Nanjing Yangtze River Bridge.

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".

The explanatory text describing the bridge is as follows:

Today's weather is so sunny, the sky is extremely bright blue, only a few tulle like light clouds, just like a girl, wearing a flower dress, how beautiful!

My dad and I went to the Shahe embankment, stood in Laohutou Park and looked west, the majestic and magnificent Rainbow Bridge spanned both sides of the Shahe River, the bridge has three large arches, and there are two piers below.

The majestic image of the bridge is reflected on the turquoise water, and the willows, grasses, and flowers form a beautiful picture. Walking on the bridge, you can see that there are two statues at each end of each large arch, and there are a total of 12 statues, the most striking of which are "Youth Melody", "Pioneering and Enterprising" and so on.

There are sidewalks on both sides of the bridge deck, and motorized lanes in the middle, where pedestrians and vehicles come and go. At night, the thousands of colored lights of the Rainbow Bridge are lit up, which is really colorful, colorful and dazzling, just like a rainbow in the night sky.

The Rainbow Bridge shows the wisdom and talent of the people of Luohe, and is the pride of the people of Luohe.

The weather was so cool that my grandparents and I went to play at the Tuosan Bridge, which was repaired in November last year. Tuosan Bridge, as the name suggests, it is the third bridge in the Jianyang section of the Tuojiang River, and the Tuo Fourth Bridge and Tuo Fifth Bridge will be repaired in the future. The bridge is 2 kilometers long and 36 meters wide.

It looks magnificent and wonderful (compared to other bridges in Jianyang).

The bridge is gray with blue railings on both sides. Standing on this side of the bridge, looking from afar, there are several buildings on the other side of the bridge, among which the red and white is the residential campus of Jianyang Middle School (I heard that it is very good), and there are several high-level residential areas, and a lot of land is still waiting to be developed.

There are signs like 40km and 2m above the bridge; 40km means that the maximum speed of the vehicle is not more than 40km per hour, and 2m means that the maximum speed of the vehicle is not more than 2m. It makes people feel safe.

I looked at the bridge, and on both sides of the bridge were the "street yard slag road" where people walked, and in the middle was the "main street" through which vehicles passed. People are talking and laughing, the vehicles are running in an orderly manner, the river on the bridge is endless, and the overpass in Chengdu is not inferior to the overpass.
