Puerto Rico Highway 503 (PR-503), also called Carretera Tibes (Road to Tibes),[4] is a tertiary[5] state[6] road that connects Barrio Consejo, in the southwestern part of the municipality of Utuado, to Barrio Tercero in the city of Ponce, and ending at Museo de la Historia de Ponce, one block east of the center of the city at Plaza Las Delicias.

Starting in 2008, the flow of this road through Barrio Tibes was interrupted by the construction of the Rio Portugués river dam.

PR-503 used to be a single stretch country road from Ponce to Utuado until the late 2000s when construction of the Portugués Dam changed that.

[1] In the mid 2010s a segment of this roadway was obliterated by the construction of the Portugués River reservoir, which now sits between the northern section of the road and the southern segment, disrupting the continuity of the road, but providing two approaches to the Dam and access to it from both the north and the south.

On 12 July 2011, Governor Luis Fortuño signed Law #130-2011 (House Bill 2885) naming this road as the David Medina-Feliciano Highway in honor of the costumbrista painter from Ponce.
