Overall Scheme Design of Lishui Bridge South Extension Elevated Project in Zhangjiajie

The elevated south extension of Lishui Bridge in Zhangjiajie connects the both sides of Lishui, and is one of the main north-south trunk roads in the urban area. Comparing and studying from five aspects of project background, engineering situation, functional orientation and main technical standards, overall scheme, and node scheme, the designs of elevated bridge and interchange node are completely introduced. This project is of great significance for perfecting the urban backbone road network system, improving the current traffic congestion nodes, and strengthening the connections between both sides of Lishui River.
