Kunshan-Wujiang section of Changjia Expressway is an important part of "Vertical One" in Jiangsu Province's "Five Vertical, Nine Horizontal and Five Connections" expressway network, and it is also an important part of Suzhou Expressway network. After the completion, vehicles from northern Suzhou to southern Zhejiang can continue to move forward from the east section of the Ring Expressway without bypassing Sujiahang, thus diverting the traffic of Sujiahang, which has a huge traffic volume. Its construction will effectively alleviate the traffic pressure of Sujiahang Expressway.
The Kunshan-Wujiang section of Changjia Expressway, known as the second Sujiahang, was officially launched and is expected to be completed and opened to traffic four years later. After completion, this section of expressway will effectively alleviate the traffic pressure of Sujiahang Expressway and greatly shorten the time from Kunshan to Wujiang.
Meaning function
With the opening of Changjia Expressway, the traffic pressure of Sujiahang Expressway will be effectively relieved, and the service level of expressway network in our city will be greatly improved, which is of great significance to strengthen the economic and social ties between Jiangsu and Zhejiang provinces and accelerate the urbanization process along the route. In addition, the project will shorten the route of the national coastal highway in this area by more than 20 kilometers after it is completed simultaneously with the second phase of the northern expressway of Zhejiang Hangzhou Bay Bridge in the south.
