context_page_description: The Roads in Puerto Rico are the national, forest and municipal roadways that make up the approximately 14,400 kilometers roads through the terrain of Puerto Rico. The highways serve the more than 3 million residents, and 3-4 million tourists who visit each year.
  Puerto Rico's territorial highway system is divided into four networks called primary, urban primary, secondary, and tertiary. As a road or highway changes from being part of one network type to another network type, it maintains its same number but is then marked with a corresponding shield. The National Highway System roads are maintained by the Puerto Rico Department of Transportation and Public Works.
  Puerto Rico's Interstate Highways, or the Puerto Rico Highway Program, which are not signed, are partially funded by the US federal government, as Puerto Rico's citizens pay federal taxes. At one time, Puerto Rico was treated as a state for the remittance of federal-aid highway funds, but with TEA-21, a legislative act, "Puerto Rico no longer receives a share of the apportioned Federal-aid highway funds.
context_section_description: The National Highway System of Puerto Rico (not to be confused with the National Highway System of the United States) consists of 1,151 km (715 mi) of highway and roadways of four types: primary, urban primary, secondary, and tertiary.
  All Puerto Rico expressways are signed either primary or urban primary. Puerto Rico's controlled-access highway may be an expressway, an arterial highway with full or partial control of access. Expressways with full control of access are called freeways. If the freeway charges a toll for its use, it is called an autopista. Most toll booths use the AutoExpreso system for collecting tolls.
  In 2009, primary routes were about 14% of the total Puerto Rico Highway system mileage, secondary were about 30%, and tertiary about 56%.
  As a road or highway goes from being part of one network to another, it maintains its same number but is then marked with its new network shield type. An example of this is when PR-1, connecting Ponce and San Juan, is signed as urban primary inside the Ponce city limits, then is signed as secondary in Ponce's rural barrio Capitanejo, and then is signed as an urban primary road, on its entry into the town of Santa Isabel. This means that regardless of the amount of digits a road number may have, any road could be signed as primary network, urban primary network, secondary network or tertiary network all dependent on the area it goes through.
