Puliter Bridge is a super-large bridge on Puxuan Expressway with a length of 1040m and a main span of 628m. The bridge is located in a steep terrain, complex climate, difficult hoisting and high safety risk, which is called another challenge by domestic and foreign engineers. After 36 months of construction, the whole project has been completed. When you drive past, you will be shocked by the magnificent bridge standing above the Puli Grand Canyon.
