With an intention to provide alternate connectivity to Mumbaikars, the plan to construct the Mumbai Metro took shape in 2006, when the foundation stone for phase-I of the metro project was laid. However, operational and policy delays resulted in delays to the project and as of June 2021, only one metro route has been commissioned. These massive delays have also resulted in massive escalation in overall expenses to Rs 82,172 crores.

Mumbai Metro network and corridors

The Mumbai Metro network is being implemented by the Mumbai Metropolitan Region Development Authority (MMRDA) as it is being expanded beyond the Mumbai region. At present, only one metro line is operational while eight are under-construction and five routes have been approved. The first line began operation in June 2014, while two other lines are expected to become operational by July 2021. There are 14 corridors on Mumbai Metro network, plus two extension lines:
