South Luzon Expressway

Pres. Sergio Osmeña Sr. Highway/South Superhighway

Pres. Sergio Osmeña Sr. Highway segment of SLEx in Magallanes, Makati just south of Magallanes Interchange.

The Pres. Sergio Osmeña Sr. Highway segment starts from an intersection at Quirino Avenue in Paco, Manila and goes straight up to Alabang in Muntinlupa. The part of Osmeña Highway which passes through Manila, Makati, Pasay and Taguig is a toll-free highway before reaching the Nichols Toll Plaza from which the tolled expressway begins. Heading southward, the expressway has exits in C-5 Road in Taguig, the Merville Subdivision and Bicutan in Parañaque, and Sucat, Alabang, and Filinvest in Muntinlupa. This segment was formerly known as South Superhighway before Republic Act 6760 was passed, naming it after former President Sergio Osmeña.^[1] Most of Osmeña Highway parallels the PNR Metro South Commuter Line.

Osmeña Highway starts at the traffic light with Quirino Avenue. It then crosses San Andres Street, Ocampo (Vito Cruz) Street, and Zobel Roxas Street. The highway climbs over to pass above Gil Puyat Avenue through the Buendia Flyover, with service roads to serve that avenue and several side streets. The Skyway starts on the ramps past Buendia Flyover. Osmeña Highway crosses over Arnaiz Avenue, and soon crosses over EDSA at the Magallanes Interchange. The concurrency with the Pan-Philippine Highway starts at that interchange. Past Magallanes Interchange, the highway features 5 lanes, with 1 lane designated as motorcycle lanes until it comes near Nichols Interchange, where the toll road starts. Osmeña Highway becomes a toll road past the Sales Interchange, with motorcycles below 400cc prohibited to use the tolled expressway.

The part of Osmeña Highway north of Magallanes Interchange is maintained by the Department of Public Works and Highways (DPWH) through the South Manila District Engineering Office, and the portion south is maintained by the Skyway Operations and Management Company. The Metropolitan Manila Development Authority (MMDA) has jurisdiction also of both segments, and maintains motorcycle lanes up to Nichols.

Skyway At-Grade (Nichols—Alabang)

South Luzon Expressway and Skyway near Villamor Airbase at the Pasay-Taguig boundary.

From Nichols, Past the Sales Interchange, Osmeña Highway becomes the tolled At-Grade Skyway System. The expressway includes two service roads until Alabang Exit. The PNR Metro South Commuter Line runs between the At-Grade and Elevated Skyway segments until it passes over C-5 Exit. The expressway and its service roads run through the Pasay-Taguig boundary until it reaches C-5 Exit. Past C-5 Exit, the elevated segment runs over the at-grade segment up to Alabang. The Skyway system slightly curves and passes over Bicutan, running as a straight route with the Elevated Skyway segment above until it reaches Alabang Exit and Alabang Viaduct. The expressways mostly runs through the Parañaque-Taguig boundary until it comes near Sucat, where it crosses Dr. Santos Avenue. The Skyway system enters Muntinlupa, passing over barangays Sucat, Buli, and Cupang, before approaching Alabang. The elevated Skyway soon leaves, curves westward, and descends toward Alabang-Zapote Road. Alabang Exit is the terminus of the expressway from 1969 to 1976, before the Alabang Viaduct was built and extended until Calamba Exit. It is also the site of the former Alabang Toll Barrier prior to the division of the entire SLEX into two concessions namely the Skyway System and SLTC-SLEX (formerly PNCC-SLEX). It climbs over the Maharlika Highway (National Road or Manila South Road) through the Alabang Viaduct, before it descends and becomes the Alabang-Calamba-Santo Tomas Expressway (ACTEx) or SLEX Main.

