The whole construction was divided into two parts, being phase 1 and 2, which opened in 2013 and 2014, respectively. Phase 1, opened on December 28, 2013, runs through Wuchang in a northeast-southwest direction, connecting Wuhan Railway Station, Wuchang Railway Station and major commercial districts.^[3] Phase 2 opened a year later and runs in an east-west direction, linking Hanyang and Wuchang, tunneling through the Yangtze river in the proximity of the first Yangtze river bridge and connecting with phase 1 at Wuchang railway station.^[4]

The opening of phase 1 of Line 4 will form the skeleton of Wuhan's metro system. Right after its opening, the system (including Line 1, 2, and 4) will be able to accommodate millions of passengers a day, where a large proportion of them will be the cross-Yangtze passengers. But all stations on line 4 have been designed only to accommodate a six-car train (type B) in length and have no possibility to extend for future upgrading.
