The construction of the 33.5km underground metro line between Colaba–Bandra–SEEPZ will result in 1,74,632 square meters of land (government and private plots, including open spaces) being used for the corridor permanently. Additionally 19,033 sq mts will be used temporarily, only during the construction phase.
On February 13, top officials from the Mumbai Metropolitan Region Development Authority and the Brihanmumbai Municipal Corporation had held a meeting with their team to clear issues that may arise in future and even for mutual cooperation during the construction phase.
In all, 27 stations are proposed along the route. As per the Detailed Project Report prepared by engineering consultancy firm RITES and submitted back in November 2011 to the MMRDA, a total of 47,226 sq mts will be taken away permanently to have entry, exit, escalator, water tank, fuel tank, ventilation shaft, among other things.
Above that, later the development authority zeroed in on 30 acres of Aarey Milk Colony to have a car depot for the third metro corridor.
Additionally, there will be a need to have sub-station at regular intervals to keep the metro trains moving, for which three locations have been mentioned in the report — Cuffe Parade, Worli and Bandra. In all 6,000 sq mts will be permanently used.
The authorities intend to build five of the stations — Cuffe Parade, Bandra, Kalina, MIDC and SEEPZ stations — using the cut-and-cover method of construction. As the term suggests, the ground will be dug and entire station will be constructed. In the end, the top will be covered so that usual activities can be carried out at grade level.
A look of the report states that mangroves at Bandra, gardens, playgrounds, religious shrines including a portion of Parsi Temple at Kalbadevi, private residential and commercial spaces, fuel stations, race course, open area inside the university's campus, police colony at MIDC, etc will have to make way to resolve commuting woes for Mumbaikars.
An underground metro rail is always a preferred option as compared to elevated is a metropolis like Mumbai, where there are space constraints. The cost for this metro corridor has been estimated at Rs23,136 crore, and part of the funding will be through a loan from Japanese International Co-operation Agency.
An MMRDA official informed, "The total area mentioned in the report prepared by RITES mentions the larger picture. There is a possibility of variations in the land needed as another study is underway for the project."
