Since 1951, Tibet has gradually built a comprehensive transport network composed of highways, railways, air routes, and pipelines. Highways with a total length of 118,800 km have been built, providing access to all administrative villages in the region. Ninety-four percent of towns and 76 percent of administrative villages have direct access to asphalt and concrete roads. Some 700 km of expressways and grade-one highways are in service. The Qinghai-Tibet Railway and the Lhasa-Xigaze Railway have been completed and opened to traffic. The construction of the Sichuan-Tibet Railway has begun. A number of feeder airports have been built, including Bamda Airport in Qamdo, Mainling Airport in Nyingchi, Peace Airport in Xigaze, and Gunsa Airport in Ngari. Tibet now has 140 domestic and international air routes in operation, reaching 66 cities.
With a modern communications network mainly consisting of optical cables and satellites, Tibet is part of the information expressway. All administrative villages have mobile phone access, and optical cable broadband coverage has reached 99 percent. Before 1951, Tibet had only one hydropower station, which supplied electricity only to a handful of aristocrats. Now, a comprehensive energy network is in place, with hydro power as the mainstay, supplemented by solar, wind, and geothermal power. In 2020, Ngari Prefecture was connected to the central Tibet power grid, completing the full coverage of the main power grid across the whole of Tibet.
