Li Chun 's innovative spandrel-arch construction , while economising in materials , was also of considerable aesthetic merit . An inscription left on the bridge by Tang dynasty officials seventy years after its construction reads : During the next 1,400 years , the bridge survived at least eight wars , ten major floods and numerous earthquakes , the most recent being the 7.2-magnitude Xingtai earthquake in 1966 . Yet , the support structure remains intact and the bridge is still in use . Only the ornamental railings have been replaced every few hundred years
