The east-west shortcut that Mumbai commuters have been waiting for could finally be back in business. The Sion Railway Overbridge, which has been shut for reconstruction, is expected to reopen this weekend. However, the Brihanmumbai Municipal Corporation (BMC) is yet to confirm an opening date, with the bridge reportedly awaiting an official inauguration and final clearance from the traffic police.
The reopening would restore a crucial link between Sion East and Sion West, easing the detours that commuters have had to navigate since the old bridge was closed. For motorists travelling through one of Mumbai’s busy transport hubs, the new bridge could mean a more direct route across the railway tracks. Pedestrians are also expected to benefit from improved access to Sion Railway Station.
According to The Indian Express, the final stages of work were underway as of Wednesday, October 14, with road markings, traffic signals and beams among the remaining finishing touches. Load testing has reportedly been completed, leaving traffic police clearance as one of the outstanding requirements before the bridge can open to the public.
Why was the Sion Railway Overbridge closed?
The original Sion Railway Overbridge dated back to 1912. A structural audit conducted in 2019 flagged concerns about its condition, prompting the decision to replace the ageing structure. Its closure cut off a well-used east-west connection, forcing motorists to take alternative routes and adding to the inconvenience of travelling through Sion.
The reconstruction also forms part of Central Railway’s broader infrastructure work on the fifth and sixth railway lines between Chhatrapati Shivaji Maharaj Terminus (CSMT) and Kurla. The bridge had to be rebuilt to accommodate these railway upgrades, making the project an important part of the wider effort to improve rail capacity along this stretch.
What are the key upgrades on the new Sion bridge?
The new bridge has been jointly constructed by the BMC and Central Railway at a reported cost of around ₹60 crore. It is also larger than the original structure, with a length of 61 metres compared with the old bridge’s 40 metres.
Here’s what commuters can expect from the rebuilt bridge:
-
Four vehicular lanes: The expanded structure is designed to accommodate road traffic across the railway corridor.
-
A dedicated footpath: Pedestrians will have a designated walking route, with access connecting to Sion Railway Station.
-
An underpass: The project also includes an underpass expected to improve movement for pedestrians and vehicles in the area.
-
A more direct east-west connection: Once opened, the bridge will restore a familiar route between Sion East and Sion West, reducing the need for some of the diversions commuters have relied on during the closure.
Together, these changes are intended to improve traffic movement around Sion and make the approach to the railway station more accessible for pedestrians and motorists.
So, when will the Sion bridge reopen?
An October 15 deadline had been set for the remaining work, and the latest reports suggest that construction is nearing completion. However, the anticipated weekend reopening is not yet confirmed by the BMC. The bridge must still receive the necessary traffic police clearance, while the reported inauguration is another outstanding step.
There is also a longer timeline to consider. The tender schedule reportedly lists February 2027 as the completion date for the Sion bridge project, despite the expectation that the structure could open to traffic sooner. The distinction between the anticipated opening and the project’s scheduled completion makes an official confirmation particularly important.
For now, Mumbai commuters may be close to getting their east-west shortcut back, but it is worth keeping alternative routes in mind until the BMC announces the reopening and confirms that traffic can use the bridge.
