Boulevard Of Smiles

2009-9-17

THE Expo Boulevard will display people's faces with smiles on its six horn-like structures, known collectively as Sunny Valley, which will be similar to a section of the opening ceremony of last year's Beijing Olympics, according to an Expo official on the project.

The facade of the valleys, each about the size of two basketball courts, would be covered by LED lamps that each can display more than 10,000 colors, said Zhao Keping, assistant boulevard director.
