According to MMRDA Metropolitan Commissioner Dr Sanjay Mukherjee, the corridor is expected to reduce travel time by 40 per cent to 50 per cent compared with road journeys. The proposed interchanges and feeder buses are intended to make travel between Kalyan-Dombivli, Kalyan Phata, Taloja and Navi Mumbai more convenient.
The project is also expected to ease congestion on major roads and national highways by encouraging commuters to use public transport. A shift away from private vehicles could help reduce transport-related carbon dioxide emissions.
Who Will Implement The Project?
The MMRDA will implement Metro Line 12A and has been appointed the special planning authority for the metro corridor and integrated flyovers. The Cabinet Infrastructure Committee has also approved the transfer of identified government land within the project’s influence area to the authority for project development and resource mobilisation.
