Architectural performance

In 2007, around the general goal of "keeping the west section open to traffic and promoting the construction of the east extension section" put forward at the beginning of the year, all the builders went up and down to Qi Xin and worked hard, basically achieving the work goal at the beginning of the year. On February 26th, 65438, the section from Xianju Chengguan to Hengxi Interchange in the west section of the project was successfully completed and put into use. As the construction scheme of the top partition wall is uncertain, Cangling Tunnel was opened to traffic as scheduled. The project of Dongyan section is progressing smoothly. After the groundbreaking ceremony was held at the beginning of the year, various works such as policy treatment and land approval were carried out one after another, and the bidding work was successfully completed in June+10, 5438. City headquarters in conjunction with the district (city) headquarters and local towns (streets) timely implement temporary land, electricity and water, so that all construction units can enter the site smoothly and start construction as soon as possible. Lingjiang Bridge, a control project, started ahead of schedule on June 13.
