Mumbai Metropolitan Region Development Authority (MMRDA) has proposed the fully underground Dahisar-Bandra-Mankhurd metro by merging Charkop-Bandra-Mankhurd metro with the proposed Dahisar-Charkop corridor.

For the purpose, it appointed RITES to prepare the feasibility report which the latter has done and submitted to MMRDA. According to RITES, the Dahisar-Bandra-Mankhurd metro will be 40.2 km long and will have 37 underground stations. The company has proposed one major car depot at Oshiwara and one minor car depot at Mandalay, Mankhurd.
