6. Beijing Grand Bridge

Also for the sixth-longest bridge in the world is the view towards Asia. The Great Bridge of Beijing is 48.1 km long and part of the high-speed railway line between Beijing and Shanghai.The viaduct was built as a girder bridge using precast concrete components. Only the crossing of the G45 highway was spanned by a steel arch bridge hollow box girders with a span of 108 m. In November 2011, the building project was completed.

5. Bang Na Expressway

The fifth longest bridge in the world is in Thailand: The Bang Na Expressway 54 km long and can be found in Bangkok. A total of six lanes provides the toll road, in each direction three.
