The Mumbai Metropolitan Region Development Authority (MMRDA) has assigned the Maharashtra Rail Infrastructure Development Corporation (MahaRail) to carry out the construction. The bridge will incorporate a 132-meter railway span using an Open Web Girder structure, known for its strength and durability in railway bridge construction.

The lower deck of the ROB will have a 2+2 lane configuration with a footpath, ensuring smooth east-west movement for local traffic. The upper deck, also with a 2+2 lane design but without a footpath, will integrate with the Sewri–Worli Elevated Corridor, offering direct connectivity to the Atal Setu, or Mumbai Trans Harbour Link (MTHL). This strategic design aims to enhance both intra-city and regional connectivity.

Constructed in 1913 during the British era, the existing Elphinstone Road Over Bridge has been a crucial transport link for over 125 years, accommodating both vehicles and pedestrians across the railway lines. However, increasing urbanization has led to severe congestion and safety concerns, necessitating its replacement with a modern structure.

The project involves dismantling the old ROB using two 800MT cranes, a highly challenging operation conducted over active railway tracks. To prevent disruptions to suburban train services on both the Western and Central Railways, meticulous planning and execution are essential. The new ROB is expected to be completed within a year after securing all necessary approvals, ensuring enhanced safety and efficiency for Mumbai’s commuters.
