I. Project Overview
The Xianghu Tunnel Project is the extension project of Jiuzhou Avenue across the east of Xianghu Lake, starting from Zizi Road in the west and reaching Yingbin Avenue in the east. The completion of this project can improve the current traffic congestion on roads such as Hongcheng Road and Changnan Avenue; it is necessary to accelerate the construction process of urban trunk linear roads and improve a reasonable urban transportation network system.

Project construction content and scale
The construction content of Xianghu Tunnel includes roads, traffic, structures, drainage, lighting, ventilation, construction, fire protection, electrical, landscape, ancillary facilities, management centers, etc.
The Xianghu Tunnel Project is a tunnel project through Jiushu Avenue westward through Xiangxiang Lake. It has a west length of Qiziyu Road and east to Yingbin Avenue. The total length of the route is about 2.7km, of which the buried section length is 1,725 meters. It is about 600 meters and 350 meters long.
Significance of project construction
The implementation of the project will play an important role in further improving the transportation link between the Changnan area and the new site of the Provincial Party Committee and Provincial Government, speeding up the construction of urban trunk road networks, and promoting regional economic and social development.
