南京新生圩长江大桥昨正式通车 全市已建成13处15条过江通道

Core Viewpoint - The opening of the new Xinshengwei Yangtze River Bridge significantly enhances connectivity in Nanjing, reducing travel time across the river from one hour to ten minutes, and marks a shift from a "separated" to a "integrated" urban landscape [1][2]. Group 1: Infrastructure Development - The Xinshengwei Yangtze River Bridge is the sixth free river crossing in Nanjing, contributing to a total of 15 river crossings in the city, which facilitates urban integration [1]. - The bridge spans approximately 13.17 kilometers and serves as a crucial hub connecting Qixia District, Jiangbei New Area, and Liuhe District [1]. - The bridge is part of Nanjing's "high-speed road system" and helps alleviate traffic pressure on existing routes while promoting development in surrounding areas [2]. Group 2: Engineering and Technology - The bridge features a main span of 1,760 meters, making it the first in China and the third in the world of its kind, showcasing advanced engineering techniques [2]. - The construction involved overcoming several world-class technical challenges, providing a valuable "Nanjing solution" for similar bridge projects [2]. Group 3: Future Developments - Four additional river crossings are currently under construction in the Nanjing section of the Yangtze River, with key project milestones being achieved [3]. - The focus for the "14th Five-Year Plan" includes the development of multiple railway and metro river crossings, aiming to enhance the connectivity of the urban transport network [3]. - By the end of the "14th Five-Year Plan," the total number of river crossings in Nanjing is expected to reach 15 (17 routes), creating a more balanced, three-dimensional, and convenient cross-river transportation system [3].
