长江干线武汉至重庆4.5米水深航道贯通

Core Points - The Yangtze River mainline from Wuhan to Chongqing has achieved a full connection with a navigable depth of 4.5 meters, allowing 5,000-ton vessels to reach Chongqing year-round, marking a significant enhancement in the navigational capacity of the Yangtze Golden Waterway [1] - This section of the waterway is a crucial part of the national comprehensive transportation network and plays a strategic role in improving the overall efficiency of the Yangtze Golden Waterway [1] - The waterway previously faced multiple "bottlenecks," particularly during dry seasons when some sections had insufficient depth, requiring vessels to reduce their load to pass [1] Economic Impact - Each 0.1-meter increase in water depth allows vessels to carry approximately 200 tons more cargo, reducing logistics costs by about 14% and increasing profits by 12% [2] - The full connection of this waterway section is projected to generate direct economic benefits of approximately 1.6 billion yuan and indirect economic benefits of about 15.9 billion yuan annually, providing strong momentum for the high-quality development of the Yangtze Economic Belt [2]
