In 1953, the Puerto Rico Department of Transportation and Public Works implemented a major renumbering of its insular highways.[1] Before 1953, highway routes were numbered in the 1 to just over 100 range and were distributed randomly throughout the island, resulting in several routes with long road lengths.[2] The numbering system adopted in 1953, which is in use today, increased the range of route numbers from the just-over-100 to 999, resulting in a decrease in the length of many routes.[3] This new numbering system follows a grid pattern for highways numbered between 100 and 999, with the lower numbered roads found to the west and systematically increasing towards 999 as the traveler moves easterly. Although PR-1, PR-2 and PR-3 routes had notable changes in some of their segments, these three are the only highways that kept their route numbers intact due to their interregional prominence.[4]
