China Railway news. On October 11, a EMU detection vehicle sped past the huaizhen section of Lianzhen railway. According to reports, since September 1 this year, the world's first high-speed railway suspension bridge - Wufengshan Yangtze River Bridge has been tested for more than a month, and the overall effect is stable, which also marks a step closer to the opening of the whole Lianzhen railway, and the experimental capacity can reach the standard requirements of class 0.5 aircraft

the Wufengshan Yangtze River bridge across the Zhenjiang section of the Yangtze River, located between the Runyang Yangtze River Bridge and the Taizhou Yangtze River Bridge, is a key control project for the southern extension of the Zhenjiang railway and the Beijing Shanghai Expressway, and is also the most difficult project for the construction of the whole line. The bridge connects Dantu District of Zhenjiang City and Zhenjiang New Area from north to south, with a total length of 6409 meters, of which the main span is 1092 meters. It adopts a single span suspended steel truss suspension structure, and the upper layer is a two-way 8-lane expressway, with a design speed of 100 kilometers per hour; The lower level is a four line high-speed railway with a design speed of 250 kilometers per hour

it is reported that the Wufengshan Yangtze River Bridge was officially started on October 28, 2015, when the test was conducted. It is the third highway and railway dual-purpose bridge in Jiangsu section of the Yangtze River after Nanjing Yangtze River Bridge and Shanghai Sutong Yangtze River Bridge. After the completion of the bridge, it is not only the first highway railway suspension bridge in China, but also the highway railway suspension bridge with the fastest operation speed and the largest operation load in China. At the same time, it is the world's first high-speed railway suspension bridge and the highway railway suspension bridge with the largest span, the fastest operation speed and the largest operation load that has been built in the world

as a world-class long-span heavy haul high-speed railway dual-purpose suspension bridge, Wufengshan Yangtze River Bridge adopted a series of new structures, new materials, new processes, new technologies and new equipment in the construction process, and obtained more than 20 patents. Compared with similar bridges, it has also set a number of domestic and world records in terms of anchorage scale, caisson construction, bridge tower construction, etc., and its construction technology content represents the highest level of similar bridge construction in China and even the world

after the opening of Lianyungang Zhenjiang railway in the future, some counties and cities in Lianyungang, Huai'an, Yangzhou and Zhenjiang will be directly connected to the national high-speed railway, realizing the seamless connection between Northern Jiangsu and developed cities such as Shanghai and Nanjing. At that time, the travel time from Lianyungang to Nanjing will be shortened to about 2 hours, and the travel time from Lianyungang to Shanghai will be shortened to about 3 hours. Yangzhou will also enter the "era of high-speed rail", becoming the only city with high-speed rail in 13 prefecture level cities in Jiangsu Province
