On June 22, 2022, the feasibility study report of the third phase of Dongguan Metro Line 2 was approved by the Provincial Development and Reform Commission. It is worth noting that the approval document revealed that the total construction period of the third phase of Line 2 was only 54 months. Converted, it is four and a half years (in the official documents released before, the construction period of this line was expressed as about five years).

In addition, a tender document recently issued by Dongguan Public Resources Trading Network (the tender for the third-phase project cost consulting service project of Metro Line 2) also revealed the planned construction period of each stage of this line, of which the total construction period is about 4.5 years. This also means that the construction period has been shortened by about half a year: it is expected that the trial operation of Humen People's Exclusive Subway will begin at the end of 65438+February in 2026.
