# Line 4 (Wuhan Metro)

The Line 4 of Wuhan Metro (Chinese: 武汉地铁4号线) is the third line in Wuhan Metro system, and it will be the second metro line crossing the Yangtze river in Wuhan. It is colored grass-green, which is the identifying color of this line, which would appear on its trains, station signs, and the official subway map.
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. 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.
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.
