Puerto Rico Highway 506

Puerto Rico Highway 506 (PR-506) is a two-lane tertiary highway in the municipality of Ponce in Puerto Rico. The road runs north to south, joining PR-14, where PR-506 starts, to PR-52 interchange, where it ends. The road is located entirely within Barrio Coto Laurel and its length is 2.0 km.

Route description
In its short 2.0 km length, PR-506 is home to Hospital San Cristóbal, Bolera Caribe, National University College, a pharmacy, a branch of the United States Post Office, a bank, and many restaurants, among other businesses and few neighborhoods located in Barrio Coto Laurel. The southern end of PR-506 also provides access to Industrias Vassallo and Cristalia Premium Water industries.

History
Until 2012 the road ran south to north starting at the easternmost edge of Mercedita International Airport at PR-1 and Camino Buyones, heading north and intersecting with PR-52 and continuing north to intersect with PR-14 where it ended. In that year, however, the Government of Puerto Rico abandoned maintenance of the stretch of the road from its PR-1 intersection to its intersection with PR-52, and the road was signed only from PR-52 to PR-14. At that time, the road was longer than its current 2.0 km.
