San Van Bridge in Macau has been inaugurated ahead of its opening to traffic next month. The ribbon was cut by China's president Hu Jintao and Macau's chief executive Edmund Ho Hau Wah as part of ceremonies marking the 5th anniversary of Macau's return to China. The 2.2km cable-stayed bridge has been the largest project in the special administrative region. There are two decks in the US$70 million structure, with the enclosed lower section reserved for use during typhoons. A light rail system may also be installed.
