The four stations such as Mehrauli, Lado Sarai, Kishangarh and Masoodpur falling in the Phase IV (Tughlakabad to Aerocity corridor) have been removed from the plan due to the permissions denied by Archeological Survey of India (ASI). The stations will no longer be a part of this section as the (ASI) has not given clearance for the four stations saying the route are falling on the archaeological sites.

The four station are part of the Phase IV corridor (Tughalakabad to Aerocity), which first contract has been recently awarded for the construction of Metro viaduct from Sangam Vihar to Saket - G including four elevated Metro stations - Sangam Vihar, Khanpur-Devoli, Ambedkar Nagar and Saket-G.

Peeved over the development, local residents of Mehrauli and Kishangargh area have also started a protest against the Delhi Metro Rail Corporation (DMRC) over the removal of four stations saying the people were waiting for years to get a metro connectivity and nearby transport facility in their area.

While the DMRC official say that such things happen while carrying out a project. "Even to construct a small road, you need permission from the concerned officials. Also, the four stations were part of the corridor and Delhi Metro wanted to construct it but at the same time route and alignment is falling near the archaeological sites where the ASI's clearance is mandatory. The ASI denied permissions for the following stations." Officials also added that the Delhi metro is working on these stations and will find alternate route to locate these stations. 

Responding to a query, an official of ASI, said, "The permission was rejected on the ground that the proposed route was passing through the protected and prohibited area ofASI monuments I.e. LalKot, Adam khan Tomb , mehrauli, the monument where the walls of Lal kot meet with kila Rai Pithoa etc." Qila Rai Pithora wall,Adam khan's Tomb, Rajon ki Bain, Gandhak ki Baoli, Walls of Rai Pithora and Lal kot meet togehter, Azim Khan's Tomb, Qutb Complex and Walls of Rai Pithora wall near Saket metro station, the ASI official added.

The Delhi Metro Rail Corporation (DMRC) has recently issued tender for the double deck construction of metro corridor on top and a six lane flyover below that metro viaduct. The Sangam Vihar to Saket section of Tughalakabad to Aerocity - G will have four elevated Metro stations - Sangam Vihar, Khanpur-Devoli, Ambedkar Nagar and Saket-G.

The total length of the Aerocity to Tughlakabad 20km with 16 stations out of which 12 are underground and four stations will be completely elevated.  The stations are Aerocity, Mahipalpur, Vasant Kunj Sector-D, Masoodpur, Kishangarh, Mehrauli, Lado Sarai, Saket, Saket G Block, Ambedkar Nagar, Khanpur, Tigri, Anandmayee Marg Junction, Tughlakabad Railway Colony and Tughlakabad.  Saket-G station will be constructed as an interchange station between Aerocity-Tughlakabad corridor and Lajpat Nagar-Saket G corridor.
