Sucat-Alabang Skyway Connection and Ramp Extensions Project

Project Description: 

• Three (3) lanes will be added from SLEX Muntinlupa to Skyway Main Toll Plaza (Northbound). There will be a new access from Alabang viaduct to Skyway Alabang-Zapote elevated toll plaza. Two (2) lanes will be added from Skyway Main Toll Plaza to SLEX Muntinlupa (Southbound).
• The Project includes construction of the following:
1. Northbound ramp from SLEX Muntinlupa to the Skyway Main Toll Plaza
2. Northbound ramp from Alabang viaduct to the Skyway Alabang Toll Plaza
3. Southbound ramp from the Skyway Main Toll Plaza to SLEX Muntinlupa
4. The Skyway Alabang Toll Plaza will also be widened to add more toll lanes to accommodate more motorists both from Northbound and Southbound directions

Project Objectives: 

This project aims to:
• Aid in the decongestion of traffic at the existing Metro Manila Skyway by providing a direct access to and from the elevated Skyway to South Luzon Expressway through the Alabang Viaduct
• Reduce travel time by around 50%, as motorists will be diverted from the at-grade segment of the Skyway to the elevated link for motorists who intend to go directly to and from SLEX and vice versa.
