Alabang–Zapote Road follows an old Spanish coastal trail that linked the Province of Manila to La Laguna and other southern provinces. It was called Calle Real or Camino Real which spanned from Ermita to Muntinlupa. At present, only the Las Piñas-to-Muntinlupa section is called Calle Real or Real Street as an alternative name for the road. The rest of the route had been renamed to Del Pilar Street in the City of Manila, Harrison Avenue in Pasay, Elpidio Quirino Avenue in Parañaque, and Diego Cera Avenue in Las Piñas.
