Liuwu Bridge

The Liuwu Bridge links central Lhasa to Lhasa Railway Station and the newly developed Niu New Area of Doilungdêqên County on the south bank of the Lhasa River. Residents in the Ne'u area were resettled to make way for the new development.[1] The 42 square kilometres (16 sq mi) "Liuwu New District" includes new residential buildings in traditional Tibetan style. The villagers, numbering almost 1,700, were moved into these buildings. The effect of the railway, bridge and Liuwu New District development has been urbanization and development of new enterprises such as transport, retail outlets and restaurants.[2]

The Liuwu Bridge was built by China Communications Construction.[3] The construction project began in 2004.[4] About 500 people worked on the bridge, but according to an Agence France-Presse correspondent even the laborers engaging in sweeping and pushing wheelbarrows were almost all Chinese, since the chief engineer said Tibetans "do not have the technical training needed for the task."[5] The bridge was completed in April 2007.[6][7] It was opened to traffic on 1 May 2007.[8] Total funding allocated to the project was RMB 388.51 million.[4]

The bridge is one of the notable structures of the 1,142 kilometres (710 mi) Qinghai–Tibet Railway, the highest railway in the world.[9] It is the first urban overpass in the Tibet Autonomous Region.[3] The total length is 1,600 metres (5,200 ft) and the elevated section is 1,373 metres (4,505 ft).[4] The main span has a duplex basket-handle arch with a heeling angle of 28.4 degrees and an arch length of 120 metres (390 ft). The piers of the main bridge use piled underground diaphragm walls.[3] The bridge is 29 metres (95 ft) wide, with three lanes in each direction.[4] The structure includes the first cloverleaf junction in Tibet.[10]
