Feng Maorun, chief engineer of the Ministry of Communications, said that it is a landmark building for China's transformation from a "big country in bridge construction" to a "strong country in bridge construction".

On April 28, the Sutong Bridge, with a total length of kilometers and a main span of 1088 meters, became the world's largest span cable-stayed bridge, creating four world records for cable-stayed bridges, including the deepest bridge pile foundation, the highest cable tower, the largest span and the longest cable-stayed cable, and its majestic posture became a beautiful scenery across the Yangtze River.

The Sutong Bridge, which is under construction, is located between Nantong City and Suzhou (Changshu) City in the eastern part of Jiangsu Province, and is an important passage across the Yangtze River on the national key trunk highway from Jiayin in Heilongjiang Province to Nanping in Fujian Province planned by the Ministry of Communications. With a total investment of 100 million yuan, the Sutong Bridge has a total length of kilometers, and the main hole span of the cable-stayed bridge is 1,088 meters, ranking first in the world; The height of the main tower is 306 meters, ranking first in the world; The length of the cable-stayed cable is 580 meters, ranking first in the world. The steel strength level of the cable-stayed cable of Sutong Bridge is 1770 megapascals, and the longest single cable is 577 meters, and its technical indicators have reached the world's advanced level.

The total length of the Sutong Bridge is 32,400 meters.

Sutong Yangtze River Highway Bridge is referred to as the Sutong Bridge, located in Jiangsu Province, China, is an important hub of the national high-speed Shenyang Haikou Expressway (G15) across the Yangtze River, and is also an important part of the main skeleton network of Jiangsu Province highway "Longitudinal One" - Ganyu to Wujiang Expressway, which is the largest project in the history of bridge construction in China at that time, and the most complex construction conditions of the extra-large bridge project. The construction of Sutong Bridge started in June 2003, the main bridge was closed in June 2007, and was completed and opened to traffic on June 30, 2008.

Sutong Yangtze River Highway Bridge north from the Tongqi Expressway Xiaohai Interchange, across the Yangtze River waterway, south to the Sujiahang Expressway Dongbang Interchange, a total length of kilometers, of which the cross-river part is 8146 meters long, the bridge deck is a two-way six-lane expressway, the design speed of 100 kilometers per hour.

From 0:00 on August 15, 2022 to 24:00 on September 8, 2022, the G15 Shenhai Expressway Sutong Bridge section (from north to south) will implement closed centralized maintenance construction. At more than 9 o'clock in the evening of the 28th, after about 13 hours of intense construction, the epoxy asphalt paving of the steel deck of the main bridge of Sutong Bridge was successfully completed.

Operation of Sutong Bridge:

Sutong Yangtze River Highway Bridge is incorporated into the Jiangsu Provincial Expressway Network Toll System for network toll collection, of which, 7 or less cars through the cross-river bridge toll 30 yuan, trucks to implement weight charging. Sutong Yangtze River Highway Bridge is divided into three parts: the north and south banks of the highway and the cross-river bridge, and the collection of vehicle tolls is also "the bridge to the bridge, the road to the road", among them, the vehicle toll of the north and south bank connection is calculated according to the mileage and vehicle type, and the toll of the cross-river bridge is calculated according to the number of vehicles and models.

There are a total of 5 toll stations on the whole line of Sutong Yangtze River Highway Bridge, namely 2 main line toll stations in the south of Sutong Yangtze River Highway Bridge and north of Sutong Yangtze River Highway Bridge, and 3 ramp toll stations in Changshu Kaimo Enlightenment Zone, Nantong Development Zone and Zhuhang.

<>1. The western section of Sutong Bridge is about 6km wide near Tianshenggang, and it is widened downward, about 10km wide near Junshan, and 14km wide at the corner of Dongfanghong Farm, and then it is suddenly narrowed down to about 6km wide near the section of the Xuliujing node where the eastern section of the bridge is located. The north bank of Sutong Bridge is connected to Yantong Expressway, Ningtong Expressway and Tongqi Expressway, and the south bank is connected to Sujiahang Expressway and Yanjiang Expressway.

2. Sutong Bridge across Nantong and Changshu, Suzhou, 82 kilometers away from Jiangyin Bridge in the west and 108 kilometers away from the Yangtze River estuary in the east. The total length of the project is kilometers, and it is composed of three parts: the cross-river bridge project and the north and south bank connection project. Among them, the cross-river bridge composed of the main bridge, the special channel and the north-south approach bridge is about 8,200 meters long, after completion, it will become the first bridge of the Yangtze River, and at the same time will create four new records in the history of bridge construction in the world.

The main span of the bridge is 1,088 meters, ranking first in the world. Sutong Bridge will go down in history as the world's largest cable-stayed bridge in the world. Therefore, Feng Maorun, chief engineer of the Ministry of Communications, said that the Sutong Bridge is a landmark building for China's transformation from a "big country in bridge construction" to a "strong country in bridge construction".

The Sutong Bridge will create four world firsts.

On the mighty Yangtze River, the Sutong Bridge, which connects the two ancient cities of Suzhou and Nantong, is showing its majesty. This kilometer-long bridge is the world's largest bridge under construction.

According to He Ping, deputy commander of the construction of the Sutong Bridge, the Sutong Bridge is composed of three parts: the cross-river bridge project and the south and north bank connection projects. The whole line adopts the standard of two-way six-lane expressway. The total investment of the bridge is about 6.45 billion yuan and is expected to be completed by the end of 2008.

The construction process of the Sutong Bridge will overcome a series of global problems and create four world bests.

Bridge construction project: Sutong Bridge project starts from the Xiaohai interchange of Tongqi Expressway, and finally ends at the Dongbang interchange of Sujiahang Expressway. The total length of the route is kilometers, and it is mainly composed of three parts: the north bank connection project, the cross-river bridge project and the south bank connection project.

l. Cross-river bridge project: the total length is 8206 meters, of which the main bridge adopts 100 + 100 + 300 + 1088 + 300 + 100 + 100

2088 meters of twin-tower double-cable-surface steel box girder cable-stayed bridge. The main hole span of the cable-stayed bridge is 1088 meters, ranking first in the world; The height of the main tower is 306 meters, ranking first in the world; The length of the cable-stayed cable is 580 meters, ranking first in the world. The plane size of the pile foundation is m x m, ranking first in the world. The special waterway bridge adopts a T-shaped rigid beam bridge of 140 + 268 + 140 = 548 meters, which is the second in the world for similar bridge projects; The north-south approach bridge adopts a meter prestressed concrete continuous beam bridge;

2. North bank wiring project: the total length of the route is 15 1 kilometers, with two interchanges, one main line toll station and one service area;

3. South bank wiring project: the total length of the route is 9 1 kilometers, and there is an interchange.

Sutong Bridge adopts two-way six-lane highway standard on the whole line, calculates the speed of the south and north banks of the connection for 120 kilometers and hours, cross-river bridge is 100 kilometers and hours, and the design load of the whole line bridge and culvert adopts a car over 20 levels, and a trailer is 120. The navigable clearance of the main bridge is 62 meters high and 891 meters wide, which can meet the navigation needs of 50,000-ton container ships and 10,000-ton fleet. The whole line needs a total of about 250,000 tons of steel, 1.4 million square meters of concrete, 3.2 million square meters of filling, more than 10,000 acres of land, and 260,000 square meters of demolished buildings.

The total investment of the project is about 100 million yuan, and the planned construction period is six years.

The largest main span: Sutong Bridge has a span of 1088 meters, which is the largest cable-stayed bridge in the world today.
