Urban environment is an embodiment of the charisma and image of a city.

Shanghai Yangtze River Bridge crosses Changxing Island at ground level and Chongming Island, ending at Chenjia Town. It consists of two long viaducts with the total length of 10.33 miles, of which 4.13 miles is road and 6.20 miles is bridge. The bridge has three road lanes in each direction, optimally designed for an average speed of 62 mph. The central cable-stayed span is about 2,395 feet long, the longest of any bridge in Shanghai, and the fifth longest in the world. The bridge is also famous for the characteristics of its combination of both highway transportation and rail transportation.


Design Concept
The design team has formed the concept of sustainability, and set the goal to build the project into a bridge that is durable, maintainable, economical and advanced with a combination of practical value and aesthetic value. Based on this concept, the design team has taken into account the characteristics of the geological condition and the requirement to maintain Chongming Island as an ecological island, and therefore has carried out various researches regarding more than 13 relevant technologies and achieved technical breakthroughs in six major aspects — including but not limited to precautions against natural calamities, combination of highway transportation and rail transportation, etc.


The Herringbone-Shaped Main Tower – Perfect Combination of Strength and Grace
Through aggressive R&D, the design team has finally settled on a herringbone-shaped tower with a 695 ft in height. The herringbone shape of the tower demonstrates Chinese traditional culture of a symbiotic equilibrium between human being and nature. The bridge deck runs through the middle of the tower and the succinct design reflects the perfect combination of strength and grace. The overall sigmoid (“S” shaped) shape of the bridge is appealing and graceful, while at the same time eliminates the adverse effect of the water current and realizes environmental sustainability.

In order to outline the shape of the bridge, blue LED light is used on the east part of the bridge which faces the East China sea and yellow LED light is used on the west part which faces Yangtze River, thus expressing the idea that Yangtze River Bridge serves as the boundary of the river and the sea. By projecting LED cold light source, the entire herringbone main tower is placed in a ray of bright light, which differentiates the 695 ft tall tower from other structures.


Project Highlights

The central cable-stayed span is about 2,395 feet long, the longest of any bridge in Shanghai, and the fifth longest in the world.

There have been 1038 fog lights installed on the bridge, which enables visibility in poor weather conditions. LED light is used as the light source for the fog lights, which realizes the role of energy sustainability.

The self-developed anti-collision technology has been used on the construction of the guardrails and has the effect of not only resisting the collision of the vehicles, but also providing buffering to protect drivers and passengers in the vehicles.

Located at the mouth of the Yangtze River, where seawater and fresh water interact, the bridge faces the constant threat of corrosion. To resolve this issue, engineers utilized advanced technology and applied fluorocarbon paint on the railings.


The Impact of the Project
Due to the special location, Chongming Island is regarded as the entrance of Yangtze River, and is also the third largest island in China. For more than 1,300 years, water transportation was the only way to the outside world, which is often affected by rainy and foggy weather, thus substantially restricting the development of Chongming Island. The completion of Yangtze River Bridge provides land transportation, making the commute from Chongming Island to the city center in 45 minutes a reality.
