Getting inspiration from the Nagpur Metro model, the Mumbai Metropolitan Region Development Authority is now planning to build a double-decker corridor on the stretch of Kashimira road (Metro Line 9 Dahisar – Bhayandar) by 2022. The new model will provide a double-decker viaduct, where flyovers for automobiles will be built on the first level and the metro line will run on the second level of the route. The corridor will have a multi-layered transport facility with the metro line on the upper deck and a flyover on the lower deck above the existing road.
The Mumbai Metro-9 will provide interconnectivity among the existing Western Express Highway, Western Railway, Mumbai Metro Line 2A (Dahisar – DN Nagar) and Metro Line-7 (Andheri East to Dahisar East).
