The Line 2 of Wuhan Metro is the first underground metro line crossing the Yangtze River. The line started its trial run on September 25, 2012, and officially opened on December 28, 2012. It is Wuhan's second metro line after Line 1, and the city's first underground line, since Line 1 is mostly elevated. Line 2 runs in a northwest–southeast direction, connecting Hankou and Wuchang, including Hankou Railway Station and major commercial districts.

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. The Second Wuhan River Bridge even had a provision in the central median where Line 1 trains would run in anticipation for the branch line when it opened in 1995. However, by 2003 the reservation was removed to allow for more traffic lanes when the bridge was undergoing renovation.
