).

Famous quotes containing the word road:
“Through the hollow globe, a ring
of frayed rusty scrapiron,
is it the sea that shines?
Is it a road at the world’s edge?”
