The largest-span swivel bridge in the expressway system in northwest China's Xinjiang Uygur Autonomous Region successfully underwent its rotation maneuver on Tuesday.

Located in Shanshan County of Turpan City in Xinjiang, the construction of the swivel bridge is part of the extension project on G30 Expressway, which connects Lianyungang City in east China's Jiangsu Province to the China-Kazakhstan border at Khorgos in Xinjiang.

The rotation was accomplished in 70 minutes at a millimeter-level precision, with a counterclockwise turn of 61 degrees.

The extension project, which links Hami and Tuyugou in Xinjiang, is 345-kilometer-long. After completion of its construction, the project is expected to significantly improve road traffic efficiency of the regional road network.
