Imagine a basketball court, a museum, a joggers’ track and an amphitheatre — all below one of Mumbai’s most congested flyovers. At a time when preserving an open space in the city is becoming next to impossible, the residents of Matunga and Dadar have come up with an innovative proposal to keep the open space below the Ambedkar Road flyover free from encroachments and illegally parked vehicles. Last week, they submitted their proposal to the Mumbai Metropolitan Regional Development Authority (MMRDA) elaborating the usage of the open space beneath the flyover.
