Saihong Bridge

Saihong Bridge

Saihong bridge, located in the southwest of Nanjing Jiqingmen, north of Saihong Bridge Interchange, crosses the tributary of Qinhuai River. Built in the Hongwu Period of the Ming Dynasty, it is a three arch stone bridge, once known as Saigong bridge and Saigong bridge. The outside of the bridge is facing the tamxiang gate of Waiguo city of the Ming Dynasty. Shiqiao is now a cultural relic protection unit in Nanjing.

It is said that Zhu Yuanzhang, the emperor of Ming Dynasty, built the capital, which was undertaken by the Ministry of industry and yingtianfu. The construction of Tianfu city has been completed, and there is still more capital, so a stone bridge was built here, which is called Saigong bridge, meaning to surpass the Ministry of industry. Later, in order to avoid "slight insults on the stage", the local officials changed their name to Saihong bridge by taking the meaning of "long bridge lies on the waves, no clouds and no dragons; the road is empty, no Ji and no rainbow" in a Fang Gong Fu by Du Mu of Tang Dynasty. It is also called Saigong bridge and zhahong bridge.

Saihongqiao was rebuilt during the reign of Emperor Kangxi of Qing Dynasty. The width of the bridge is more than 50 meters, the length of the diversion pier is more than 60 meters, and the height of the arch is 8.95 meters. So far, it can still carry 8 tons. Its width is rare in the history of Nanjing ancient bridge. In 1947, "Saihong bridge defense war memorial tower" was built beside the bridge.

Saihongqiao interchange was built in 2003. It is called saihongqiao interchange because it is close to saihongqiao. Saihongqiao interchange starts from Shuiximen viaduct in the north, connects Fengtai South Road in the south, Zhongshan South Road in the East and Yingtian West Road in the west, including Fengtai Road widening, Fengtai Road Shunhe bridge and Jiqingmen tunnel.

Saihongqiao interchange is not only the largest two-way interchange in Nanjing city construction history, but also the largest city in China. The total investment of the project is 1.2 billion yuan, with a total area of 132600 square meters. The total length of the bridge is 10 kilometers, which is 39 meters wide, two-way and six lane asphalt road. There are 486 single bridge piles. The interchange is divided into four floors from the top to the ground, 23 meters high and 8 floors high.

geographical position

Saihong bridge is located on Changhong Road, southwest of Jiqingmen, south of Nanjing city. It crosses the tributary of Qinhuai River and was built in Hongwu Period of Ming Dynasty. It was once known as Saigong bridge and Saigong bridge.

Saihong bridge was built in Hongwu Period of Ming Dynasty, facing the tamxiang gate of Nanjing city at that time. It is a three arch big stone bridge, which was rebuilt in Kangxi period of Qing Dynasty. The width of the bridge is more than 50 meters, the length of the diversion pier is more than 60 meters, and the height of the arch is 8.95 meters. So far, it can still carry 8 tons. Its width is rare in the history of Nanjing ancient bridge.

The name of Saigong bridge comes from some legends and notes when Zhu Yuanzhang built the southern capital. At the end of the Ming Dynasty, Zhu Guozhen wrote in his Yongchuang sketch: when Emperor Taizu built the outer city of Nanjing, he asked the Ministry of work and yingtianfu to take charge of it by sections. Ying Tianfu is responsible for the eight gates from the tame elephant gate. As a result of careful organization, they not only completed the task with quality and quantity in advance, but also saved the special funds for building the city. If we can calculate the time, we can also build a bridge before the completion of the section under the responsibility of the Ministry of industry. So decided to use the balance to build the bridge, this bridge is Saigong bridge. The purpose of yingtianfu bridge was to show off before emperor Taizu of the Ming Dynasty: our local government dares to compete with the Ministry of industry, a large part of the central government. It is said that for this matter, Emperor Taizu of the Ming Dynasty severely reprimanded the officials of the Ministry of work. As soon as Ying Tianfu heard the training from the Ministry of industry, he knew that he had committed the crime of "slight humiliation on coming to power". He rushed to the Ministry of industry to make an apology, and quoted Tang Dumu's "a Fang Gong Fu" as saying, "long bridge lies in waves, what is the cloud? In the sentence of "no Ji He Hong", Saigong bridge was renamed as "Saihong bridge".

legend

In the eyes of the common people, Saihong bridge has always been read as "Saigong bridge", because the legend of Saigong bridge is more popular among the common people.

According to legend, the bridge was built by the daughter-in-law of Shen Wansan, a wealthy man in the south of the Yangtze River. When the southern capital was built, due to the state's initial creation and the empty state treasury, Zhu Yuanzhang knew that he could not complete such a huge project by relying on the state's financial resources. As a result, rich households in the south of the Yangtze River were forced to "pledge" the cost of building Nanjing city.

Shen Wansan was a very rich businessman. In order to please emperor Taizu of Ming Dynasty, he pledged one third of the cost of building the city. Later, he donated half of the cost of building the capital Waiguo. As soon as the city was half built, Shen Wansan was at ease. He didn't pay attention to some auxiliary buildings, such as the bridges on the outer moat. As soon as his daughter-in-law saw it going on like this, it had to be a big deal, because Shen Wansan and Ming Taizu had made a "gambling agreement", and they would be beheaded if they were delayed. Shen Wansan is stubborn and never listens to the younger generation's advice. His daughter-in-law is a smart man. In order to warn his father-in-law about the quality of bridge construction and prevent officials from finding fault in the acceptance, he took drastic measures and proposed "gambling game" with his father-in-law to build the bridge. So she took out her private money and built the bridge day and night. She built the bridge before the completion date Shen Wansan promised, and the quality was better than that of the bridge built by her father-in-law. So people call it Saigong bridge.

