The Southern Tagalog Arterial Road (also known as the STAR Tollway or CALABARZON Expressway) is a two-to-four-lane 42-kilometre (26 mi) expressway in the province of Batangas in the Philippines. It is operated by STAR Infrastructure Development Corporation (STAR - IDC). The expressway is designated as part of E2, which includes the South Luzon Expressway and Skyway.
The expressway start at the intersection with the Pan-Philippine Highway (also known as the Maharlika Highway) and the South Luzon Expressway in Santo Tomas and runs southward, near Diversion Road, to Batangas City. It passes through Malvar, Tanauan, Lipa and Ibaan.
The expressway was opened on 2001, with its first segment built between Santo Tomas and Lipa. From 2008, it was extended toward Batangas City, and from 2010, the South Luzon Expressway is connected to STAR Tollway, further shortening travel time between Manila and Batangas. The Lipa - Batangas City segment was a two-lane expressway until an addition of a second roadway between Lipa and the Ibaan-Batangas City boundary was opened in 2014. Damage on a bridge in the Ibaan - Batangas City boundary caused by Typhoon Nina (Nock-ten) required the closure of the Ibaan - Batangas City segment for bridge repairs, and diverting traffic to the parallel national roads.
With increasing traffic demand in the Batangas City - Bauan area and the Batangas Bay area, proposals to extend the expressway are laid out to decongest the existing routes through those areas. Two projects are proposed to extend the expressway to barangay Pinamucan, within Batangas City, and to the municipality of Bauan.
STAR Tollway parallels most of the route of the President Jose P. Laurel Highway, which spurs off from the Maharlika Highway at Santo Tomas towards Lipa and Batangas City, and the Ibaan-Batangas City segment of the Batangas-Quezon Road. The road mostly traverses rural barangays of the cities and municipalities it passes and also overlooks several mountains. High voltage transmission lines cross the expressway, but only in several areas, as the expressway is primarily rural.
Santo Tomas-Lipa City
STAR Tollway starts as the physical extension of South Luzon Expressway past the overpass with the abandoned Philippine National Railways (PNR) branch line to Batangas and an access road for Light Industry and Science Park III at Santo Tomas. Formerly, the toll road ended at Santo Tomas Exit before 2010. The road widens for a short distance at the Santo Tomas toll plaza before narrowing back to two lanes. The road enters Tanauan, with an exit serving the city proper from the west. Past Tanauan Exit, STAR Tollway descends on a scenic curve before ascending on approach to Malvar. A 500,000 volt transmission line of the National Grid Corporation of the Philippines (NGCP) crosses at this segment. Entering Malvar, the road mostly passes rural areas, mostly containing large coconut plantations and small residential areas. Also, within Malvar, Mount Maculot can be seen on the right of the road and Mount Malarayat can be sighted on the left. Afterwards, it enters Lipa, and the road gradually curving before approaching Lipa Exit, which is an access to the city proper, and also to the nearby towns of Mataasnakahoy, Cuenca, and Alitagtag. The exit once served as the tollway's southern terminus until 2007, when STAR Tollway was extended southward towards Batangas City.
Lipa City-Batangas City
Past Lipa Exit, STAR Tollway is mostly dual carriageway, until it narrows in approach to Batangas City. This segment was a two-lane expressway from its opening in 2008, until the second roadway opened on 2014. The roadways of this segment is concrete, with the southbound roadway the former two-lane expressway, that has been in bad condition with increased traffic demand.
