Sion Railway Over Bridge Work Enters Final Stretch, Set to Open by September 30
Reconstruction of the Sion Railway Over Bridge is in its final phase, with work scheduled for completion by September 30, 2026. Central Railway has finished deck-slab concreting across both new girders, while crews carry out work on crash barriers and concrete wearing coats. Simultaneously, the Brihanmumbai Municipal Corporation is fast-tracking the rebuilding of the LBS Marg–Sant Rohidas Marg approach road in Dharavi.
The 112-year-old overbridge was shut down on August 1, 2024, after being declared unsafe, cutting off a key east-west transit corridor. Demolition of the aged structure was executed in two phases to reduce hardship for residents, beginning with the removal of the northern section while the southern portion remained accessible to pedestrians.
A senior official from the BMC Bridges Department confirmed that deck-slab concreting on both new girders is complete, while workers finish the crash barriers and concrete wearing coat. The official noted that the new pedestrian bridge is operational and the demolition of the remaining section of the old overbridge has been completed.
Work on linked connectivity points has also reached significant milestones over recent months. The new LBS Marg subway opened to the public on February 20, 2026, followed by the rebuilt Sant Rohidas Marg subway on July 14, 2026. Both facilities are operational as reconstruction on the approach roads continues to progress.
Mumbai Mayor Ritu Tawde has instructed authorities to maintain high standards for finishing works on the structure. The mayor also directed officials to explore planting vertical gardens and greenery along the central median and on both sides of the bridge.
The two-year closure forced thousands of commuters onto detour routes, creating severe traffic congestion across neighbouring areas. Rebuilding the structure is part of the Mumbai Urban Transport Project (MUTP-2), designed to facilitate Central Railway's fifth and sixth lines between Chhatrapati Shivaji Maharaj Terminus and Kurla. Under the arrangement, the railway authority is reconstructing the main span within its limits while the civic body strengthens the approach roads. Funded by the Railways, the overall project cost escalated from Rs 42.8 crore to nearly Rs 50 crore following the inclusion of steel girders and approach road works.
