    What was the highlight (亮点) of last May Day? It was Hangzhou Bay (海湾) Bridge, which opened on

that day.

     It is 36 kilometers long and the world's longest cross-sea bridge. It begins at Jiaxing, crosses the East

China Sea, and ends at Cixi, about 70 kilometers from Ningbo. It will reduce (减少) the driving time

between Shanghai and Ningbo by about two hours.

    A great number of the workers started to build it on November 2003, and ended in June 2007. Now the

bridge has become well-known. About 40,000 vehicles (交通工具) can cross the bridge each day at first.

This will be added to (增加到) 100,000 vehicles a day in 2026. During the May Day holiday, many private

car owners came to the bridge as well as tourists on coaches. So many people wanted to see the bridge

with their own eyes.

    As a shortcut between Zhejiang and Shanghai, the bridge will not only improve traffic but also help

economic development (经济发展) in the Changjiang River Delta.

    "People enjoy working in small cities like Cixi but living in big cities like Shanghai," said a man. "With the

help of the bridge, they can leave Shanghai for Cixi in the morning and go back in the afternoon. It's only

about one and a half hours' drive."
