The first bridge in China is the Wuhan Yangtze River Bridge.

Wuhan Yangtze River Bridge is the first Yangtze River bridge built after the founding of the People's Republic of China, and is one of the important historical landmarks in Wuhan, Hubei Province, China.

Wuhan Yangtze River Bridge starts from Chuqin Interchange in the west, crosses the Yangtze River waterway in the east, and reaches Zhongshan Road in the east; The total length of the line is 1,670 meters, and the total length of the main bridge is 1,156 meters; The upper deck is a two-way four-lane urban arterial road with a design speed of 100 km/h, and the lower deck is a double-track track with a design speed of 160kmh.

Construction Background:

Wuhan is located in the hinterland of China, the middle reaches of the Yangtze River, from which the Han River flows into the Yangtze River, has an important geographical advantage, and was once praised by Sun Yat-sen as a large commercial port that "connects nine provinces within and connects to the ocean outside". By the end of the Qing Dynasty, Wuchang was the capital of Hubei Province, Hankou was a commercial port, and Hanyang also developed a certain industrial base.

In 1906, the Jinghan Railway was opened to traffic, and the Guangdong-Hanzhou Railway was also under construction.

According to historical records, the idea of building the first Yangtze River bridge in Wuhan was first proposed by Zhang Zhidong, the governor of Huguang, to connect the north-south railway. In May 1912, Zhan Tianyou, a Chinese railway engineer, was hired by Beiyang ** as the office of the Guangdong-Hanzhou Railway.

In the process of re-surveying and delineating the Guangdong-Hanzhou Railway, Zhan Tianyou considered that the Guangdong-Hanzhou Railway and the Jinghan Railway would cross the river in the future, so he also reserved the position of connecting with the Jinghan Railway when planning the Wuchang Railway Ranglu Station (Tongxiangmen Station).

Construction of the bridge began on June 7, 2003 and was officially opened to traffic on May 1, 2008. The land distance from Ningbo, Zhejiang to Xinzhuang, Shanghai is only 179 kilometers, which is shortened by about 120 kilometers, which also relieves the pressure of the already congested Shanghai-Hangzhou-Ningbo Expressway and forms a two-hour traffic circle of Jiangsu, Zhejiang and Shanghai with Shanghai as the center.

The overall layout of the Hong Kong-Zhuhai-Macao Bridge.

The Hong Kong-Zhuhai-Macao Bridge consists of three navigable bridges, one undersea tunnel, four artificial islands and connecting bridges and tunnels, non-navigable continuous beam bridges in deep and shallow water areas, and land links between Hong Kong, Zhuhai and Macao.

Among them, the three navigable bridges from east to west are Qingzhou Waterway Bridge, Jianghai Direct Ship Waterway Bridge and Jiuzhou Waterway Bridge; The Cross Harbour Tunnel is located between Lantau Island and the Qingzhou Channel Bridge in Hong Kong, connecting other sections of the bridge through the east-west artificial islands. The non-navigable continuous beam bridges in the deep and shallow water areas are located in the waters near Hong Kong and Zhuhai respectively. The three ports and their artificial islands are located near the approach bridges at both ends, and are connected to the surrounding major highways by connecting lines.

Wuhan Yangtze River Bridge, Hong Kong-Zhuhai-Macao Bridge ......

China's most recently completed world-class bridge is called the Hong Kong-Zhuhai-Macao Bridge.

Hong Kong-Zhuhai-Macao Bridge (English: Hong Kong-Zhuhai-Macao Bridge; Portuguese: Ponte Hong Kong-Zhuhai-Macau) is a sea-crossing bridge under construction in Hong Kong, Zhuhai and Macau, connecting Tung Chung on Lantau Island and Hong Kong International Airport, Macau Peninsula and Zhuhai City, Guangdong Province, the project started on December 15, 2009, and all sections of the road were completed in December 2017, with a design life of 120 years.

