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 after the two barangays it links: Alabang, Muntinlupa and Zapote in Bacoor and Las Piñas.

From its eastern terminus at an interchange with South Luzon Expressway's Alabang Exit, East Service Road, Manila South Road, and Montillano Street, the road runs westwards for approximately 10.9 kilometers (6.8 mi) to the junction with Diego Cera Avenue. Since 1997, it has also extended 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 "number coding" scheme, is modified for the road to no longer include window hours.

The entire route is designated National Route 411 (N411) of the Philippine highway network.