Dr. Jose P. Rizal Highway

From Kilometer 28.387 at San Pedro, Laguna southwards,^[2] the Dr. Jose P. Rizal Highway segment runs through the province of Laguna, as well as a segment of Carmona at Cavite province before continuing back to Laguna from Biñan towards the exit at Calamba through the Maharlika Highway. The highway was also part of the Osmeña Highway until 1992 when R.A. 6760 was amended, which named the segment after the Philippines' national hero, Dr. Jose Rizal.^[2] The road starting from Alabang Viaduct in Muntinlupa up to Santo Tomas, Batangas forms the South Luzon Tollway, handled by the South Luzon Tollway Corporation, a joint venture of the Philippine National Construction Corporation and the SMC-backed Citra group of Indonesia.^[3]

SLEX Main, Alabang-Calamba-Santo Tomas Expressway/South Luzon Tollway

Called as SLEX Main, South Luzon Tollway (SLT), or ACTEx as the alternate name for the part of the R-3 held by South Luzon Tollway Corporation. The ACTEx name refers to the segment of the two SLEX concessions from Alabang Exit in Muntinlupa up to Santo Tomas Exit in Santo Tomas, Batangas.

South Luzon Expressway in Carmona.

SLEX Main/ACTEX start past Filinvest Exit (Exit 23), with 2 to 4 lanes per direction and mostly paralleling the four-lane Maharlika Highway (National Highway, National Road or officially Manila South Road/MSR) over Muntinlupa and northwestern Laguna.^[4] The road slightly curves over barangays Bayanan and Putatan on Muntinlupa. The expressway's first service area, Tollway Plaza, having a Shell gas station and several restaurants such as Jollibee, KFC, Greenwich, Burger King, and others, is also located on this segment. Past that service area, South Luzon Expressway mostly follows a straight course, passing the interchange serving the newly opened Muntinlupa–Cavite Expressway, the Maharlika Highway, and barangays Poblacion and Tunasan in Muntinlupa.

It soon enters Laguna at San Pedro, continuing as a straight roadway lined with billboards and passing through the city's residential and industrial areas before curving and ascending past the Petron and Caltex service areas to clear Pacita Avenue and the disused spur of the PNR South Main Line. South Luzon Expressway soon enters Biñan, passing near Southwoods, Barangay San Francisco (Halang), and Splash Island, before entering Carmona, Cavite. It passes through Carmona in about one kilometer, with an exit to serve the town proper, before re-entering Biñan at Santo Tomas Bridge. The first route marker for AH26 is found on this segment. Returning to Binan, the road runs straight over Barangay Santo Tomas (Calabuso), and enters Barangay Mamplasan, with an exit to serve Laguna International Industrial Park, and several residential communities such as Brentville and Jubilation. A Caltex service is found on the southbound expressway over Mamplasan. It soon enters Santa Rosa, Laguna on a straight route, mostly lined with tress. It intersects Santa Rosa-Tagaytay Road to Santa Rosa city proper and Tagaytay through a partial cloverleaf interchange. South Luzon Expressway reduces into 3 lanes, having guard rails as the median divider. The road passes near Enchanted Kingdom and ETON City, which is within the limits of barangay Don Jose, Santa Rosa, Laguna. A Total service area lies beside the northbound lanes of the expressway. South Luzon Expressway enters Cabuyao, passing near Malayan Colleges Laguna (formerly the location of the warehouses owned by the defunct Uniwide Sales Inc.) and Santa Elena Golf and Country Club. It crosses the San Cristobal River and enters Calamba, being on a straight route until Batangas/Calamba Exit. The road approaches the Calamba toll plaza, widening to 18 lanes (including the lanes on the second southbound toll plaza and the northbound lanes), before returning to 3 lanes per direction. It passes through barangays Mayapa, Batino and Prinza before approaching Batangas/Calamba Exit. At Batangas Exit (exit 50), AH26 leaves the expressway and follows again the Maharlika Highway/Manila South Road. Calamba Exit was the former terminus of the South Luzon Expressway from 1976 to 2010, when the expressway is extended to connect with STAR Tollway and bypass the congested Pan-Philippine Highway/Maharlika Highway over Turbina.

Calamba–Santo Tomas segment of SLEX looking south towards STAR Tollway

Past Calamba Exit, the expressway narrows to 2 lanes per direction, with no exits. South Luzon Expressway, also called the Alabang-Calamba-Santo Tomas Expressway, follows a curved route paralleling the Pan-Philippine Highway (Maharlika Highway or Manila South Road) from Calamba to Santo Tomas, Batangas. It approaches the Ayala Greenfield toll plaza, continues over barangay Saimsim, and then enters Batangas on Siam-siam Bridge. A few meters after it is the location where a future Toll Road 4 will be located. The expressway curves before it ends at kilometer 57.2, continuing toward Batangas City as the STAR Tollway. However, the kilometer count of the next expressway after the Santo Tomas exit instead starts at kilometer 60.

