The Yangtze River is connected to the north and south, and the distant water floats through the ancient and modern. In December 1968, the Nanjing Yangtze River Bridge, the first double-decker railway and highway dual-purpose bridge designed and built by China on the Yangtze River, was fully completed and opened to traffic, and was listed in the "Guinness Book of World Records" as "the longest road-rail dual-purpose bridge".

The Nanjing Yangtze River Bridge is located in the lower reaches of the Yangtze River. The highway bridge is 4,588 meters long, with a 15-meter-wide carriageway that can accommodate four large cars in parallel, and sidewalks more than 2 meters wide on both sides. The railway bridge on the lower level is 6,772 meters long and 14 meters wide, paved with double tracks, allowing two trains to cross at the same time. The main bridge is 1577 meters long, which is the largest bridge in China.

The railings on both sides of the main bridge are embedded with 200 cast-iron reliefs. There are two bridgeheads of 70 meters high at the north and south ends, there is an elevator in the fort, and there is a sculpture of workers, peasants and soldiers with a height of more than 10 meters in front of the fort.

Nanjing Yangtze River Bridge Jiangzhong Bridge has a total of 9 piers and 10 holes, each pier is 80 meters high, and the bottom area is more than 400 square meters, which is larger than a basketball court. A 10,000-ton giant ship can be used under the bridge. Nine of the 10-hole reinforced beams of the main bridge have a span of 160 meters, which is spectacular.

The whole bridge is like a rainbow on the river, and the approach bridge part of the highway on both sides of the strait is composed of 22 double-curved arch bridges, like a beautiful color exercise, which makes the magnificent Nanjing Yangtze River Bridge appear more gorgeous and colorful. In the early morning, the red sun reflected the huge body of the bridge, like a steel rainbow lying in the sky. At night, the magnolia lanterns on the bridge are bright, like the Milky Way falling on the wide river, "It is suspected that the Milky Way falls for nine days".

The majestic Nanjing Yangtze River Bridge now has an average daily traffic flow of about 10,000-10,000. "A bridge flies north and south, and the moat becomes a thoroughfare".
