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 10.2 kilometers (6.3 mi) 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 (R-1) 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 (MMDA) listed Alabang–Zapote Road as a major traffic bottleneck point or choke point, and the Unified Vehicular Volume Reduction Program (UVVRP), or "color coding" scheme, is modified for the road to no longer include window hours.
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 (Spanish for "royal street") or Camino Real (Spanish for "royal way") 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 (from Manuyo Uno to Zapote).
The road begins at the junction of Manila South Road, Montillano Street, and South Luzon Expressway's Alabang Exit in Alabang, Muntinlupa, near Starmall Alabang. It then crosses into Filinvest City and Barangays Cupang and Ayala Alabang, where Alabang Town Center and the Madrigal Business Park are located, intersecting with Madrigal Avenue and Acacia Avenue. West of Daang Hari Road (Investment Drive), it then enters Las Piñas and Barangays Almanza Dos and Almanza Uno, where SM Southmall is located. From Marcos Alvarez Avenue to CAA Avenue-BF Resort Drive, the road traverses Barangays Talon Uno, Talon Dos, Talon Tres, and Talon Cuatro. It then traverses Barangays Pamplona Tres, Pamplona Dos, and Pamplona Uno as it goes past the Las Piñas City Hall, SM Center Las Piñas, and Starmall Las Piñas. A flyover and bridge was built in 1997 to connect Zapote, Las Piñas with Zapote, Bacoor (Longos) over the Zapote River where the road ends at an interchange with Coastal Road (CAVITEX). Electric power subtransmission lines by Meralco, placed on tall roadside posts, also shared by distribution lines, line almost the whole length of the road from Zapote in Las Piñas to Alabang in Muntinlupa and the proposed Las Piñas–Muntinlupa Expressway, which is worth ₱2.75 billion.
As of July 2016[update], the Las Piñas Traffic Management Office reported more than 70,000 vehicles travelling on Alabang–Zapote Road daily, that already reached above its allowable capacity. The road gained notoriety for its traffic jams, and it is listed by the Metro Manila Development Authority as a major traffic bottleneck area in south Metro Manila, along with other major roads leading to Ninoy Aquino International Airport, like Sucat Road, Andrews Avenue, and Domestic Road. The Unified Vehicular Volume Reduction Program (UVVRP), or the "coding" scheme, is modified for Alabang–Zapote Road to have no "window hours".
