It was learned a few days ago that Nanjing rail transit construction will usher in an unprecedented year of “outbreak” in 2021. 15 lines are expected to be constructed at the same time before the end of the year, with a mileage of 300 kilometers under construction. Metro Line 11, Ningma Intercity (Nanjing section), Ningyang Intercity (Nanjing section), and Ningchu Intercity (Nanjing section) are all newly started construction projects this year.
It is estimated that after 2023, the total operating mileage of Nanjing Metro will reach 593 kilometers. By 2030, 25 subway lines will be built in the city with a total length of 1011.2 kilometers.
