Map

There are three officially designated Interstate Highways in Puerto Rico. As with Interstate Highways in Alaska and Hawaii, these routes do not connect to the United States Interstate Highway System, but still receive funding in a similar fashion to the Interstates in the contiguous US.

As with Interstate routes in Alaska (but not Hawaii), they are unsigned Interstate routes. The designated routes of the three routes — officially PRI-1, PRI-2 and PRI-3 — run along various combinations of Puerto Rico routes. They do not follow the rules of even and odd numbers determining direction.

Puerto Rico's interstate highways are not entirely built to Interstate standards. Various parts of PRI-2 and PRI-3 are not controlled-access; only PRI-1 is controlled-access in its entire length.

Puerto Rico's interstate routes are not to be confused with Puerto Rico Routes PR-1, PR-2, and PR-3. These three routes once made up Puerto Rico's entire interstate system, until they were supplanted by various expressways in certain segments. For example, PR-1 was once part of Interstate PRI-1, however, it has been supplanted by the PR-52 and PR-18 expressways, and thus the PRI-1 designation has since been reassigned to those expressways. Parts of PR-2 and PR-3 that are not paralleled by expressways remain part of PRI-2 and PRI-3, respectively, today.

Simple English

There are Interstate Highways in Puerto Rico that get money from the government. These Interstate Highways run along tollways and roads that are not grade separated, which means drivers must use a specially made group of ramps to get to the road. There are no signs for these Interstate Highways. They are signed as Puerto Rico routes.

The three Interstate Highways in Puerto Rico are:

  • Interstate PRI-1 goes from San Juan southwest to Ponce on the shortest route. It goes along Puerto Rico Highway 52 and Puerto Rico Highway 18. It is 71.08 miles (114.39 km) long.[1]
  • Interstate PRI-2 goes from San Juan to Ponce along the coast of western Puerto Rico. It goes along Puerto Rico Highway 22 and Puerto Rico Highway 2. It is 138.13 miles (222.30 km) long.[1]
  • Interstate PRI-3 goes from San Juan southeast to Ceiba. It goes along Puerto Rico Highway 53. It is 40.56 miles (65.27 km) long.[1]
