E2 expressway (Philippines)

Expressway 2 (E2) forms part of the Philippine expressway network. Its main route runs from Makati to Santo Tomas as the South Luzon Expressway and from Santo Tomas to Batangas City as the STAR Tollway. It has spurs also signed as E2.^[1] South Luzon Expressway's section from Makati to Calamba, including the Skyway from Makati to Muntinlupa, is also part of AH26.^[2]

E2 starts at Magallanes Interchange in Makati as South Luzon Expressway. From Makati to Calamba, it is a part of Asian Highway 26 (AH26). It carries Skyway until it reaches Muntinlupa, where it ends as SLEX continues. Differing in concession holders, its section between Magallanes and Alabang Exit is also known as Skyway At-Grade, while the rest of the section takes the South Luzon Expressway concession branding. It parallels Manila South Road (N1) from Muntinlupa to Calamba until it reaches Calamba Exit, a partial cloverleaf interchange in Calamba where N1 takes the AH26 concurrency. It continues until it reaches Santo Tomas, which ends and becomes the STAR Tollway. However, a spur of SLEX will continue set to be part of E2.^[3]

The extent of E2/AH26 on the Skyway is unknown since the Department of Public Works and Highways's ArcGIS app does not show any route designation for the elevated tollway.^[1] However, some E2/AH26 markers were seen exclusively on Skyway Stages 1 and 2, between Buendia Exit in Makati and South Station (Alabang–Zapote) Exit in Muntinlupa until they were dismantled together with the center barriers in 2020.

E2 continues as STAR Tollway at Santo Tomas Exit, an interchange with Maharlika Highway (N1) and SLEX in Santo Tomas, Batangas. It traverses from Santo Tomas to Batangas City, ending at a roundabout and four-way interchange with Jose P. Laurel Highway (N4) and Batangas Port Diversion Road (N434).

Muntinlupa–Cavite Expressway is a 4-kilometer (2.5 mi) expressway in Muntinlupa that connects SLEX and Daang Hari Road near Bacoor, Cavite. It is currently the shortest expressway in the Philippines.^[4]

A 7.7-kilometer (4.8 mi), four-lane elevated expressway that connects the NLEX Harbor Link to the Metro Manila Skyway. It traverses Manila and Caloocan. This serves as the northernmost spur of the E2 Expressway
