An area of 45,096 square meters will be required for the metro tunnel; 14,865 sqm to construct stations, and 69,793 sqm as temporary land area. The corridor will have a total of 15 stations, 11 of which will be underground. In addition, 69,793 sqm will be needed as a "temporary land area" for the corridor. The approval will help DMRC in taking the project forward. Delhi Metro's Aerocity-Tughlakabad corridor being built as part of the Ph-IV project has been christened as 'Silver Line' by the DMRC. This will be the 10th corridor of the network, so it will also be called Line 10. The DMRC has taken a lot of efforts to minimize the impact of the construction of the Aerocity-Tughlakabad line on the Ridge areas.
The RMB has asked the forest department and the DMRC to explore other alternatives so that minimum ridge area is affected. Two more alternatives were suggested to the RMB - one where 9,136 trees were proposed to be cut and the other which required cutting of 9,831 trees. Considering all these factors, the RMB found that the earlier proposal was suitable and give a green signal to the metro line to pass through the ridge area.
