Nanjing Yangtze River Bridge officially started in June 1960 65438+ 10/8. The railway bridge opened to traffic in September, 1968, and the highway bridge opened to traffic in February of the same year, 65438. Nanjing Yangtze River Bridge is a super-large bridge with both railway and highway functions. The railway bridge is 6772 meters long, and the highway bridge is 4588 meters long. Ten thousand-ton ships can pass under it. Nanjing Yangtze River Bridge is the third largest bridge across the Yangtze River after Wuhan Yangtze River Bridge and Chongqing Baishatuo Yangtze River Bridge. After the bridge was opened to traffic, the two lines of Jinpu and Shanghai-Nanjing were formally connected, and they could go directly from Beijing to Shanghai. Since then, beijing-shanghai railway has been fully integrated. Nanjing Yangtze River Bridge consists of an approach bridge and a main bridge. The upper floor is a highway bridge. The length of the main bridge is1577m, the length of the approach bridge is 3012m and the width is19.5m, which can accommodate four large trucks in parallel at the same time. The lower floor is a railway bridge with a total length of 6772m and a width of14m. Double track laying, two trains can leave at the same time. There are 22 bridge holes with distinctive national characteristics in the grounding parts at both ends. There are a pair of bridge heads in the north and south of the bridge, which are 70 meters high. There are three red flags on each bridgehead, symbolizing the people's commune, the Great Leap Forward and the general line of the 1950s. The five figures on the statue were the five major components of China society at that time, namely, industry, agriculture, soldiers, learning and business. They hold high the five-star red flag and hold their heads high, symbolizing the spirit of hard struggle of unity and revolution. 150 pairs of magnolia lanterns are arranged neatly on both sides of the bridge. When night falls, all the lanterns are in full bloom and thousands of lanterns are lit, which makes the magnificent appearance of the bridge clearer and more charming. It's really a picture of "suspecting that the Milky Way has fallen for nine days". As one of the 40 scenic spots in Jinling, "Flying Rainbow" is worthy of its name. Although the Yangtze River, known as the "golden waterway", has made great contributions to the inland navigation in China, it has also caused the situation that residents on both sides of the strait can not conduct economic and cultural exchanges for a long time. Nanjing Yangtze River generally refers to the river surface from anhui cuisine market to Zhenjiang, Jiangsu. The ground here looks like a Chinese-style chest covering, and the water depth is steep. The average width of the river channel exceeds 1500m, and the narrowest part is also 1 100m. The water depth is mostly 15 ~ 30m, the deepest part is over 70m, and the velocity is 3m/ s. The dangerous terrain has formed the "natural graben of the Yangtze River". The natural barrier of the Yangtze River has always been a battleground for military strategists. According to historical records, as early as 202 BC, Xiang Yu, the overlord of Chu, was trapped by Liu Bang and broke through to the south, but he could not cross the river and turned to attack Jiangxi. He had no choice but to draw his sword and commit suicide in wujiang town. Up to now, dachang town in the north of Qiaobei still retains the names of Xiejiadian and Wang Ba Mountain. The Kuomintang, headed by Chiang Kai-shek, still fantasized about continuing to fight the natural barrier of the Yangtze River, but the heroic People's Liberation Army crossed the river with the momentum of a million heroes on April 23, 1949, and liberated Nanjing.
