                                            Hangzhou Bay (海湾) Bridge

     The world's longest trans-oceanic bridge (跨海大桥) started to be built four years ago in Cixi in Zhejiang

Province. Thanks to the workers' hard work, the first main step of the bridge will be finished-the southern part

and the northern one will be connected in June in 2007. In 2008, people can drive their cars on it.

     Hangzhou Bay Bridge will be 36 kilometers long. It will cost about RMB 11. 4 billion, 35% of which is

offered by many personal companies in Ningbo, and 59% is loaned (贷款) from China's different banks.

     It usually takes people over four hours to travel from Shanghai to Ningbo by car. Now the bridge will make

the journey short by 120 kilometers, making it a 179-kilometer journey. So the bridge will make the trip faster

and easier. The drive between Shanghai and Ningbo will be less than 2 hours. On the other hand, the

development is so fast that more and more foreign companies in Shanghai like to make money in Ningbo. In the

future, Ningbo and northern Zhejiang will be parts of the greater Shanghai economic zone (经济圈).
