The highway system in Puerto Rico is composed of approximately 14,400 kilometers (8,900 mi)[1] of roads in Puerto Rico, maintained by the Puerto Rico Department of Transportation and Public Works (Spanish: Departmento de Transportación y Obras Públicas) or DTOP. The highway system in Puerto Rico is divided into four networks: primary, urban primary, secondary or inter-municipal, and tertiary or local (Spanish: red primaria, red primaria urbana, red secundaria o intermunicipal, and red terciaria o local).[1] Highways may change between networks and retain their same numbers.
