The present Yellow River Bridge from the upper reaches of the Yellow River to the middle and lower reaches of the Yellow River is as follows:

Lanzhou Yellow River Railway Bridge

Lanzhou Yellow River railway bridge, namely Zhongshan Bridge, is located at the foot of Baita Mountain in the north of Lanzhou city. It is the oldest ancient bridge in Lanzhou, Gansu Province. It is known as "the first bridge in the upper reaches of the Yellow River in the world".

The predecessor of Lanzhou Yellow River railway bridge is Yellow River floating bridge. The Yellow River floating bridge was built by Feng Sheng, Duke of Song Dynasty, 7 Li west of Lanzhou in 1372. In 1376, Deng Yu, the Duke of Wei, moved the bridge 10 Li to the west of the city, which was called "Zhenyuan bridge". In the 18th year of Hongwu in Ming Dynasty (1385 AD), Yang Lian, the commander of Lanzhou Wei, moved the floating bridge to its present position at the foot of Baita Mountain. Up to now, there are still three cast iron floating bridge columns with a weight of 10 tons and a length of 5.8 meters, which are called "general columns". On the column, the inscription "in the ninth year of Hongwu, the age of the second Bingchen, on the auspicious day of August, the commander in chief sued the Duke of Wei to build the column in the south of the pontoon, and tied the iron cable 120 feet.".

At that time, the Yellow River floating bridge used 24 large boats to row across the Yellow River. The distance between the boats was 5 meters. The boats were connected by long wood, paved with boards and surrounded by railings. There were 4 vertical iron pillars and 45 large wooden pillars on the north and south sides of the river. There were two thick iron ropes 50 meters long each to fix the boats on the river. In winter, the Yellow River will be removed when it freezes, and in spring, the floating bridge will be built again. The poem "peach blossom and ice in March, the willows of bingpan River Bridge are green" is the portrayal of the floating bridge at that time. One of the eight ancient sceneries in Lanzhou, "dragon subduing and dragon locking" also refers to this kind of scenery.

In 1907, under the proposal of Peng Yingjia of Lanzhou road and the sponsorship of Shengyun, the governor of Gansu Province, the Qing government used 306690 taels of state treasury silver to construct the floating bridge. Under the technical guidance of man baoben, an American, and de Rohe, a German, the floating bridge was rebuilt into the first iron bridge of the Yellow River, 233.3 meters long and 7.5 meters wide, which was originally named Lanzhou Yellow River Iron Bridge. In 1942, it was rebuilt into Lanzhou Yellow River Iron Bridge "Zhongshan Bridge".

When the railway bridge was built, kayou labor protection was guaranteed for 80 years. However, it lasted only 42 years, that is, in 1949, the Tieqiao was interrupted for 11 days and nights due to the war. After rush repair, although the traffic was restored, the deck on the footbridge was unstable, which made it difficult to undertake the increasingly busy transportation task. In 1954, the people's government carried out a comprehensive renovation and reinforcement of the iron bridge, adding arc-shaped steel arch beams, making the old iron bridge not only strong and durable, but also majestic and magnificent.

With the passage of time, more than 10 railway and highway bridges with beautiful shape, novel structure, advanced technology and extraordinary momentum have been built in Lanzhou city. This ancient iron bridge of the Yellow River is no longer the only channel connecting the north and south of the Yellow River. Nevertheless, people still admire it and enjoy it, because it is like an epic, which depicts the historical changes of Lanzhou from ancient times to the present, and shows the splendid art of Lanzhou people.

The story of the Yellow River Railway Bridge in Lanzhou

Wanli Yellow River no bridge

Guangxu Cixi was ashamed

Lanzhou river is 200 meters wide

It costs less to build an iron bridge

Beijing Hanlin shakes his head

Chinese Luban can't make it

Among the several natural scenic spots related to the Yellow River in Baotou, there is only one pontoon bridge reinforced by modern people left in the ancient Yellow River Ferry. Nanhai park is full of impetuous man-made amusement projects. Only the Yellow River water under the Yellow River Bridge, though it has experienced many vicissitudes, has been flowing as always. Baotou Yellow River Bridge

The river here is not the widest section of the Yellow River Basin, and the Yellow River bridge here is not the most magnificent bridge. The reason why we recommend the Yellow River Bridge is that it is a scenic spot that few people pay attention to. In fact, the only artificial landscape facility is a sculpture under the old bridge, which is called "cradle". Few people go sightseeing at ordinary times. On the contrary, they feel at home here. Here, you can quietly watch the Yellow River shimmering in the afterglow of the setting sun. A few rowing boats are tied to the shore. Under the willow trees, the wolf dog of the fisherman looks at you curiously without barking. The cars on the bridge come and go in a hurry, but they are happy under the bridge. I think that this is the expression of the gentle motherhood of he, the mother of Chinese children. Baotou Yellow River Bridge is responsible for connecting Baotou Xi'an Highway. The new bridge is a construction project loaned by Inner Mongolia Autonomous Region to the world bank and has not yet been completed. The new bridge is 100 meters away from the old one.
