Currently, the DMRC is undertaking construction work on 65.2 km of three priority corridors spanning 45 stations under the project — Janakpuri West-RK Ashram Marg (28.92 km), Majlis Park-Maujpur (12.55 km), which are extensions of the already operational Magenta Line and Pink Line, and Tughalakabad-Aerocity (23.62 km) that is being built as ‘Silver Line’, connecting the operational Violet Line and Airport Line from the respective ends.
The Union Cabinet in March 2019 had approved three out of the six corridors of the Delhi Metro’s phase 4 which will further improve connectivity in the national capital.
The other three proposed corridors which have not yet been approved by the Union Cabinet are Rithala-Bawana-Narela, Inderlok-Indraprastha and Lajpat Nagar-Saket G Block.
