North Luzon Expressway (NLEX): from Balintawak, Quezon City, this highway cuts through the province of Bulacan and ends in Mabalacat, Pampanga. It will possibly be extended to connect the Santa Ines Terminus with SCTEX Dolores Interchange to decongest the Clark Spur Road, allowing the motorists going to and from provinces of Northern Luzon to access the NLEX directly from SCTEX Dolores Interchange. Formerly, it was dilapidated since late 1960s. It went major overhaul and it is now a world-class highway.
South Luzon Expressway (SLEX): from Magallanes, Makati City to Santo Tomas in Batangas. This is considered as the most important infrastructure serving the industrial area of Calabarzon. It has been overhauled to decongest traffic and extended from Calamba Terminus to Santo Tomas to connect it with STAR Tollway. It will be extended 55 kilometers further to Lucena City in Quezon to have a fast travel time.
Metro Manila Skyway: considered as a separate elevated highway from its base, SLEX, the existing 10-km portion serves motorists from Buendia, Makati City to Bicutan, Parañaque City. It is being extended to Alabang to further decongest the Nichols-Alabang stretch of SLEX, which could no longer be widened due to land area constraints. Extension to Balintawak, passing above PNR tracks is being planned to connect it with NLEX and to decongest many of north-south major roads in Metro Manila. Upon completion, it will be a 35-km elevated highway traversing the whole Metro Manila from Alabang, Muntinlupa City to Balintawak in Quezon City.
Manila-Cavite Expressway (CAVITEX')': from Baclaran, Parañaque City to Bacoor, Cavite. This highway offers a wonderful view of Manila Bay and the Manila skyline. It is being extended to Noveleta to decongest some of its major thoroughfares and have a fast travel time.
Subic-Clark-Tarlac Expressway (SCTEX): It was completed in 2008 and it has a direct link from the Subic Bay Freeport in Zambales Province (connecting the existing Subic-Tipo Roadway) to the Clark Special Economic Zone in Pampanga and up to the Luisita Industrial Complex in Tarlac City. It is currently connected to NLEX via Clark Spur Road but there are plans to have a direct connection. SCTEX Clark-Tarlac portion is the logical extension of the NLEX.
Southern Tagalog Arterial Road (STAR Tollway): from Sto.Tomas, province of Batangas to Batangas City. It is now connected to the SLEX, it will easily transfer people and goods from Manila to the port city of Batangas.
Tarlac-Pangasinan-La Union Expressway (TPLEX): from the Tarlac terminus of SCTEX to Rosario, La Union. This expressway is now under construction to further decongest the Manila North Road and to reduce travel time. This is also the logical extension of NLEX.
Northeast Luzon Expressway (NELE): It is a proposed expressway from Quezon City to Tuguegarao City in Cagayan. This highway will serve as the backbone for the Cagayan Valley and East Central Luzon.
Cebu Trans-Axial Expressway: It is a proposed expressway that will serve as the backbone of Cebu Island.
