context_page_description: San Antonio, officially the City of San Antonio, is the seventh-most populous city in the United States, and the second-most populous city in both Texas and the Southern United States, with 1,547,253 residents in 2019. Founded as a Spanish mission and colonial outpost in 1718, the city became the first chartered civil settlement in present-day Texas in 1731. The area was still part of the Spanish Empire, and later of the Mexican Republic. It is the state's oldest municipality, having celebrated its 300th anniversary on May 1, 2018.
  The city's deep history is contrasted with its rapid growth over the past few decades. It was the fastest-growing of the top ten largest cities in the United States from 2000 to 2010, and the second from 1990 to 2000. Straddling the regional divide between South and Central Texas, San Antonio anchors the southwestern corner of an urban megaregion colloquially known as the "Texas Triangle". The Greater San Antonio and Greater Austin areas are separated from each other by 80 miles along Interstate 35.
  San Antonio serves as the seat of Bexar County; San Antonio is the center of the San Antonio–New Braunfels metropolitan statistical area.
context_section_description: A bus and rubber tired streetcar (bus) system is provided by the city's metropolitan transit authority, VIA Metropolitan Transit. VIA's full fare monthly unlimited Big Pass is $38 per month. VIA began operating a bus rapid transit line known as VIA Primo in December 2012, which connects Downtown San Antonio to the South Texas Medical Center, the main campus of the University of Texas at San Antonio, and the independent enclave city of Leon Valley.
  In August 2010, VIA Metropolitan Transit unveiled buses that are powered by diesel-electric hybrid technology.
  The 30 hybrid buses were put into service on VIA's express routes to serve daily commuters across the city. This set of buses follows the introduction of new vehicles powered by compressed natural gas, which were unveiled in May 2010. In the fall of 2010, VIA took delivery of three new buses that are powered by electricity from on-board batteries. These buses serve the Downtown core area, and are the first revenue vehicles VIA operates which have zero emissions.
  VIA offers 89 regular bus routes and two Downtown streetcar routes. This includes express service from Downtown to park and ride locations in the south, west, northwest, north central and northeast sides of the city, with service to major locations such as UTSA, Six Flags Fiesta Texas and SeaWorld. VIA also offers a special service to city events including Spurs games and city parades from its park and ride locations. VIA has, among its many routes, one of the longest local transit routes in America. Routes 550 (clockwise) and 551 (counterclockwise) travel 48 miles (77 km) one way as they loop around the city.
