The Mumbai Metropolitan Region Development Authority (MMRDA) is currently planning a mega road network across the  Mumbai Metropolitan Region (MMR). This network will span from Vadodara, Gujarat border up North to Alibaug in the Konkan belt of Maharashtra down South and towards Navi Mumbai/Thane.

Reporting on the network, The Indian Express accessed the masterplan prepared by the MMRDA. This vast network of roads, flyovers, bridges, coastal roads and underwater tunnels aim at decongesting Mumbai by 2029.

The MMRDA has authorised the construction of an additional 90.18 kilometers of road network, with an estimated cost of Rs 58,517 crore. This project will connect the Outer Ring Roads to the inner Ring Roads, facilitating uninterrupted travel between North and South Mumbai and enhancing East-West connectivity, IE reported.

The inner Ring Roads are designed to accommodate the rapid urbanisation of Mumbai and Thane. However, the initiative extends beyond just road construction, the total estimated cost for all infrastructure projects in the MMR – including metro systems, new roads, bridges, flyovers, and slum development – amounts to Rs 3 lakh crore.

To build the Ring Roads and the other necessary connecting roads, several development authorities such as MMRDA, Brihanmumbai Municipal Corporation (BMC) and the Maharashtra State Road Development Corporation (MSRDC) will come together. What makes these Ring Roads significant is their emphasis on enhancing East-West connectivity.

Mumbai Metropolitan Region: Ring Roads network

First Ring Road – Nariman Point-Coastal Road-Worli Sewri Connector-Eastern Freeway-Orange Gate Tunnel-Nariman Point

The first Ring Road starts at Nariman Point on the Mumbai Coastal Road, moving onto the the Bandra-Worli Sea Link at the Worli Junction. From that point, a right turn leads to the Sewri-Worli Connector, which connects to the southern end of the Atal Setu. The route extends to the proposed Orange Gate Tunnel and ultimately loops back to Nariman Point via the Coastal Road.
