At 24:00 on December 31, 2020, the Sichuan Chengdu-Yibin Expressway, which was built by Zhongjian Road and Bridge Group, was officially connected to the grid.
It is reported that the Chengyi Expressway is an important traffic node in the southwest region of the national "two horizontal and three vertical" development axis, and is an important southbound passage project of the "South Gate" of Dechuan and the "bridgehead" of the River and the Sea. The project starts from the Chengdu Economic Zone Ring Expressway, docks with the south line of chengdu new airport expressway, passes through Chengdu Jianyang City, Meishan City, Neijiang City, Zigong City, Yibin City, and ends at the Zhongfeng Temple Hub Interchange in the western section of Yibin Transit Expressway, with a total length of about 157 kilometers, a roadbed width of 34.5 meters, a two-way six-lane road, and a design speed of 120 kilometers per hour, which is one of the widest and highest standard highways from Chengdu to various cities (states), with a total of 37 large and medium bridges and 17 interchange interchanges.
The ZCB2-3 section of Chengyi Expressway, which is built by Zhongjian Road and Bridge Group, is about 25 kilometers long, with a total of seven bridges, requiring a total of 881 prefabricated T-beam plates, including 359 30-meter-long T-beams and 522 40-meter-long T-beams. The project started construction in 2018, and all the participants carried forward the spirit of hard-working, dare to fight and dare to fight, and achieved the goal of opening to traffic in four years and three years. Especially in 2020, in the face of the sudden outbreak of new crown pneumonia, the project builders planned ahead and took the initiative to grasp the epidemic prevention and control on the one hand, and the construction and production on the other hand, carried out detailed technical and safety communication for the high-risk and professional nature of the girder operation, and strictly implemented the on-site on-site and full-time safety personnel on-site inspection system of the project team members to ensure that the quality of the T beam erection was controllable, the progress was controllable and the safety production was controlled, which won time for the bridge deck paving construction of the project and laid the foundation for the opening of the road at the end of the year.
The opening of the Chengyi Expressway plays an important role in improving the traffic conditions along the route, strengthening the external radiation capacity of Chengdu's comprehensive transportation main hub, and promoting regional economic and social development.
