Friendship Bridge II” serves as an international link connecting the countries of Lao P.D.R. and Thailand. Moreover, the Bridge provides a spectacular view of the Mekong and, with its aesthetical combination of PC sails and a tower, gives the impression of a “Wai”: two hands joined in prayer and the greeting commonly used in Laos and Thailand that represents the Buddhist culture of both countries.

 

The architectural beauty of Friendship Bridge II is a result of the aesthetic balance between the straight lines of the Bridge’s box girders, as well as the tapering of the concrete piers designed to match the shape of the pile caps so as to ensure visual conformity.
