The golden autumn season is the golden period for engineering construction. The reporter learned that with the steady progress of construction, new progress has been made in the construction of multiple transportation infrastructure projects in multiple regions. In Heilongjiang, at the construction site of No. 2 Super Major Bridge of Harbin-Yichun High-speed Railway, with the last box girder weighing 715 tons and 32 meters long hoisted to the designated location, the beam erection construction of the first project of Harbin-Yichun High-speed Railway section was completed. According to Yang Xushu, the project leader of China Railway 22nd Bureau, the Harbin-Yichun High-speed Railway, consisting of Harbin Tieli Section and Tieli Yichun Section, is the northernmost high-speed railway under construction in China and the first high-speed railway crossing permafrost regions in China. In the construction of the Tieyi section, the project team developed a special construction plan to overcome multiple technical difficulties such as soft soil roadbed and frozen soil roadbed, accumulating valuable experience for the construction of high-speed railways in permafrost regions of China. In Xinjiang, after 90 minutes of clockwise rotation, the largest swivel bridge in Xinjiang, the Yanbei Viaduct on the East Second Ring Road of Urumqi City, constructed by China Communications Second Highway Engineering Co., Ltd., successfully completed the swivel. At this point, the East Second Ring Road of Urumqi is fully connected. According to Zhang Bo, the project leader of China Communications Second Highway Engineering Co., Ltd., the Yanbei Viaduct spans the Lanxin Railway, with a rotating section weighing 16500 tons. During the swivel construction, the project team utilized intelligent traction equipment to monitor the swivel situation in real-time, adjust the swivel speed, and ultimately achieve a 77 degree "turn" in the air of the swivel bridge. In Inner Mongolia, the electrification renovation project of the Jitong Railway, undertaken by China Railway Electrification Bureau, successfully closed the continuous beams of the Jingpeng Super Large Bridge. This is also the first super large bridge on the entire line to achieve continuous beam closure, marking significant progress in project construction. The Jitong Railway starts from Ulanqab City in Inner Mongolia to Tongliao City in the west and is an important energy channel for the "Mongolian coal transportation to the east". According to Wang Xiaowei, Deputy Chief Engineer of China Railway Electrification Bureau, the Jingpeng Super Large Bridge is about 2374 meters long and spans National Highway 303, making it one of the key and difficult projects for the entire Jitong Railway line. In Jiangsu, the construction of the front 3 section of the Shanghai Suzhou Lake Railway Station, which was participated in by China Railway 19th Bureau, successfully completed the installation of 979 box beams in the section, marking the completion of the installation of box beams in the Jiangsu and Zhejiang sections of the Shanghai Suzhou Lake Railway, laying a solid foundation for the next step of ballastless track construction. According to Zou Deyu, the project leader of China Railway 19th Bureau, the Shanghai Suzhou Lake Railway starts from Shanghai Hongqiao Station, passes through Suzhou City, Jiangsu Province, and ends at Huzhou Station in Huzhou City, Zhejiang Province. The main line has a total length of approximately 163.8 kilometers and a design speed of 350 kilometers per hour. After the project is completed and put into operation, it will further improve the road network layout in the Yangtze River Delta region, effectively relieving the transportation pressure on the Shanghai Nanjing and Shanghai Hangzhou railway channels. In Zhejiang, the successful completion of the Bijia Tunnel on the Jinjian High Speed Railway, undertaken by China Railway 24th Bureau, marks significant progress in another milestone project of the Jinjian (De) High Speed Railway. Jinjian High speed Railway, with a total length of about 64 kilometers, is an important part of the "Mount Huangshan Jinhua" railway channel in the national high-speed railway network. According to Zhang Weijian, the project leader of China Railway 24th Bureau, the Bijia Tunnel connects two county-level cities, Lanxi and Jiande, with a total length of about 560 meters. During construction, facing the challenge of frequent changes in the surrounding rock of the tunnel, the builders adopt advanced geological prediction and early warning, strengthen the frequency of monitoring and measurement of the surrounding rock, and ensure smooth and efficient tunnel excavation. In Hubei, the Xiangbei Railway Station was built by China Railway 11th Bureau
