Runyang Yangtze River Highway Bridge

Runyang Yangtze River Highway Bridge, referred to as Runyang Bridge, is a bridge project connecting Zhenjiang City and Yangzhou City in Jiangsu Province of China. It is an important part of the main framework and the Yangtze River Crossing channel planning of the "four vertical, four horizontal and four connected" expressway network in Jiangsu Province.

Runyang Yangtze River Highway Bridge started construction on October 20, 2000;

It was put into operation on June 1, 2004;

The main project was basically completed on February 2, 2005;

It was officially opened to traffic on April 30, 2005.

Runyang Yangtze River Highway Bridge starts from Yangzhou South Ring Road in the north, crosses Shiyezhou in the Yangtze River, and ends at Zhenjiang 312 National Highway Interchange in the south, with a total length of 35.66 km. The bridge deck is a two-way six lane Expressway with a design speed of 100 km / h. The total investment of the project is 5.81 billion yuan.

Construction process

After investigating the situation around Zhenjiang and Yangzhou ferry, Wang Zhong, a Yangzhou scholar in the Qing Dynasty, wrote a proposal on building a floating bridge at Jingkou, which proposed the idea of building a floating bridge between Guazhou Jinshan Zhenjiang, and became the initiator of building Runyang Yangtze River Bridge.

In 1919, Dr. Sun Yat Sen, the great pioneer of China's democratic revolution, planned two Yangtze River bridges in his book industrial plan. One is the Wuhan Yangtze River Bridge in the middle reaches, and the other is the Zhenjiang Yangzhou Yangtze River Bridge in the lower reaches. This is the first person who proposed to build a modern Yangtze River bridge between Zhenjiang and Yangzhou.

Bridge structure

Runyang Yangtze River Highway Bridge is a combined bridge including two long-span cable bridges and their approach bridges. The whole bridge is composed of North connection, North Branch bridge, Shiyezhou interchange viaduct, South Branch bridge, South connection and extension section. The main bridge of South Branch is single span double hinged steel box girder suspension bridge, and the North Branch is three span double tower double cable plane steel box girder cable-stayed bridge.

From the appearance, the main cable of the South Branch suspension bridge of Runyang Yangtze River Highway Bridge is curved, like a graceful girl, while the cable of the North Branch cable-stayed bridge is tight, like a strong young man.

Design parameters

As of April 2005, Runyang Yangtze River Highway Bridge is about 60 km away from Nanjing Second Bridge in the West and 110 km away from Jiangyin Bridge in the East, with a total length of 35.66 km. The main bridge (including Beicha bridge, Shiyezhou interchange viaduct and Nancha bridge) is 7.21 km long, the North approach bridge and North connection viaduct are 1.74 km long, the North connection is 10.27 km long, and the South connection and extension are 16.44 km long.

As of September 2009, the main bridge of South Branch of Runyang Yangtze River Highway Bridge is a single span double hinged steel box girder suspension bridge with a main span of 1490m and a main tower height of 215.58m,

When completed, its span ranks first in China and third in the world; Beicha bridge adopts 176m + 406m + 176m three span double pylon double cable plane steel box girder cable-stayed bridge, and approach bridges adopt prestressed concrete continuous box girder bridge; the design service life of Runyang Yangtze River Highway Bridge is 100 years. At the site of Runyang Yangtze River Highway Bridge, the Yangtze River is divided into two branches by Shiyezhou: the South Branch is the main stream of the Yangtze River, mainly passing through sea vessels and fleets; the North Branch is a tributary, mainly sailing ships of less than 200 tons. Runyang Yangtze River Highway Bridge is a highway standard. From Yangzhou South Ring Road to Zhenjiang 312 National Road, it is a two-way six lane bridge with a design speed of 100 km / h. from Zhenjiang 312 National Road to Dantu hub, it is a two-way four lane bridge with a design speed of 120 km / h. It can withstand the earthquake intensity of 7 degrees. The full width of the bridge deck is 32.5 meters. The net height of the South Branch is 50 meters for the sea liner and 24 meters for the river liner It is 390 meters for seagoing vessels and 700 meters for river vessels. The North Branch is navigable with a clear height of 18 meters and a clear width of 210 meters.

Operation

Ticket price

In April 2005, at the initial stage of the completion of Runyang Yangtze River Highway Bridge, the toll is divided into two parts: the toll of cross river bridge and the toll of Expressway in connection and extension section. The charging method is to charge the passenger cars according to the model, the freight cars according to the weight, and the whole weight charging system according to the model in case of failure. Among them, the vehicle toll of the river crossing bridge is 20 yuan / vehicle for the whole bridge of 7-seat passenger cars or less.
