      Not long ago, China decided to build a bridge to link Zhuhai, Hong Kong and Macao. People will finish
building it in 2016. It will be the world's longest sea-crossing bridge!
     The Y-shaped bridge is about 50 kilometers altogether. 35 kilometers of it will be over water.
     Officials say the bridge we use will last in good condition for 120 years. It can handle big earthquakes
as well as strong winds. And it will be all right even if it is hit by a 300,000-ton ship.

to drive from Zhuhai or Macao to Hong Kong.
     Some people worry that the building of the bridge will pollute the sea and hurt sea animals. Officials
say they will protect the ocean.
