The Line 1 of Wuhan Metro is an elevated metro line in the city of Wuhan, Hubei. It is the longest continuous metro viaduct in the world.
Line 1 opened on 28 July 2004, making Wuhan the fifth city in mainland China to have a metro system after Beijing, Tianjin, Shanghai and Guangzhou.
This is the first Metro line in China incorrectly referred to as a light rail line in Chinese terminology because it is elevated.
Originally a branch line was planned to cross the Yangtze to Wuchang District via the Second Wuhan Yangtze River Bridge.
Covering a distance of about 38 kilometers (24 miles), Wuhan metro line 1 totally passes 32 stations and takes around 75 minutes to finish a single trip. It connects Jinghe and Hankou North, passing Dongxihu, Qiaokou, Jianghan, Jiang’an and Huangpi Districts.
