The Metro corridor from Western Express Highway to the city airport, which will be built to connect Dahisar-Andheri Metro-7 and Colaba-Bandra-Seepz Metro-3, may be underground. The link, which will be an extension to Metro-7, is aimed at providing the connectivity between the southern and northern parts of the city via the airport.
The Mumbai Metropolitan Region Development Authority (MMRDA) has undertaken development of the 170-km Metro network in the region.
While the state government is keen on constructing elevated corridors for all new Metro projects, the link between Metro-3 and Metro-7 may be underground for a variety of reasons. First, the elevated corridor is not possible because of lack of space. Moreover, it has to be connected with Metro-3, which is fully underground.
“We have started carrying out studies to find what kind of corridor should be constructed. The tunnel corridor seems to be the most viable option,” said a senior MMRDA official.
The underground link will be about 3km in length, which might connect all three underground stations of Metro-3 to the airport. This arrangement will help commuters from any part of Mumbai, travelling on any other Metro line, reach the airport smoothly.
A few months ago, the MMRDA took the decision to integrate Metro-7 with Dahisar-Bandra-Mankhurd Metro-2, which will help in connecting areas flanked by the highway with each other.
The Japan International Cooperation Agency is funding Metro-3, while the Asian Development Bank (ADB), which has already decided to fund Metro 2A and Metro 7, has shown interest in providing financial assistance to Metro-2B and Wadala-Thane-Kasarvadavali Metro-4.
