Recently, a citizen called the 12345 government service hotline to oppose the establishment of "Jiangxinzhou North Station" on Nanjing Metro Line 4 Phase II. On February 25, a reporter from Modern Express learned from Nanjing Metro Construction Co., Ltd. that whether to set up a station on Jiangxinzhou for Line 4 Phase II remains to be further studied and determined.
The Line 4 Phase II project starts from Longjiang Station of Phase I, crosses the river westward, then runs westward along the planned Central Avenue and Puma Road, and ends at Zhenzhuquan Station, with a total length of about 9.7 kilometers.
In November 2016, the National Development and Reform Commission issued the "Reply of the National Development and Reform Commission on the Adjustment Plan for the Second Phase Construction Plan of Nanjing Urban Rail Transit (2016-2021)". The reply mentioned deepening the study on the feasibility and necessity of setting up a station on Jiangxinzhou Island for the Line 4 Phase II project. As a result, the news that Line 4 Phase II is expected to have a station on Jiangxinzhou Island has been hotly discussed among citizens.
The reporter learned that some citizens oppose the establishment of a station on Jiangxinzhou for Line 4 Phase II. Their reason is that the excavation of the foundation pit for Jiangxinzhou North Station will largely pass through silty fine sand layers and mucky silty clay. These soil layers have good permeability, contain confined water, and the groundwater is directly connected to the river water, with abundant water supply and an infinite recharge. During the excavation of the foundation pit, once water seepage occurs around the pit or at the bottom, the water flow will carry out fine sand particles from the stratum, causing the permeability coefficient of the stratum to increase by orders of magnitude, which may lead to risks such as water and sand gushing in the foundation pit. In addition, the excavation of the foundation pit may cause risks such as settlement and deformation of the Yangtze River levee.
On the contrary, residents in the northern section of Jiangxinzhou are very much looking forward to Line 4 Phase II. According to staff from Nanjing Metro Construction Co., Ltd., a heavy snow before the New Year reduced buses and made it difficult to drive cars, so residents in the northern section of Jiangxinzhou had to walk in and out of the island, suffering a lot. At that time, many citizens called the 12345 government service hotline to request an additional station on Jiangxinzhou for Line 4 Phase II, so that the northern section of Jiangxinzhou could have metro access as soon as possible.
So, will Line 4 Phase II have a station on Jiangxinzhou or not? According to staff from Nanjing Metro Construction Co., Ltd., in accordance with the requirements of the second round construction plan adjustment reply, Metro Line 4 is currently further deepening the study on the feasibility and necessity of setting up a station on Jiangxinzhou, and whether to set up a station remains to be further studied and determined.
