Removed, rebuilt and new timber arch bridges in China

China timber arch bridge is a unique bridge structure in the world, in which the main arch ring is woven from longitudinal and transverse straight logs. This type bridge has been designated as China national cultural heritage, and its construction technique was inscribed onto the Urgent Safeguarding List of Intangible Cultural Heritage of Humanity by UNESCO in 2008. In recent years, many ancient timber arch bridges have been removed due to engineering construction such as hydropower station or rebuilt after destroyed by fire or with serious deterioration. At the same time, some new timber arch bridges have also been built by various reasons. In this paper, some removed, rebuilt and new timber arch bridges in China are presented and evaluated.
