The Shanghai-Chongqing Highway has now been completed with the trial opening of the 320km-long Hurongxi section in Hubei province. Construction of this mountainous section started in 2002, and includes 370 bridges and 46 tunnels. It involved an investment of Rmb20.4bn.

The 1,900km-long Shanghai-Chongqing National Highway has reduced travel time between the two municipalities to about 17 hours.
