Zhengzhou, December 17 (Xinhua) -- 117 years ago, the Jinghan Railway was completed in its entirety, and a steam train emitting white smoke and whistles crossed the Yellow River Railway Bridge in Zhengzhou for the first time. Recently, not far from it, a high-speed railway with a speed of 350 kilometers per hour roared over the new bridge, connecting the two provincial capitals of the Central Plains for the first time.
On December 8, the Jinan-Puyang section of the Jinan-Zhengzhou high-speed railway was completed and opened to traffic, marking the completion of the Jinan-Zhengzhou high-speed railway, which is 407 kilometers away from Jinan west to Zhengzhou east, realizing 1 hour and 43 minutes of direct access, ending the history of detour.

The route crosses the Yellow River, the second largest river in China. Zhengzhou Wantan Yellow River Highway and Railway Bridge is one of the most difficult projects on the whole line, the bridge is 4,377 meters long, in the form of highway and railway, and has the traffic role of high-speed rail, intercity railway and highway "three bridges in one", and has now become a new landmark on the Yellow River.
The long span and fast speed are the biggest challenges of the Yellow River Highway and Railway Bridge in Wantan, Zhengzhou. Xu Xudong, chief engineer of Henan Intercity Railway, said that nearly 30,000 data were collected per kilometer of line on the bridge, so that the track fine-tuning error was controlled at 0Within 5 mm, combined with the self-created constant pressure drip irrigation maintenance system, improved and upgraded track plate fine adjustment and pressing device, plate seam foam board double fixing device and other tooling processes, to ensure that the train passes through the bridge at a speed of 350 kilometers per hour without slowing down, so the Wantan Yellow River Highway and Railway Bridge has the largest single scale on the Yellow River and the highest operating speed.
A small "apostrophe" on the Yellow River is a major breakthrough in the transportation pattern of the Yellow River Basin. Henan has become the first province in the country to build a high-speed rail network in the shape of a "meter", and high-speed trains from Zhengzhou can directly reach 370 cities across the country.
A hundred years ago, the relationship between Zhengzhou, the hinterland of the Central Plains, and the Yellow River Railway Bridge changed the urban transportation of the ancient city of Zhengzhou and changed the development pattern of the Central Plains urban agglomeration.
This is the Zhengzhou Yellow River Railway Bridge (data**) issued by Xinhua News Agency.
Built in September 1903 as China's first railway bridge across the Yellow River, the Zhengzhou Yellow River Railway Bridge was no easy task in the course of the Yellow River, which had high sand content, fierce water potential and erratic rolling.
The opening of the Jinghan Railway was determined by the opening of the Zhengzhou Yellow River Railway Bridge, which operated at a speed of less than 15 kilometers per hour, but broke the traditional transportation pattern of China's historical reliance on waterways and post roads.
The iron bridge crossed the moat, with the "power of a bridge", so that the unknown Zhengzhou developed into a "northern metropolis", the north and south logistics converged, accelerated the development of Zhengzhou's industry and commerce, and then Zhengzhou's political, economic and military status was improved, becoming a strategic town in the central region, this city known as the train pulled, into the national vision.
Located in the Central Plains, the throat of the north and south, the Zhengzhou Yellow River Railway Bridge used to be the focus of contention and counter-contention, sabotage and anti-sabotage. "Zhengzhou Cultural and Historical Materials" editorial committee staff introduced, from 1949 to 1952, the relevant departments have been reinforced many times on the bridge, but there is a large gap between the transportation capacity and traffic demand, in 1958, the Yellow River appeared a huge flood peak, the bridge was seriously damaged, and gradually withdrew from the stage of railway history.
The seriously ill bridge did not disappear, in July 1987, the Zhengzhou Yellow River Railway Bridge began to be demolished, the south end of the 5 holes 160 meters bridge body as a historical relic retained, set up a monument to commemorate, now tourists walk on the bank of the Yellow River, pass by the ruins of the old bridge, see the piers standing, can not help but look a few more.
Today, there are 10 bridges connecting the banks of the Yellow River in Zhengzhou. After the opening of the Jinan-Zhengzhou high-speed railway, some experts said that the connection of the bridge will allow the two provincial capitals of Jinan and Zhengzhou with a GDP of trillions to be directly connected, and the two cities "1The "5-hour metropolitan area" is beginning to take shape, and the flow and cohesion of resource elements between cities will also be accelerated, providing strong support for the two cities to deepen cooperation, complement each other's advantages, and promote the ecological protection and high-quality development of the Yellow River Basin.
According to statistics, by the end of 2022, the total number of railway bridges in China was about 920,000 seats, with a cumulative mileage of 310,000 km. Whether it is crossing capacity, bridge technology or bridge construction materials, China's bridges have reached the world-class level.
At present, the preserved iron bridge piers are accompanied by the surging water of the Yellow River, connecting the century-old history, as if telling the glory and dream of an iron bridge over the Yellow River.
