武汉地铁12号线二期开通，亚洲最长地铁环线实现闭环

10月29日，武汉地铁12号线二期正式投入初期运营，并与已通车的一期工程完成贯通 1。这一节点标志着全长59.9公里、设站37座的武汉地铁12号线全线闭环，使其成为亚洲最长的地铁环线 1。该线路首次实现了武昌、汉口、汉阳“三镇”及7个中心城区的串联，并在建设过程中两次下穿长江、一次下穿汉江 1。

随着12号线二期的开通，武汉轨道交通网络运营总里程达到581公里，车站总数增至351座 1。新线路不仅衔接了汉口站和武昌站两大铁路枢纽，还具备与18条既有及规划线路换乘的能力 1。此举有效缓解了长期存在的跨江通勤压力，推动武汉轨道交通进入“环射贯通”的新格局 1。据统计，武汉地铁线网累计总客运量已超过130亿乘次，最高日客运量为602.2万乘次，全市公共交通客运量分担率占比超过70% 1。

Wuhan Metro Line 12 Phase II officially commenced initial operations on October 29, merging with the previously opened Phase I to complete a continuous loop 1. This newly closed circuit spans 59.9 kilometers and includes 37 stations, making it the longest subway ring line in Asia 1. The project involved entities including China Railway Development Investment Group and China Railway Construction Investment Group, marking a significant milestone for the city's public transit network 1.

The completed line is the first to seamlessly connect Wuhan’s three historic towns—Wuchang, Hankou, and Hanyang—as well as seven central urban districts 1. By linking major railway hubs at Hankou Station and Wuchang Station, the route offers transfers to 18 existing or planned lines, significantly alleviating long-standing cross-river commuting pressures 1. The infrastructure engineering involved crossing under the Yangtze River twice and the Han River once 1.

With the full integration of Line 12, Wuhan’s total operating rail mileage has reached 581 kilometers across 351 stations 1. This expansion places the city into a new "ring and radial" transportation pattern, enhancing overall connectivity and capacity 1. Historically, the metro system has recorded over 13 billion passenger trips, with a single-day peak of 6.022 million, while public transport accounts for more than 70% of the city's total passenger traffic share 1.
