The 40km 36-station Line 2 will run completely underground from Dahisar in the north to Charkop and Bandra terminating at Mankhurd in the east of the city. The total budget for the project is estimated to be around Rs 256bn ($US 4.1bn).
Line 4 will be 32km long with 24 underground and six elevated stations, and will link Wadala with Ghatkopar and Kasarvadavali in Thane on the northern side of Mumbai. The project is expected to cost around Rs 191bn.
Half of the funding for the two lines is expected to come from international finance agencies, with the Indian government, the state of Maharashtra and MMRDA providing 20%. The remaining 30% will be financed through equity and debt. Both lines are due to open in 2020-21.
Earlier this week the Maharashtra state government terminated a concession agreement with Reliance Infrastructure subsidiary Mumbai Metro Transport Private Ltd (MMTPL) for the construction of the Mankhurd – Charkop section of Line 2 due to environmental and administrative issues. This project will now be retendered and the contract will include the northern extension from Charkop to Dahisar.
The city's first metro line, which runs east-west from Versova to Ghatkopar was inaugurated in June and a foundation stone was laid in August for the 33km north-south Line 3 from Santa Cruz Electronic Export Processing Zone to Bandra and Colaba, which is expected to open in 2021.
