Mumbai: MahaRail Fast-Tracks City’s First Double-Decker Road Over Bridge at Elphinstone

The Maharashtra Rail Infrastructure Development Corporation Limited (MahaRail) today announced that the transformative Elphinstone Double-Decker Road Over Bridge (ROB) project is on track for completion by September 2026. This landmark infrastructure, part of the Sewri-Worli Elevated Corridor, is currently in a significant phase as demolition of the existing 112-year-old British-era structure proceeds in full swing.

The project, entrusted to MahaRail by the Mumbai Metropolitan Region Development Authority (MMRDA), involves a complex engineering feat i.e. the dismantling of the old bridge using two 800MT cranes. This delicate operation is being executed over running railway tracks without disrupting the suburban train services of both the Western and Central Railway lines.

Key Features of the Project:
• Double-Decker Design: This ROB will simultaneously cross both the Central Railway and Western Railway Lines, a rare and complex engineering feat.

• Total Length (Railway Span): 132 meters, ensuring seamless movement over
railway tracks.

• Lane Configuration: o Lower Deck: 2+2 lanes with a footpath, maintaining east-west connectivity for local traffic. o Upper Deck: 2+2 lanes (without footpath) for Sewri–Worli Elevated Corridor, providing a direct link to the Atal Setu (Mumbai Trans Harbour Link) for improved regional connectivity.

• Superstructure Type: Open Web Girder, a robust and durable design suited for Railway bridge construction.

• Estimated Cost: Rs 167.35 crore. With this redevelopment, MahaRail aims to preserve the legacy of the original bridge while addressing current and future transportation challenges, ensuring enhanced connectivity, efficiency, and safety for Mumbai’s residents.
