en.Wedoany.com Reported - The Lanfeng section of China's Yanhuang Expressway has opened to traffic, and the Dongbatou Yellow River Bridge has been put into use, marking the full completion of the Henan section. At midnight on June 16, the Lankao to Fengqiu section of the Yanhuang Expressway (referred to as the Lanfeng Expressway) was opened for operation. The Dongbatou Yellow River Bridge, a core control project of the Lanfeng Expressway constructed with participation from China Railway Group Limited's subsidiary China Railway Hi-Tech Industry Corporation, was officially put into service, thus achieving full connectivity of the Henan section of the Yanhuang Expressway.
The Henan section of the Yanhuang Expressway has a total length of approximately 320 kilometers. The Lanfeng Expressway starts at Guying Town in Lankao County and ends at Pandian Town in Fengqiu County, with a total length of 30.263 kilometers. It features a two-way six-lane configuration with a design speed of 120 kilometers per hour. The Dongbatou Yellow River Bridge is located at the final bend of the Yellow River's nine bends and eighteen turns—Dongbatou in Lankao. It has a total length of 9,104 meters. The main bridge is a (140+360+360+140) meter steel-concrete composite girder three-tower cable-stayed bridge, with a Ding-style cable tower: the middle tower is 160.5 meters high, and the side towers are 154.3 meters high. The auxiliary bridge, consisting of 20 spans of 100-meter steel-concrete composite girders, is the largest of its kind in China. The east levee-crossing bridge has a total length of 280 meters, adopting a 140-meter plus 140-meter single-tower double-cable-plane tower-girder consolidation system steel-concrete composite girder cable-stayed bridge. The bridge establishes a rapid connection channel between Lankao and Fengqiu, significantly improving the efficiency of cross-river travel for the public, reducing the travel time between the two locations from 1 hour to 20 minutes. China Railway Hi-Tech Industry Corporation's China Railway Jiujiang Bridge Co., Ltd. is primarily responsible for the manufacturing and installation of approximately 23,300 tons of steel girders for the main bridge and the east levee-crossing bridge.
The Lanfeng Expressway is the first key project to be completed and put into operation in Henan Province after the province's total expressway mileage exceeded 10,000 kilometers. It forms an east-west backbone corridor parallel to the Lianhuo Expressway, which is of great significance for implementing the strategy of the rise of central China, promoting high-quality development of the Yellow River Basin, accelerating the construction of the "Central Plains Urban Agglomeration," and driving regional economic development along the route.
