Mumbai Metro Line 7A Faces Height Clearance Hurdle As MMRDA Holds SYSTRA Consultant Responsible For OHE Design Lapse

Mumbai Metro Line 7A is facing a height clearance obstacle, as the MMRDA has pinned the blame on its external general consultant, SYSTRA. The issue stems from inadequate provision of the additional height needed for the overhead electrification (OHE) system in the airport corridor. The Mumbai Metropolitan Region Development Authority (MMRDA) awaits a final technical report from the Airports Authority of India (AAI) regarding permissible height clearances for the airport-bound alignment.
Director Basavaraj M B of the MMRDA stated that SYSTRA failed to adequately factor in the additional height requirement during the design and planning stages. The project, which has already completed 70% of its construction, requires a 1 KM viaduct to be dismantled if the height clearance issue persists. The controversy between SYSTRA and MMRDA dates back to 2024, when SYSTRA accused the authority of harassment and challenges.
SYSTRA, which had been appointed as the general consultant in 2021 for three Mumbai Metro routes, had its contract discontinued by MMRDA in January 2025, leading to a legal battle in the Bombay High Court.
