The flyover was built by the PWD and the Delhi Metro Rail Corporation monitors it till the end of the completion of project.
"Some 'settlement' is expected in such activities," a senior DMRC official said.
Settlement is a technical term used in the civil engineering field, and it means, level of soil going down, due to construction activities underneath it.
A senior Delhi government official, when contacted, however said, "The structure (flyover) had shown a crack one-and-a-half month ago which was fixed by the DMRC. The current sinking of ramp portion will be fixed by the Delhi Metro as it undertook subway construction underneath it."

"The subway under the flyover was made using the box-pushing technique, and will connect an entry structure with the under-construction Bhikaji Cama Metro Station of phase-III of the metro project. The work on the subway was finished on January 19," the DMRC said.
Falling on the Pink Line (Majlis Park to Shiv Vihar), the Bhikaji Cama Metro Station will have "four entry/exit points, two each on two of its sides (north and south)".
"Out of these four entry/exit points, three will be constructed new and one will be built by connecting to the existing subway under the Ring Road. After construction of this station, there will be two subways available for the public for crossing the Ring Road," it said.
