Bridge structure

The Sutong Yangtze River Highway Bridge is composed of three parts: the north bank connection project, the cross-river bridge project and the south bank connection project.

  1. Cross-river bridge project: The cross-river bridge is a steel box girder cable-stayed bridge with double towers and double cables. The dedicated channel bridge is a T-shaped rigid frame beam bridge; the north-south approach bridge adopts a prestressed concrete continuous beam bridge.
  2. The North Shore Connection Project has two interchanges, one for the main line toll station and one service area.
  3. There is an interchange in the South Bank Connection Project.

Design Parameters

The total length of the bridge is 20.1 mi (32.4 km), of which the length across the river is 5.1 mi (8.2 km). The main bridge adopts (100+100+300+1088+300+100+100) m span layout. The total length of the North Shore Connection Project is 15.1 km, and the total length of the South Shore Connection Project is 9.1 km.

The bridge body (tower) is 1,004 ft (306 m) tall. The bridge deck is a two-way 6-lane highway with a design speed of 100 km/h.

The main bridge has a navigable height of 203 ft (62 m) and a width of 891 m, which can meet the navigation needs of a 50,000-ton container ship and a 48,000-ton fleet.

The total project investment is about 6.45 billion yuan (US $1 billion).
