The world's first cable-stayed bridge with a span of over one thousand meters was completed and opened to traffic

On July 1, the Shanghai-Tong Yangtze River Highway and Railway Bridge with a main span of 1092 meters was completed and opened to traffic. This is the world's first road-rail dual-use cable-stayed bridge with a span of more than one kilometer, marking that the world's road-rail dual-use cable-stayed bridge will enter the "thousand-meter" era.

In addition, the Shanghai-Tong Yangtze River Highway-Rail Bridge has also created many world-classes: the main tower is 325 meters high and about 100 stories high. It is the world's tallest road-rail dual-use cable-stayed bridge; the amount of steel used is up to 48. 10,000 tons, equivalent to the steel used in 12 "Bird’s Nests", the largest bridge construction in the world; 500MPa high-strength steel was used for the first time. It is understood that 500MPa high-strength steel means that the maximum weight that a steel beam can withstand per square meter is 5,000 tons. It is equivalent to the weight of 2500 cars; it can withstand the damage of a magnitude 14 typhoon, a magnitude 8 earthquake and the impact of a 100,000-ton ship. The successful completion of the Shanghai-Tong Yangtze River Highway and Railway Bridge is inseparable from the assistance of many steel companies. In order to achieve the span of the bridge over one kilometer, the technical indicators proposed by the bridge construction party for the steel grade Q500qE used in the bridge are all higher than the bridge steel standards of all countries in the world, and the requirements for strength are also very high.