South of Lipa Exit, the road mostly runs through the rural barangays of Lipa. Then, it curves slightly on approach to San Jose. At approach to Ibaan Exit, the road climbs over the San Jose-Ibaan Road before descending back to ground level. Three NGCP transmission lines cross the expressway on this area, with voltages of 230,000 and 500,000 kV before Ibaan Exit and 69,000 kV on Ibaan exit. Past Ibaan Exit, STAR Tollway mostly runs a arcing route, traversing several rural barangays of Ibaan and paralleling the Batangas-Quezon Road from Ibaan to Batangas City. The road narrows back to two lanes at Sabang bridge on the Ibaan-Batangas City boundary. The approach to Batangas City from Ibaan was a site of a fatal head-on collision between a jeep and a bus, that killed 7 on January 2011. The road becomes a 3-lane road, with a concrete jersey barrier dividing the road, ascending before following a straight course up to the STAR Tollway's southern terminus at Balagtas Rotunda. The road widens at the Balagtas toll plaza, narrows back to 3 lanes, and ends at the Balagtas Rotunda, a roundabout with Jose P. Laurel Highway, Batangas Port Diversion Road, and Batangas-Balete Road.
In an effort to link the different Southern Tagalog Provinces to the National Capital Region, the government with the cooperation of the Provincial Government of Batangas and with the technical and country developmental assistance of the Government of Japan through the Japan Official Development Assistance, made the STAR Tollway project a reality.
The STAR Tollway I, from Santo Tomas to Lipa, was opened in 2001; STAR Tollway II, from Lipa to the Batangas City Port, opened in 2008. It is fully operational for all motorists. It was opened as part of the Road Development Project of the government, linking the South Luzon Expressway to STAR Tollway onwards to the Batangas Port in Batangas City. The travel time from Manila to Batangas City became 2 hours when Stage 2 opened.
The STAR Tollway Project I and II was funded by Japan Bank for International Cooperation (JBIC) and Japan International Cooperation Agency (JICA) and implemented by the Department of Public Works and Highways - Urban Roads Project Office (DPWH - URPO).
The STAR Tollway is now under the supervision of the Toll Regulatory Board (TRB) and it is being operated by the Star Tollway Corporation.
Announced by the concessionaire, STAR-Infrastructure Development Corporation (SIDC), on May 16, 2013, the STAR Tollway Upgrading and Rehabilitation Project began on July 2013 as announced by SIDC president Melvin Nazareno. Under the project, the expressway undergone several upgrade and rehabilitation on its roads and facilities in order to cope with the traffic demand of the expressway. The expressway redevelopment included asphalting the Santo Tomas - Lipa segment, upgrading the Lipa - Batangas City segment to a four-lane divided expressway, improvements on the toll collection system, installation of closed circuit television (CCTV) cameras for traffic monitoring, and addition of lighting on some segments.  The expansion of the Lipa–Batangas City segment commenced on June 2013, and finished in June 2015 with adding of lights.
Closure of Sabang Bridge
Sabang Bridge which connects the town of Ibaan and Batangas City is closed to all traffic due to repair caused by damage of Typhoon Nina (Nock-ten), leaving Ibaan Exit to be the temporary south end of the expressway.

A 10 km (6.2 mi) extension of STAR Tollway, is proposed by the Sangguniang Panlalawigan of Batangas as two priority projects that will benefit the province as well as Mimaropa. The proposed extension will increase economic growth in the Batangas Bay area and reduce congestion on existing roads in Batangas City. The project will cost ₱576,000,000, and will pass through the barangays of Tinga Itaas, Tinga Labac, San Pedro, Dumantay, Sampaga, Sirang Lupa, and San Isidro, all in Batangas City.

|Batangas City - Bauan Toll Road|
|Length:||10 km (10 mi)|
|From:||E2 (STAR Tollway) at Balagtas, Batangas City|
|To:||Bauan - Mabini Road at Manghinao, Bauan, Batangas|
Another extension to Bauan, called the Batangas City - Bauan Toll Road, is proposed by the Department of Public Works and Highways as an alternative to the existing national road between Batangas City and Bauan. The project is expected to decongest the existing national road, whose traffic demand reached beyond capacity due to roadside establishments, industrial areas, and the Batangas Port, and increase economic development in the Batangas City - Bauan area. The proposed alignment of the toll road will start at the present terminus of STAR Tollway at barangay Balagtas, pass through the northern rural barangays of Batangas City and San Pascual, and end at the national road to Mabini at barangay Manghinao in Bauan. The project is awaiting approval as of February 2017.
