On December 29, 1968, more than 50,000 military and civilians in Nanjing gathered at the bridgehead by the river and held a grand meeting to celebrate the full completion of Nanjing Yangtze River Bridge . After the celebration, the red signal flares rose into the air. Amid the sound of firecrackers and gongs, more than 100 floats , filled with representatives of Nanjing people, slowly passed through the road bridge. Suddenly, there was a lot of joy in the north and south of the river, on and under the bridge, inside and outside the car, and cheers shocked the earth and resounded throughout the sky.
Nanjing is located in the lower reaches of Yangtze River and is a key transportation hub in East China. Building an Yangtze River Bridge here is a long-standing wish of the Chinese people. However, the river is wide and the water is urgent here, and the engineering geological conditions are complex. In 1927, an American bridge expert came to Nanjing for on-site inspection and left a sentence: It is impossible to build a bridge in Nanjing. However, it is in this "impossible" place that a bridge built with special steel developed by our country was completed and opened to traffic in the 19th year after the founding of New China in .

The construction of the bridge took 10 years. In November 1958, the Nanjing Yangtze River Bridge Construction Committee was established. In January 1960, the main project of the bridge, Jiangxin Bridge Pier, was officially started. Engineering and technicians dived more than 60 meters underwater to perform underwater welding and underwater cutting. By April 1966, all nine piers in the river had been built on the water. Song Peiqi, the construction team leader of that year, said: "Many people may not know the hard work of bridge workers. In winter, on the empty river surface, the wind is cold, and the steel can stick a layer of skin when touching the steel. At the end of the day, your fingers often cannot stretch. In summer, the coagulation workers still have to be stuck in the middle of tight model boards and steel plates every day, working for seven or eight hours, the inside of the template is not ventilated, and the temperature is 10 degrees Celsius higher than the outside. At the end of the day, a thick layer of salt frost formed on their clothes..." The bridge builders carried forward the spirit of thrift, and the marking workers "tailored" to save steel; the steel bar workers were careful to calculate and did not waste a steel bar; the welders were reluctant to throw away the remaining one-inch-long weld head.

Through the joint efforts of builders and the people of Nanjing, on September 30, 1968, the Nanjing Yangtze River Bridge Railway Bridge was completed and opened to traffic. On December 29 of the same year, the highway bridge was completed and opened to traffic.
Nanjing Yangtze River Bridge highway bridge is 4588 meters long and the railway bridge is 6772 meters long. It was the largest railway and highway dual-purpose bridge with the most complex bridge technology in China at that time. During the bridge construction process, a large number of new processes and new technologies created by engineering and technical personnel reached the advanced level of the world at that time. For example: After research, the Bridge Engineering Bureau adopted four foundation forms: heavy concrete caisson, steel sheet pile cofferdam pipe column, steel caisson plus pipe column, floating reinforced concrete caisson, and 9 bridge piers were firmly fixed on the rock formation at the bottom of the river. On May 15, 1986, the new technology for building a bridge in the Nanjing Yangtze River Bridge won the National Science and Technology Progress Award.
