Mumbai Metro Line 7A Faces Airport Height Clearance Hurdle
Mumbai is building a metro line to connect Andheri East with the airport.
The trains will use overhead electrical equipment called OHE.
MMRDA says the project consultant did not properly include the extra height needed for this equipment.
The metro must also stay within height limits set because it is near an airport.
MMRDA is waiting for a final technical report from the Airports Authority of India.
After receiving it, MMRDA will decide whether changes are needed.
The consultant, SYSTRA, has previously accused some MMRDA officials of asking for improper payments and causing project delays.
SYSTRA also challenged MMRDA’s decision to end its contract, and the Bombay High Court criticized that decision as unfair and unreasonable.
MMRDA has held the SYSTRA-CEG-SMCIPL consortium responsible for failing to account adequately for OHE height requirements.
The authority is awaiting the Airports Authority of India’s final report on permissible clearances for the airport corridor.
Metro Line 7A is a 3.4-kilometre extension connecting Andheri East with Chhatrapati Shivaji Maharaj International Airport.
MMRDA said it will assess the technical impact and decide on corrective measures after receiving the AAI report.
The development follows a dispute over MMRDA’s discontinuation of SYSTRA’s consultancy services in January 2025.
