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 and the Skyway, the road runs westwards for 10.2km to the junction with Diego Cera Avenue and Aguinaldo Highway. And 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.
