Recently, there have been frequent good news in the field of infrastructure construction in China. China Railway 10th Bureau Group Co., Ltd. and China Railway Construction Engineering Group Co., Ltd. stood out in the fierce market competition by virtue of their strong technical strength and reasonable quotation. They successfully won the bid for the new Hanchuan section of Hubei S109 Xiaogan Hanchuan first-class highway and the Han Dan Railway Crossing Project, and the HZDYFSG bid section of Hangzhou East Railway Station supporting ancillary facilities in Zhejiang Province, fully demonstrating the outstanding strength of CSCEC in the field of transportation infrastructure.

Among the major traffic node projects in Hanchuan, Hubei, the new Hanchuan section of S109 Xiaogan Hanchuan first-class highway will realize the interchange with Handan Railway. The length of the overpass bridge on both sides of the project is 339 meters, using innovative rotating T-shaped structure design and prestressed concrete cast-in-place box girder technology. The left side is equipped with a 2 × 70 meter rotating T-shaped structure, and the right side is equipped with a 2 × 75 meter rotating T-shaped structure, both of which adopt advanced bracket cast-in-place rotating construction technology. China Railway Tenth Bureau became the first candidate to win the bid for the project with a bid price of 109052240 yuan, fully reflecting the professional advantages of the enterprise in the field of complex bridge engineering construction. The project is constructed according to the standard of first-class highway, with a design speed of 80 km/h, six lanes in both directions, and a bridge design reference period and main structure design working life of 100 years. After completion, it will greatly improve the traffic efficiency of the regional traffic network.

At the same time, in Hangzhou, an important transportation hub in East China, the construction of supporting facilities for Hangzhou East Station has also begun. The project is located on the northwest side of Hangzhou East Railway Station, with a total land area of approximately 20964 square meters. Five supporting buildings are planned to be constructed, with a total construction area of 36493 square meters. After the completion of the project, it will provide 324 single dormitories and 360 crew apartments, totaling nearly 1400 beds, and be equipped with 123 motor vehicle parking spaces, further improving the service functions of Hangzhou East Station. China Railway Construction Engineering Group has successfully won the bid with an evaluation price of 224.247715 million yuan, and will undertake the construction task of this important livelihood supporting project.
