1953 Puerto Rico highway renumbering

Insular highways renumbered May 2025 1929-02 Año 6, Núm. 62 Page 20.jpg Highways in P.R. August 1928 Highways in P.R. August 1928 1953 Pre-Commonwealth: Insular Highway nn (Hwy nn) Post-Commonwealth: Puerto Rico Highway nn (PR-nn) PR In 1953, the Puerto Rico Department of Transportation and Public Works implemented a major renumbering of its insular highways. 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. 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. 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. History The first major roadways in Puerto Rico were built by the Government of Spain. By 1898, the year when Puerto Rico was ceded by Spain to the United States, 275 km us of roadways had been built. Additionally, 615 km mi were built between 1898 and 1908, 300 km mi more were added from 1908 to 1918, and 483 km mi were added from 1918 to 1927. By March 1928, there were 12 districts and some highway routes, particularly routes number 1, 2 and 3, crossed multiple districts. Some of the highways within the 12 districts included:Conservación District Road Numbers Notes 1 1, 3 2 1, 2, 3, 16 3 2, 13, 27 4 3, 4, Salinas-Cayey 5 2, 6, 13, 33, 34 6 6, 15, 17 7 1, 9, 10, 15 8 3, 5, 7, 28 9 2, 9, 10, 24 10 2, 8, 11, Guajataca 11 2, 11, 20 12 8, 13 List of highways July 2019 Old NumberSouthern or western terminusNorthern or eastern terminusLength, km (mi)New Number/sNotesRoute 1Barrio Playa in PonceLa Fortaleza in San Juan136.7 km mi valuesPR-123, PR-14, PR-1, PR-25Carretera Central.