Rehabilitation and opening of connection with STAR Tollway

SLEx-Calamba segment in 2007, prior to the rehabilitation work completion.

Prior to rehabilitation, the South Luzon Expressway was mostly an expressway with a grass median, and 2 lanes per direction from Alabang to Calamba. Rehabilitation work started in 2006, with heavy traffic brought by construction work. Alabang Viaduct is widened to 4 lanes, and the construction of Skyway Stage 2 caused traffic on the Nichols-Alabang segment. Rehabilitation work was finished in 2009, and the Alabang-Calamba segment was expanded to 3 to 4 lanes.

On 2010, an extension of the expressway, named Alabang-Calamba-Santo Tomas Expressway or ACTEx was opened, eventually connecting South Luzon Expressway to the STAR Tollway.

The Toll Road 4 or TR4 is a 61 km (38 mi) extension of SLEX from Santo Tomas in Batangas to Lucena, or Tayabas in Quezon. Construction is divided into 5 segments. The extension project is implemented by the Toll Regulatory Board and will be operated by the South Luzon Tollway Corporation (SLTC). The extension will decongest the existing national road between Santo Tomas and Lucena and provide a modern alternate route for travellers from Quezon and Bicol Region. Right of way for the expressway is acquired for the first three segments between Santo Tomas and Tiaong, and ongoing for the remainder between Tiaong, Candelaria and Tayabas. Right of way acquisition is ongoing as of 2018, with notices sent to affected landowners in Santo Tomas and Alaminos.^[7] The future expressway will start near the Ayala Greenfield toll plaza in Calamba in Calamba rather than in Santo Tomas.

If completed, the extension will have these exits:

Skyway Stage 3 / NLEx-SLEx Connector Road (Segment 11)

Two proposals for connecting the SLEx with the North Luzon Expressway (NLEx) have been under consideration by the government since 2010.^[8] According to then-DPWH Secretary Rogelio Singson both proposals would be pushed through, as the proposals can co-exist as the projects service two different corridors of the metro.^[9] On May 23, 2012, both companies presented their proposals to then-President Benigno S. Aquino III. The administration then announced through then-Communications Secretary Ricky Carandang that they hoped both companies could be given formal awarding and final approval by the end of the year, so that they could begin "by the end of this year or early next year.",^[8] Construction began in 2018.

SLEX Extension to Matnog, Sorsogon (Toll Road 5/Quezon-Bicol Expressway)

Dubbed as Toll Road 5/Quezon-Bicol Expressway, the South Luzon Expressway will be extended to Matnog from Lucena, Quezon. The total length of the extension will be 430.1 kilometers. The extension will decongest Andaya Highway and Pan-Philippine Highway, cut travel time from Manila to Naga City by 2–3 hours, and to Matnog by 6 hours and soon be built by Manila Toll Expressway Systems Inc., a company owned 40 percent by Philippine National Construction Corp. The rest is shared equally by the local firm Alloy Manila Expressway Inc. and the SMC-backed Citra Group of Indonesia which bought the shares formerly owned by the MTD Capital Berhad of Malaysia. As of 2015, the extension is discussed by Albay Gov. Joey Salceda, Toll Regulatory Board chairman Edmund Reyes, San Miguel Corporation and Ramon Ang.^[12] However on April 27, 2017, San Miguel Holdings Corporation and the Philippine National Construction Corporation under its joint venture to implement the Toll Road 5 as part of the P 554 billion Toll Road Expansion.^[13]

Service areas

Caltex service area in Mamplasan, Biñan, Laguna

The South Luzon Expressway has 8 service areas, with 4 on each direction. Most of the service areas occupy large land areas and have restaurants and retail space, with the exception of two service areas near Silangan Exit, which are simply Petron gas stations, both opened in 2016, with no other shops other than a San Mig Food Ave convenience store and car repair services. The service areas also provide ETC reloading for Autosweep RFID users.

Lay-bys

The South Luzon Expressway also has lay-bys, or emergency parking areas where motorists can stop for safety checks on their vehicles and other emergencies.
