The main tower of Sichuan Bank is located in the valley bank of Xiluodu Hydropower Station reservoir area in Kahaluo Township, Leibo County, Liangshan Prefecture.，The height from the bridge deck to the water surface is 110 meters.，That's 36 stories tall.，The construction is divided into 32 sections.，Reservoir bank geology is complex and changeable.。To ensure the quality of construction，The project construction team works together to tackle key scientific and technological problems，Super deep and large pile foundation is adopted for the construction of the main tower foundation of the bridge+Structural form of pile body combined with grouting，Ensure the safety of bridge structure。After the completion of the Kahaluo Jinsha River Bridge，Will be greatly shortened“Sichuan and Yunnan”The space-time distance between the people on both sides of the Taiwan Strait，Rewrite the History of Cross-Strait Interchange by Ferry，Promote the effective use of local characteristic resources，Help the Rural Revitalization of Liangshan。

The reporter learned，The expressway along the Yangtze River in Sichuan is the largest single investment in the history of expressway construction in China.、Through four world-class cascade hydropower stations and several strong earthquake fault zones、Most types of bridges with special structures、The branch line construction mileage is the largest expressway project in Sichuan.，The ratio of bridge to tunnel in Yijin section is as high as 92%，It is the first high-speed project under construction in the province at present.，The expressway along the Yangtze River is scheduled to be completed and opened to traffic in 2025.。