The total length of the Hong Kong-Zhuhai-Macao Bridge is nearly 50 kilometers, and the total length of the main project is about 35 kilometers, including a sea-crossing bridge, an offshore artificial island and an undersea tunnel. When completed, it will be the world's longest 6-lane immersed tunnel and the world's longest bridge-tunnel road. The completion of the Hong Kong-Zhuhai-Macao Bridge will greatly reduce the traffic time through the three places, when the three places can reach only about 1 hour of travel time, and there is no need to detour to Shenzhen and Humen, and Hong Kong, Zhuhai, Macao will also form a "1-hour living circle".

It doesn't matter how many there are, what matters is how many bridges have been in use for several years and why haven't they collapsed yet?

The longest completed bridge is the Runyang Yangtze River Bridge.

Runyang Bridge is currently the first bridge on the Yangtze River composed of two types of bridges: cable-stayed bridge and suspension bridge, which can be called the perfect combination of Jiangyin Yangtze River Bridge and Nanjing Yangtze River Second Bridge. The Nanqiao Bridge is a single-hole double-hinged steel box girder suspension bridge with a span of 1,490 meters, which is currently "the first in China and the third in the world" large-span suspension bridge.

In the past, from Yangzhou to Zhenjiang mainly through a ferry in between, the passage time took more than 20 minutes to take a ferry from Jingkou to Guazhou. The reporter drove on the Runyang Bridge for the first time, and it took less than 5 minutes to cross the river at a speed of 100 kilometers per hour. Runyang Bridge crosses the Yangtze River with two bridges, turning the moat into a thoroughfare.

It is an important project in the main framework of the "four vertical, four horizontal and four linked" highways planned by our province and five national highways across the river. The bridge is located about 2 kilometers upstream of Zhenyang Steam Ferry, with a total length of kilometers, and is a two-way six-lane bridge with a design speed of 100 kilometers per hour. It starts from Yangzhou City in the north and connects with the Beijing-Shanghai Expressway and Nanjing-Tong Expressway at the same time; It is connected to National Highway 312 in the south and Shanghai-Nanjing Expressway and Nanjing-Hangzhou Expressway.

In the past, the Zhenyang steam ferry would often be stopped due to fog and other weather, causing the convoy waiting to pass five kilometers away; Moreover, in the past, it often took nearly an hour to enter the city on the Shanghai-Nanjing Expressway after passing through the ferry, and it only took more than 20 minutes to pass through the Runyang Bridge.

The longest bridge under construction is the Hangzhou Bay Bridge.

Hangzhou Bay Bridge is currently the world's longest sea-crossing bridge, the bridge is located in China's reform and opening up of the most dynamic, the most economically developed Yangtze River Delta region, the project at the end of 2003 to start construction, is expected to be completed at the end of 2008 and opened to traffic in 2009.

The construction of Hangzhou Bay Bridge is of far-reaching strategic significance for the economic and social development of the entire Hangzhou Bay, the bridge is a convenient passage for the main trunk of the national highway and the third line to cross Hangzhou Bay, starting from Haiyan Zhengjiali in Jiaxing City in the north, crossing the wide sea area of Hangzhou Bay and ending at Cixi Waterway Bay in Ningbo City, with a total length of 36km. After the completion of the Hangzhou Bay Bridge, the land distance between Ningbo and Shanghai will be shortened by more than 120 kilometers.

The Hangzhou Bay Bridge, the longest bridge in China and the longest sea-crossing bridge in the world, was put into traffic on May 1, 2008.

The Hangzhou Bay Bridge starts from Haiyan Zhengjiadai in Jiaxing City in the north, crosses the flare-shaped Hangzhou Bay, and ends at Cixi Waterway Bay in Ningbo City, with a total length of 36 kilometers, two-way six lanes, and a design speed of 100 kilometers per hour.

In the future, the Hangzhou Bay Bridge will be replaced by the Hong Kong-Zhuhai-Macao Bridge, which is under construction.

The Hong Kong-Zhuhai-Macao Bridge is a huge bridge connecting Hong Kong, Zhuhai and Macao, and is of great strategic significance in promoting the further economic development of Hong Kong, Macao and the west bank of the Pearl River Delta.

The total length of the Hong Kong-Zhuhai-Macao Bridge is kilometers, and the main project "Bridge and Tunnel in the Sea" is kilometers long, with a design speed of 100 kilometers per hour.
