Alabang–Zapote Road


Alabang–Zapote Road is a four-lane national road which travels east–west through the southern limits of Metro Manila, Philippines. It runs parallel to Dr. Santos Avenue in the north and is named for the two barangays that it links: Alabang in Muntinlupa and Zapote in Las Piñas.
From its eastern terminus at an interchange with South Luzon Expressway, Manila South Road, and Montillano Street, the road runs westwards for to the junction with Diego Cera Avenue and Aguinaldo Highway. Since 1997, it also extends further west for several hundred meters connecting Las Piñas to its present terminus at Coastal Road in Bacoor, Cavite.
The road carries more than 70,000 vehicles per day as of 2016, and suffers from traffic jams. The Metropolitan Manila Development Authority listed Alabang-Zapote Road as a major traffic bottleneck point or choke point, and the Unified Vehicular Volume Reduction Program, or "color coding" scheme, is modified for the road to no longer include window hours.
The entire route is designated as National Route 411 of the Philippine highway network.

History

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.

Route description
