Starting from the development prospect of the central city, Nantong Rail Transit Line 3 has designed four lines with a total length of 180 km. According to the website of the Provincial Planning Department, the newly planned Nantong rail transit planning line starts from Tiansheng Port in the west and ends at Sutong Park in the east, with a total length of 41.1km; Rail Line 4 runs from Jinsha South to Jiangshan Road, the development zone of the city, with a total length of about 38.4 kilometers. According to the deployment of the municipal party Committee and municipal government, we are actively promoting the preparation of a new round of construction planning, and strive to report it to the National Development and Reform Commission as soon as possible. The new round of construction planning will focus on connecting the new airport, important external hubs along the Yangtze River in the north and important urban areas such as Tongzhou and Haimen, and support Nantong to upgrade its energy level and integrate into the Yangtze River Delta faster and better. So there is still a chance.
