The system of highways in Puerto Rico is made up of about 14,400 kilometers (8,900 mi) of roads.[1] It is managed by Puerto Rico's Department of Transportation and Public Works.[2]
The roads in Puerto Rico are divided into four types:[1]
- Primary roads
- Urban primary roads
- Secondary (or inter-municipal) roads
- Tertiary (or local) roads
A highway may contain several types of roads, but the highway will continue to have the same route number. Primary roads have numbers 1 to 99. Secondary roads are numbered 100 to 299. Municipal (tertiary) roads are numbered 300 to 9999.[3]
