SMC SLEX Inc. is the concessionaire of the SLEX which currently spans 36.1 km from Alabang, Muntinlupa to Sto. Tomas, Batangas. The SLEX is one of the three major expressways that links Metro Manila to the key southern provinces of the Philippines, including CALABARZON. To the north of the SLEX is the Skyway System, and to the south is the Southern Tagalog Arterial Road ("STAR"). SLEX connects with Skyway System and STAR and is a key logistical backbone to the southern corridor of Metro Manila.
SLEX is composed of four project toll roads, three of which are currently operational. Under the concession, each project toll road required rehabilitation and/or construction works of the different segments of SLEX:
Project Toll Road 1 ("TR 1"): The Alabang Viaduct - 1.2 kms
TR1 involved the rehabilitation and upgrade of the Alabang viaduct which included the widening of third-grade portion of the roads, retrofitting of the existing structure, and the replacement and expansion of the elevated portion from 6 to 8 lanes.
Project Toll Road 2 (“TR 2”): Expansion from Filinvest Exit to Calamba, Laguna – 27.3 kms
TR2 involved the widening of the SLEX segment between Filinvest exit and Sta. Rosa, Laguna from 4 to 8 lanes and segment between Sta. Rosa, Laguna to Calamba, Laguna from 4 to 6 lanes.
Project Toll Road 3 (“TR 3”): Extension of the SLEX to Sto. Tomas, Batangas – 7.6 kms
TR3 involved the construction of a 4-lane roadway from Calamba, Laguna to Sto. Tomas Batangas. The construction of this section connected Metro Manila, SLEX, and STAR.
FUTURE PROJECTS / EXPANSION:
Project Toll Road 4 (“TR4”)
TR 4 involves a 4-lane roadway extension of TR 3 from Sto. Tomas, Batangas to Lucena City, Quezon with a length of 57.04 km (4-lane toll road).
