The whole 25.5km project is expected to be operating in 2010. It will take only 45 minutes to travel from Pudong to Chongming, saving at least an hour.

The bridge has a projected life span of 100 years. "The piers can withstand a large ship colliding with them and the structure can cope with gales up to 133 kilometers an hour and an earthquake measuring 7.0 on the Richter scale," said director of the headquarters' bridge department Guo Zhenwen.
