Adding Tangshan Road Interchange and Connecting Line Project to Qingyin Expressway

According to reports, the Tangshan Road interchange and connecting line project will be added to the Qingyin Expressway, connecting Chongqing Road Overpass in the west and Tianshui Road in the east, with a total length of about 3 kilometers. Except for the tunnel crossing the mountain section, the two-way six-lane main and auxiliary roads are adopted. The main line crosses Wenchang Road from west to east in the form of an elevated road, and then passes through Tiger Mountain in the form of a tunnel. After that, an interchange is set up to connect with Qingyin Expressway, and a toll station at the entrance and exit of Qingyin Expressway is added. , The estimated total investment of the project is 3.26 billion yuan. The project is invested and constructed by Qingdao Transportation Development Group, a subsidiary of Qingdao City Investment Group.

The construction of Tangshan Interconnection and Connecting Line Project on Qingyin Expressway is highly comprehensive and difficult to construct; the relocation of pipelines requires a large amount of engineering and is difficult; the construction period for existing expressways and urban arterial roads is long, and the coordination and management are complicated ;The project is located in the built-up area of the city, adjacent to the residential area, and has the characteristics of high environmental protection and safety requirements. It is estimated that more than 1,200 people will be invested during the May 1st Labor Day, entering the peak period of work. It is planned that the underground excavation section at the west entrance of the tunnel will be constructed in May, and the construction at the east entrance of the tunnel will be carried out in June.

The Tangshan Road Tunnel of this project is a construction period control node project, which has the characteristics of multiple sections, small clear distance, and super large span complex. Among them, the maximum excavation span is 31.56m, and the maximum section is 472 square meters. It is the largest excavation span in China under construction. traffic tunnel.

This project is a key project of urban renewal and urban construction for three years. It is the fourth horizontal of the seven-horizontal and nine-vertical express road network in the "Qingdao City Center Urban Road Network Planning", and is an important part of the road network structure of the central urban area. The total construction period of the project is 24 months, and strive to realize the opening of the tunnel in September 2024, and realize the opening of the whole line to traffic ahead of schedule by the end of 2024.
