An image showing what appeared to be a weakened section of a concrete parapet wall on the under-construction Mumbai Metro Line 4 near Anand Nagar on Ghodbunder Highway circulated widely on Wednesday evening,
triggering concern among residents and commuters. The visual prompted fears of a repeat of the LBS Marg Mulund incident earlier this year, raising questions about construction safety.
According to a report in The Times Of India, following the alert, the Thane regional disaster management cell informed Metro authorities, who quickly reached the site and reviewed the structure.
Officials from the Mumbai Metropolitan Region Development Authority (MMRDA) clarified that the portion in question had already been secured. They explained that the apparent gap visible from the outside was only superficial and did not impact the structural performance of the parapet.
According to the officials, the supporting stitch work for the parapet has been completed and the structure is safe.
Breakthrough In Laxmi Nagar Station Land Acquisition
In a key development for Metro Line 4, the MMRDA has acquired a 16,762 sqm land parcel for the long-delayed Laxmi Nagar station in Vikhroli, marking the final pending station on the corridor after a six-year delay.
According to a report in The Indian Express, all other stations along the 32.32-km route have already been constructed. The newly acquired site will be used to build the station, an adjoining viaduct, and an access road. While construction has yet to begin, preliminary surveys are currently underway.
Officials added that land acquisition for the corridor is almost complete, with only a small 200 sqm plot in Bhandup still pending for a high-tension tower, expected to be resolved within a month.

Mumbai Metro Expansion Set To Accelerate In 2026
After the launch of the Aqua Line in 2025, Mumbai’s Metro network is poised for further expansion in 2026. Multiple corridors across the Mumbai Metropolitan Region are expected to become operational, strengthening alternatives to the suburban railway system.
According to a report in Daily Hunt, authorities are planning to open sections of four Metro lines along with one extension this year, with two launches likely in January. Meanwhile, major infrastructure works such as the Thane-Borivali Twin Tunnel and parts of the Eastern Freeway are expected to be completed at a later stage.
Metro Lines 4 and 4A, forming a crucial Mumbai-Thane link, are expected to open in phases during 2026.
- Nearly two-thirds of the alignment could be operational this year
- Initial 10.5-km stretch from Cadbury Junction to Gaimukh expected by March
- Includes Line 4A, a 2.7-km spur between Kasarvadavali and Gaimukh
- A further 10-km extension to Gandhi Nagar in Vikhroli is targeted within six months
