The Phase 1 of Mumbai Metro corridors 2A and 7 between Dahanukarwadi and Aarey, a stretch of 20 km in the western suburbs, has received provisional certification from the Research, Design and Standard Organisation (RDSO), a pre-requisite to begin commercial operations. The Mumbai Metropolitan Regional Development Authority (MMRDA) is constructing a 35-km stretch of two elevated Metro corridors – Line 2A between Dahisar and D N Nagar and Line 7 between Dahisar East and Andheri East. The commercial operation of both the lines is planned in two phases.
Currently, the MMRDA is testing the lines partially between Aarey and Dahisar East (Line 7) and Dahisar (West) and Dahanukarwadi (Line 2A). As part of Phase 1 of the project, 2A and 7 corridors will cover 18 stations.
