The span of the bridge is a comprehensive manifestation of the technological strength and national strength of a country's bridge. Because the suspension bridge can withstand the tensile force, it is currently the most capable bridge type.

Participants introduced in the secondary Airlines Bureau of China Central Enterprises that the bridge has six "most worlds" and six "world first". The six "most in the world" include the maximum span suspension bridge, the highest suspension bridge tower, the maximum volume of the wall anchoring foundation, the maximum high -strength main cable, the maximum continuous length steel box beam, and the maximum displacement. Six "world first" are the main cable of the ultra -large span suspension bridge main cable, ultra -high steel box -steel pipe constraint concrete combination Soka, ultra -large -scale support structure composite to the wall anchor foundation, ultra -large self -assembly cable Saddle, intelligent perception can replace the anchoring system, and the whole bridge integrated intelligent anti -corrosion system.

The bidding section of the main project of the construction bridge of the China Communications Second Aviation Bureau is located on the side of Zhangjiagang, including the main pagoda, auxiliary tower, and south anchor foundation of the main channel of the Yangtze River.

The person in charge of the enterprise said that it will ensure a magnificent leap of 2300 meters and build the bridge into a representative project led by the Chinese bridge scientific and technological innovation.

As the country's "Fourteenth Five -Year Plan" period of the river crossing project that focuses on construction, the bridge directly connects G40 Shanghai Shaanxi and G4221 Shanghai Wuwu two national high -speed road network channels to connect Suzhou, Nantong, and Taizhou City to form a regional new river highway The convenient channel for transportation is of great significance to promote the integration of the Yangtze River Delta regional and the development of the Yangtze River Economic Belt.
