copyright Summary Students learn about the variety of materials used by engineers in the design and construction of modern bridges. The tradition has declined however in recent years due to rapid urbanization, scarcity of timber and lack of available construction space, all of which combine to threaten its transmission and survival. 30 minutes Subject Areas: Suggest an edit Concrete is made from cement, aggregate and water. The cultural space created by traditional Chinese arch bridges has provided an environment for encouraging communication, understanding and respect among human beings. Its weight pushes the surrounding rocks down and outward, making entire structure very rigid and strong.

The craftsmanship is passed on orally and through personal demonstration, or from one generation to another by masters teaching apprentices or relatives within a clan in accordance with strict procedures. The carpentry is directed by a woodworking master and implemented by other woodworkers.
The traditional design and practices for building these bridges combine the use of wood, traditional architectural tools, craftsmanship, the core technologies of ‘beam-weaving' and mortise and tenon joints, and an experienced woodworker's understanding of different environments and the necessary structural mechanics. Wooden arch bridges are found in Fujian Province and Zhejiang Province, along China's south-east coast.
