# Avenida Juan Ponce de León

Avenida Juan Ponce de León (Juan Ponce de León Avenue), also known as the Avenida de la Constitución (Constitution Avenue), and coextensive as Puerto Rico Highway 25 (PR-25) along its entire length, is one of the main thoroughfares in San Juan, the capital municipality of Puerto Rico. Named after Juan Ponce de León, the Spanish conquistador who led the European colonization of the archipelago in 1508 after its discovery by Christopher Columbus during his second voyage in 1493, it connects the historic quarter of Old San Juan in San Juan Islet with the residential and resort barrio of Santurce, the business center of Hato Rey, and the commercial and residential district of Río Piedras in the main island. It is one of the oldest roadways in Puerto Rico, as some sections are dated to at least 1519.

## Route description

It is a mostly three-lane, one-way road. It runs from Old San Juan to Río Piedras pueblo and, for most of its length, it is a three- or four-lane road traversing the Isleta de San Juan corridor. The section running through Río Piedras pueblo is the only section that is not a multi-lane roadway.
