Puerto Rico Highway 577 (PR-577) is a short tertiary[2] mountainous state road that connects PR-143 (also known as Ruta Panorámica [Scenic Route] in this sector) to the Cerro Maravilla communications towers, in Barrio Anón, Ponce, Puerto Rico.

The road's northern terminus is at the Cerro Maravilla communications towers atop the Cerro Maravilla mountain, and its southern terminus is at its intersection with PR-143.

The road's primary purpose is to provide access to the television, radio and telephone communications towers located at the top of the Cerro Maravilla mountain.

The men, aged 18 and 23, had been lured to the place by an undercover police agent to attempt to destroy the communications towers in an effort to call attention to the incarceration of Puerto Rican political prisoners in the United States.

The killing of the two men was covered up by the Puerto Rico Police and several high-level Puerto Rico government officials, and were not investigated diligently by the FBI, for which a later FBI director apologized.
