On July 1 next year, Shanghai Yangtze River Bridge will be opened to traffic, and Yangzhou motor train will reach Shanghai

Shanghai to Nantong railway is a high-speed railway connecting Shanghai and Nantong, which is one of the main channels of "eight vertical and eight horizontal" high-speed railway in the national "medium and long term railway network planning", and an important part of "coastal channel". After completion, it will be seamlessly connected with Ningqi railway, Yantong high speed railway, Qingyan salt railway and Qingyan Weirong intercity railway, enhance Shanghai's radiation capacity to the central Jiangsu and Northern Jiangsu areas, integrate key towns along the Yangtze River "yangtaitong" into the Yangtze River Delta Intercity network, and form a fast, safe and efficient passenger transport network. The speed of

Nanjing Qidong railway and Shanghai connect railway is 200 kilometers per hour, which is designed according to the national railway I standard. After the completion of Shanghai connect railway, it will meet with Nanjing Qidong railway in Nantong. In this way, a ring railway network of southern and Northern Jiangsu is formed, which is "Shanghai Suzhou Wuxi Zhenjiang Nanjing Yangzhou Taizhou Nantong Shanghai". In the future, the motor car of Benz on Ning Qi railway can be directly turned to Shanghai connect railway. Yangzhou takes only three hours by train to Shanghai.

at the construction site of the main channel bridge of the Shanghai Tongjiang bridge, with a track laying locomotive steadily pushing the 25 meter track to the place, the main channel bridge of the Shanghai Tongjiang bridge officially entered the stage of track laying construction. The 11072 meter long Shanghai to Yangtze River Bridge of

is a "three in one" river crossing channel. As a highway railway bridge, the upper layer of the bridge is a six lane Xitong Expressway Crossing the river; the lower layer is a railway layer with four railways. In the "four lines", the downstream two lines are the river crossing section of Shanghai Tongjiang railway, the main line of national railway, and the upstream one is the river crossing section of Yantong high-speed railway. The day before yesterday began to lay for the Shanghai to Shanghai railway across the river. Before the track laying operation of

, CRBC has laid ballast on the steel bridge surface of the railway layer to protect the steel bridge surface and carry the track.

this time, PG28 track laying machine is used to lay the tool track. The tool track is mainly used for the transportation of materials and personnel. After the completion of the basic engineering construction of the track line, the temporary tool track will be replaced with each 500m long track, and each 4 tracks will be welded as a whole. The drop weight test and ultrasonic flaw detection will be carried out at the long track welding position to ensure the safety of high-speed rail operation Integrity.

it is expected that on the 20th of this month, the temporary tracks of the main channel bridge of Shanghai Tongjiang River Bridge will be laid completely, and then the train control system will be installed on the railway layer of the bridge. Crdaqiao Institute, the bridge designer, and the construction company will make the second precise adjustment on the tension of 432 stay cables to make the bridge line meet the design requirements. Brief introduction of

Shanghai to Yangtze River Bridge. The main bridge of the bridge is a steel truss girder cable-stayed bridge with a main span of 1092 meters. It is the largest cable-stayed bridge with both highway and railway in the world and the first one with a span of more than 1000 meters in the world. The

project was started on March 1, 2014 and closed on September 20, 2019. The bridge is planned to reach the static acceptance condition on March 20 next year, and the whole bridge will be opened to traffic on July 1. As an important part of the coastal high-speed railway in the national eight vertical and eight horizontal railway network, the

Shanghai to Yangtze River Bridge is a common river crossing channel of Shanghai to Shanghai railway, Sujia intercity railway and Xitong expressway. After the bridge is opened to traffic, it will become an important railway and highway crossing the river in the coastal area, which will be conducive to accelerating the construction of China's coastal railway fast track and promoting the economic integration process of the Yangtze River Delta urban agglomeration.
