  • Roads in the Philippines

The highway is designated as a component of National Route 145 (N145) of the Philippine highway network and of Radial Road 3 (R-3) of Metro Manila's arterial road network.

The highway is named after Sergio Osmeña, the 4th President of the Philippines. In addition, its name is also alternatively applied on South Luzon Expressway's section from Magallanes Interchange to kilometer 28.387 in San Pedro, Laguna.[2]

Route descriptionEdit

Osmeña Highway (pictured in 2013) facing towards Manila, with the Buendia Flyover in the foreground, taken prior to the construction of Skyway Stage 3.

The Highway starts at a traffic light intersection with Quirino Avenue in Paco, Manila.[3] It traverses the districts of Malate and San Andres Bukid and crosses San Andres Street, Ocampo (Vito Cruz) Street, and Zobel Roxas Street. It then enters the city of Makati and climbs over to pass above Gil Puyat Avenue through the Buendia Flyover, with service roads to serve that avenue and several side streets.[4] The first stage of the elevated Skyway starts on the ramps past the flyover.[5][6] Osmeña Highway crosses Arnaiz Avenue and soon crosses over EDSA at the Magallanes Interchange, where the highway continues south as the South Luzon Expressway. Most of the highway parallels the PNR Metro South Commuter Line and runs under Skyway.[7][8][9]

The Paco–Muntinlupa segment of the Sucat–Paco–Araneta–Balintawak transmission line of National Grid Corporation of the Philippines (NGCP) uses the highway right of way from Quirino Avenue to Magallanes Interchange.

Road maintenanceEdit

The entire highway is classified as a national secondary road and is maintained by the Department of Public Works and Highways (DPWH) through the South Manila District Engineering Office and Metro Manila 2nd District Engineering Office in Manila and Makati, respectively.[7][8] The Metropolitan Manila Development Authority (MMDA) has jurisdiction also of both the tolled and non-tolled segments, and maintains motorcycle lanes up to Sales Interchange (Nichols).[10][11] It also handles the traffic management, alongside the local governments of Manila and Makati.[12]

Apparently, Skyway Operations and Maintenance Corporation (SOMCO), the operator of Skyway and a subsidiary of San Miguel Corporation, wanted Osmeña Highway to be under its control as the highway's section from Buendia northwards runs below Skyway Stage 3. SOMCO and SMC Tollways consider the highway's section from Buendia to Magallanes as part of Skyway At-Grade as it runs beneath Skyway Stage 1.[13][14] However, it was stated that SOMCO and Citra Metro Manila Tollways Corporation (now SMC Skyway Corporation), the concession holder of Skyway Stage 1, do not have jurisdiction over toll-free roads, including Osmeña Highway.[12]

South Superhighway is the older name of the highway and is more widely used alternatively up to date. It is also the former and alternative name of the tolled South Luzon Expressway.

The highway was renamed to President Sergio Osmeña Sr. Highway (often shortened as Osmeña Highway), after the Commonwealth President Sergio Osmeña, by virtue of Republic Act No. 6760 in 1989.[1] The name also refers alternatively to the segment of the tolled South Luzon Expressway from Magallanes Interchange to Kilometer 28.387 in San Pedro, Laguna. It was also applied further south to Calamba, Laguna until 1992, when this segment was renamed after Dr. José Rizal by virtue of Republic Act No. 7625.[2]

The highway was originally built apparently in the 1960s as part of the newer road connecting Manila and Southern Luzon.[15][16][17] It was built in parallel to the Philippine National Railway's Batangas extension line and over the old Hernandez Street in San Andres, Manila.[18] It was renamed in 1989 to President Sergio Osmeña Sr. Highway by virtue of Republic Act No. 6760.[1]


Osmeña Highway is accessed through jeepneys, taxis, and buses. Running parallel to the PNR Metro South Commuter Line, the highway is served by Philippine National Railway (PNR) stations namely: San Andres, Vito Cruz, Dela Rosa (replacing Buendia), Pasay Road, and EDSA (interchange to MRT Line 3 at Magallanes station).