At the end of Ming Dynasty, Yang Longyou, a famous patriotic scholar in Guiyang, lived near Saihong bridge. Yang Wencong, born in Guiyang, was named Longyou in the 47th year of Wanli. He was a scholar and a civil and military man. He always had the ambition of stabilizing the country. He made close friends with Hou Chaozong (Hou Fangyu), a famous figure in the restoration society, and protected many Donglin Party members by taking advantage of his fellow townsman and affinity with Ma Shiying. When the Qing army went south, he took part in serving Emperor Li Longwu in Fuzhou, and led the lonely army to guard xianxialing with the right servant of the Ministry of war. He defeated the Qing army many times. Later, Yang Longyou was captured and died because of the difficulty of supporting the lonely army. Thirty six members of the family died at the same time. Yang Longyou is good at both literature and martial arts, especially painting. In Peach Blossom Fan, there is a story about Li Xiangjun's blood splashing fan, which Yang Longyou used to dye into a branch of peach blossom.

Saihongqiao interchange

summary

Saihongqiao interchange is the first directional full interchange in Nanjing, with two-way eight lane, four floors up and down. There are 23 main line and ramp bridges, which are diamond shaped in the air. The total length of the bridge is 16.1km, and all of them are 52 to 66m wide urban expressways. At any intersection, there are three straight, right-hand and left turn channels leading to the other three directions at the same time, and there will be no intersection and traffic jam Retrograde, up to 80 km / h. The clear height of the highest point of saihongqiao interchange is 23m, and it is 8 stories high. The Jiqingmen tunnel, which goes down to the north, is sandwiched between the Ming city wall and the outer Qinhuai River. The longest span of the river crossing bridge to the west is 70m, and the city wall, viaduct, river and tunnel are scattered, making the former dirty saihongqiao become the highlight area of Nanjing urban construction.

Saihongqiao interchange is not only the largest two-way interchange in the history of Nanjing urban construction, but also the largest city in China. The total investment of the project is 1.2 billion yuan, with a total area of 132600 square meters. The total length of the bridge is 10 kilometers. It is a 39 meter wide two-way six lane asphalt road. There are 486 single bridge piles. The interchange is divided into four floors from the top to the ground, 23 meters high and eight stories high.

effect

Saihongqiao interchange hub is the throat of the main frame of the "two ring and eight shoot" road in Nanjing, and the important contact point of the "well" shaped fast inner ring. It plays a very important role in improving the layout of trunk road network, promoting the construction and development of Hexi and south area of the city, providing smooth fast passage for the "10th National Games", opening up the weiqi road cross river passage, and speeding up the construction of a modern riverside city . The main city of Saihong bridge is connected with the inner ring expressway of Nanjing, which is connected with shuangmenqiao, Xinzhuang and Weisan Road Interchange in the planning. Weisan Road, Weiqi Road, West Main Road and east main road are built to form a fast inner ring, effectively guiding and diverting the increasingly tense urban motor vehicle traffic. The outer ring of the city is connected with Fengtai South Road and Yingtian West Road to connect Hexi and Chengdu South Anhui. Jiqing Road, Shengzhou Road, Zhongshan South Road and other main roads in the south of the city can be quickly connected to the elevated inner ring. The original half-hour time out of the city will be shortened in more than ten minutes, greatly alleviating the poor traffic situation in the south of the city.

Saihongqiao interchange, which is designed with four story "vase pier", has set many records of urban interchange in China. Shuangqiaomen interchange is larger in scale, higher in height and longer in span. It has five stories up and down, with a clear height of 32 meters and a total length of 15 kilometers. Not long after taking the bus from Zhongshan East Road to Longpan Middle Road, you can see Shuangqiaomen interchange flying across the ancient city wall and the south end of Qinhuai River, opening the "big mouth" to deal with the rolling traffic of the east main road. Climbing up the main span of Shuangqiaomen interchange from the "Zhi" shaped vertical support, with mountains and rivers far away, walls and rivers high, you can have a panoramic view of the city, and set off with the modern elevated interchange, which is another excellent place for Nanjing to overlook the style of the ancient capital. Weiqi Road, 3 kilometers long, flies through the Ming city wall, Yuhuatai and Qinhuai River, like a light ribbon tying up two colorful flower baskets.

Zou Rui, deputy general manager of Nanjing urban construction project management company, said that saihongqiao Weiqi road Shuangqiaomen overpass viaduct starts from the west main road in the west, passes through Daming Road all the way, crosses Yuhua overpass, Zhonghua Road, five east main roads in the city, and crosses Nanjing Wuhu Railway four times and one time. Nanjing Wuhu railway was not only "contracted" in the middle of the east section of weiqi Road, but also "transferred" for construction, giving way to 28 meters. The elevated overpass is like a big neck to the south of the city with complex road network. The total investment of the project is 2.5 billion yuan. The bridge is 25 kilometers long and covers an area of more than 300000 square meters. No matter in height, span and scale, it is the largest overpass construction in China. In addition to the West extension of weiqi road in the follow-up construction of saihongqiao interchange, the total investment has exceeded 3 billion yuan, equivalent to the construction of a new Nanjing Yangtze River Bridge II.

Sister bridge with different styles

Saihong bridge and Shuangqiaomen are all directional, all interchange and all interchange hubs. They are all composed of 12 express corridors. However, one is four storey, one is five storey, one is crisscross from top to bottom, which makes people "dazzled". One is "in line with the rules", horizontal and vertical. What's the reason for this design? Designer: Chief Engineer of the second exploration and Design Institute of the Ministry of Railways
