The Metro Manila Skyway is a fully grade separated elevated highway and motorway serving as the main expressway in the southern parts of Metro Manila, crossing over much of the existing South Luzon Expressway. It is located within the Metro Manila portion of the SLEX (South Luzon Expressway) from Nicolas Buendia Avenue(C-3 Road) to the Alabang-Zapote Road (AH-26) and crosses through the highly urbanized areas of Makati City, Pasay City, Parañaque City, and Muntinlupa City, relieving the South Luzon Expressway from heavy traffic.
The Skyway is the first fully grade-separated highway in the Philippines. It is still under improvement and maintenance though, for there are still several missing segments.
