Chongqing West Railway Station, located in Shapingba District, Chongqing, China, is the largest passenger transport hub system in western China. It is a comprehensive transportation hub with railway as the mainstay, integrating long-distance buses, public transportation, rail transit and other transportation modes. Yuxin Company participated in the construction in 2019 and was responsible for undertaking its municipal supporting road traffic engineering. After five years of construction, it was completed and opened to traffic. The number of traffic conversions has set a record for similar projects in China, marking that Chongqing Yuxin has taken the lead in achieving full coverage of traffic engineering construction scenarios such as highways, plateau highways, urban high-speed railways, airports, public transportation, parks, bridges, tunnels, main and secondary roads, etc.

　　Luzhou Linyu Yangtze River Bridge and Connection Line Project is an important part of the Second Ring Road in Luzhou City. The bridge is 1,723 meters long, with eight lanes in both directions and a total length of 7.512 kilometers. It is the world's largest highway-railway dual-use three-tower cable-stayed bridge, and its electromechanical and transportation engineering projects are contracted by Yuxin Company. The project was completed and opened to traffic at midnight on December 20, 2023, marking the completion of the entire Second Ring Road in Luzhou City.

It is another exemplary project of good cooperation with Gezhouba Group after projects such as Chongqing Third-ring Jiangjin-qijiang Expressway and Gansu Pinghua Expressway, and has won the honorary title of advanced unit in quality management. So far, Yuxin Company has been rated as A in credit evaluation for six consecutive years in Gezhouba Group, maintaining the title of "green list subcontractor" of China Gezhouba Group.

　　The Chongqing Second Horizontal Expressway project is an important part of Chongqing's "six horizontal and seven vertical" expressway network, and its smart operation system project is contracted by Yuxin Company, which is the company's first market-oriented software business led by itself. By building "big data of the open-to-traffic road segment model" and creating a smart operation management system with "one brain, two data centers, and eight functional modules", the company integrates the operation and management of Chongqing's Second Horizontal Expressway, achieving centralized and unified management of the entire process, area, and life cycle of road operation. This makes the operation and maintenance management more intelligent and efficient, playing an important role in improving the efficiency of road operation management. Among them, the system has built a project safety intelligent monitoring and warning system, which is the first time in Chongqing to realize real-time data analysis and advance warning of tunnel, bridge, high slope displacement, deformation, etc., providing strong technical support and intelligent operation and maintenance guarantees for the safe operation of the project. The project was put into use in November 2022, marking a substantial breakthrough in Yuxin Company's active expansion of post-construction services and digital transformation, laying a solid foundation for forming a virtuous cycle of industrial development.

　　Ganyue Avenue is an urban trunk road, starting from Shajingwan Interchange in the west and ending at Chengnan Interchange in the east. It is the western extension of the "Airport South Connection Line" and located in the western section of the planned "Twelve Connection Lines". It is located within the Liangjiang New Area, between Lianglu and Lijia clusters, between the outer ring expressway and the first horizontal line. The road runs from east to west, starting from the Wuzong Line (Airport Road) Interchange connecting to the Airport South Connection Line in the east, and connecting to the Yuelai Convention and Exhibition Center area road network through the Sijong Line Shajingwan Interchange in the west.

　　The project of Jialing River Bridge and Approach Span of Jiangjun Road, Nanchong City, as well as the Reconstruction Project of Petroleum East-West Road mainly includes the road landscape, waterscape engineering, lighting engineering, and the mechanical and electrical communication engineering of the reconstruction project of Petroleum East-West Road. Among them, the waterscape engineering of this project is the first in China to introduce musical dancing fountains and digital water curtains into cross-river bridges, which is the largest waterscape engineering in China. Facing the unfavorable conditions of an ultra-short construction period, concurrent design and construction, no similar precedents in China, and all construction interfaces being high-altitude and confined space operations, the project management team of Yuxin Company carefully coordinated and optimized the organization. Finally, the project was completed and opened to traffic in 36 days of effective construction period, setting a national record for waterscape construction. It was highly recognized by local governments and the public, marking a new level of the company's project implementation capabilities.

The Jiangjin-Qijiang Expressway is part of the Chongqing Third Ring Expressway, with a total length of about 48 kilometers and a design speed of 80 kilometers per hour.

The Zhaomushan Mountain Starlight Tunnel is an important part of the North Line of Xingguang Avenue, and is a newly-built urban tunnel closest to the core area of the main city of Chongqing. After opening to traffic, the North Line of Avenue of Stars will connect Dazhulin area, Zhaomushan area, Fortune Center area, Xinpaifang area and even Lijia area. It will accelerate the development of transportation in these large areas and promote economic smoothness between them and the core areas of the main city.
CICO is responsible for its tunnel lighting project. The tunnel's lighting adopts "intelligent lighting control", and chooses a dimming scheme according to changes in traffic volume and changes in brightness outside the tunnel, which integrates environmental protection, energy conservation and nature.
The unique "starlight" design on the top of the tunnel is a highlight. The "starlight" composed of more than 13,000 small LED lamp beads creates the feeling of "night sky" on the top of the tunnel, which echoes the name of "starlight tunnel".
