大湾区携手北部湾 广州至湛江高铁建成通车

Core Viewpoint - The Guangzhou-Zhanjiang High-Speed Railway (GZHSR) has been completed and opened for operation, significantly reducing travel time between the North Bay city cluster and the Guangdong-Hong Kong-Macao Greater Bay Area, thus supporting high-quality regional economic and social development [1][2] Group 1: Project Overview - The GZHSR connects multiple cities including Guangzhou, Foshan, Zhaoqing, Yunfu, Yangjiang, Maoming, and Zhanjiang, with a designed speed of 350 km/h and a total length of approximately 401 kilometers [1] - The project includes significant engineering feats such as the Zhujiang Four-Line Bridge and the Zhanjiang Bay Railway Undersea Tunnel, which is 9,640 meters long, allowing trains to traverse it in about 3 minutes [1] - The construction utilized an intelligent management system for shield tunneling, overcoming technical challenges and achieving tunnel completion in 33 months [1] Group 2: Future Connectivity - Following the opening of the GZHSR, future connections with the He-Zhan High-Speed Railway and the Zhanhai High-Speed Railway will create a continuous high-speed rail corridor along the coast, linking the Yangtze River Delta, North Bay, and Hainan Free Trade Port [2] - This development is expected to enhance the connectivity between the Guangdong-Hong Kong-Macao Greater Bay Area, North Bay city cluster, and Hainan Free Trade Port, forming a "golden corridor" for regional coordinated development [2]
