South Luzon Tollway (SLT), popularly called SLEX, runs between the Skyway System which comprises the elevated section and the ground level road, and STAR Tollway.   Until its reconstruction by the South Luzon Tollway Corp. (SLTC), it was a 28 km., 4-lane expressway from Alabang Viaduct in Muntinlupa to Brgy. Turbina in Calamba. It has since been widened to 8 lanes from Alabang Viaduct to Sta. Rosa, and 6 lanes to Brgy. Turbina, and extended by 8 kms. to Sto. Tomas, Batangas where it now links up with STAR Tollway.

SOUTH LUZON TOLLWAY CORP (SLTC) is a joint venture company of MTD Manila Expressways, Inc. and the Philippine National Construction Corp (PNCC).  By virtue of a Supplemental Toll Operation Agreement (STOA) entered into with the Philippine government, SLTC, as the Investor, committed to undertake all works required for the SLEX Project including its total financing without sovereign guarantees, and with the recovery of its investment being in the form of the collection of toll by the Manila Toll Expressway Systems, Inc. (MATES), its operation and maintenance (O&M) company. 

Per agreement the project has two (2) phases – Phase 1 comprised the road from the Alabang viaduct (Toll Road 1) up to Calamba, Laguna (Toll Road 2), and from Calamba, Laguna to Sto. Tomas, Batangas (Toll Road 3). Original project cost for Phase 1 is Php. 8.5 B.

Phase 2 consists of a new roadway from Makiling , Laguna to Lucena, Quezon Province. Engineering works for phase 2  have yet to commence.

The SLTC concession period – SLTC was granted a 30-year concession period from February 2006 (date of signing of the STOA and approval thereof by the President of the Republic of the Philippines) to February 2036. It includes the period of construction which began in June 2006.

The SLTC Operation and Maintenance – Under the STOA, MATES, has the mandate to automatically take over the operation and maintenance of SLT upon expiration of the PNCC franchise in April 2007. PNCC continued to operate SLEX up to May 2, 2010.

SLTC assumed operations/toll collection on May 2, 2010 – Since its concession began before the project construction period, SLTC has only 25 years left for investment recovery when its O&M company MATES assumed operations in May 2, 2010. .

Prior toll rate was lowest in the country, current toll rate is in mid-range –  The basic toll fee collected by SLTC from May 2010 to Dec. 2010 was Php 0.76 per km. for class 1 vehicles. This was the toll fee for the old, unrehabilitated SLEX and it was the lowest of the toll rates charged by all other tollways, including those built by government or by government with supplemental foreign funding.

TRB granted SLTC an initial toll rate of Php 3.02 per km for implementation on January 1, 2011. It was implemented by SLTC on April 1, 2011.

The SLEX project is totally financed by the Malaysian investor, MTD Capital Bhd. It has no government guarantee or local funding.
