China National Highway 109 connectsBeijing withLhasa. It runs westwards from Beijing viaDatong,Yinchuan andXining toGolmud before turning southwest to Lhasa. The portion of the highway fromXining toLhasa is known as theQinghai-Tibet Highway.[1] The total length of the route is 3,901 km.
Fushi Road or Jinglan Road forms the stretch of G109 in Beijing, as it begins fromFuchengmen and traverses throughShijingshan. The majority of the Beijing section is inMentougou District.
The section of the highway within westernQinghai andTibet, fromGolmud toLhasa, is paralleled by theQinghai-Tibet Railway. The highway reaches its highest elevation of 5,231 meters (17,162 ft) atTanggula Pass. Construction of this section started on 11 May 1954.[2]
"Tasked with carrying upwards of 85 per cent of goods in and out of Tibet, the Qinghai-Tibet Highway has been dubbed the "Lifeline of Tibet." ... Since it was opened to traffic in 1954, the central government has spent nearly 3 billion yuan (US$362 million) on three major overhauls. It was asphalted in 1985."[3]
The route also holds importance as one of the main coal transport routes in southernInner Mongolia.[4]
