The Chongqing Expressway Project has provided significant development space for sustainable urban growth in Chongqing and optimized the local transportation network.

The City’s busy urban expressway serves both the surrounding urban areas and the needs of long-distance through traffic. It comprises five horizontal, six vertical, one ring and nine connection roads. The total length of the expressway is 14.3 kilometers. Its red line has a width of 64 meters and incorporates six lanes of traffic.

With a design speed of 80 kilometers per hour, the expressway also includes one particularly large bridge, the Jialing River Bridge, as well as nine interchange bridges and three road tunnels.

Project Highlights:

  • Taking into consideration the City’s layout, the current land usage planning policy, and the extensive needs of Chongqing’s motorized population, the expressway was designed to go around the city center rather than to divide it.
  • The transportation hub, which facilitates the transfer of traffic modes, was established in accordance with the principles of "traffic volume oriented", "positive guidance" and "efficient connection".
  • An environmental impact analysis was undertaken to identify the issues arising from the construction phase. This analysis was used to minimize the impact upon the local population, and led to a series of curved alignments rather than simple alignments in order to protect established trees and local historical areas.
