This adjustment involves phase I of Metro Line 1 and phase I of Metro Line 3, with a total length of 109 kilometers and a total investment of 74.784 billion yuan. Phase III of Line 2 is to be constructed as scheduled. It is expected that the city's urban rail transit's total mileage will reach 164 kilometers when fully completed.

It is 57.5 kilometers long and passes through 10 towns and districts, including Wangniudun, Hongmei, Daojiao, Wanjiang, Nancheng, Dongcheng, Dalingshan, Songshan Lake, Dalang and Huangjiang.
