Hello Mumbai City Desk
MMRDA Achieves Major Engineering Milestone on Mumbai Metro Line 6: Completes 42m Steel Span Over Active Western Railway Corridor
42meter, 168.96-Tonne Steel Span Over Live Railway Marks Turning Point for Metro Line 6
Mumbai, April 26, 2026:
The Mumbai Metropolitan Region Development Authority has achieved a significant engineering milestone in the execution of the Mumbai Metro Line 6 spaning approximately 14.5 kilometres by successfully completing one of the most complex construction activities along the corridor construction of a critical pier within an active railway zone and erection of the steel composite span over the tracks of Western Railway near Jogeshwari.
Key Features:
* Length: 14.5 km (Fully elevated)
* Stations: 13 Nos.
* Line Color: Pink Line
* Depot: Kanjurmarg (15.2 Ha.)
* Double Decker flyover at JVLR Road along Metro Line 6
•Curent Status: 87.7% civil work completed.
*Complex Substructure Execution in Active Railway Zone*
The milestone began with the construction of Pier P124, uniquely located between the up-through and down-through railway tracks in one of Mumbai’s busiest suburban rail corridors..
Execution of substructure works in this confined and high-risk zone required exceptional planning, coordination, and adherence to stringent safety protocols. The entire substructure activity including foundation works and pier construction up to pier cap level was carried out strictly in accordance with all railway safety standards and approved norms.
Despite continuous train movement on both sides, the work was executed without any disruption to railway operations. This phase was particularly critical due to:
• Limited working windows during night hours
• Continuous train movement on adjacent tracks
• Requirement for controlled execution and close monitoring
• Strict compliance with railway safety protocols
*Erection of 42m Steel Composite Girder Span*
Following the successful completion of Pier P124, MMRDA erected the first steel composite girder span between Pier P123 and P124.
The span:
• Measures 42 metres in length
• Weighs approximately 168.96 metric tonnes
• Comprises multiple main girders, cross girders, and bracing elements forming a composite steel girder system
The erection was carried out within a stipulated railway block of approximately 10 hours, demonstrating high levels of planning and execution efficiency.
*High-Precision Crane Operation in Constrained Conditions*
The operation involved the use of 500-ton and 600-ton capacity hydraulic cranes, deployed in tandem for synchronized lifting. Due to the constrained site conditions, the cranes were strategically positioned between active railway tracks, making this a highly complex and precision-driven activity.
The span was successfully erected at an elevation of approximately 10–12 metres above railway level, ensuring all mandated safety clearances.
The entire operation was completed:
• Within the scheduled railway block period
• With meticulous planning and coordination
• In full compliance with safety standards
• Without any impact on railway operations beyond the approved block
This achievement marks a major breakthrough in overcoming one of the most challenging railway crossing sections of Metro Line 6. The successful execution was made possible with strong coordination and support from Western Railway.
*Interchange Connectivity:*
* Integrated with Metro Line 2A at Adarsh Nagar
* Metro Line 7 at JVLR
* Metro Line 3 at SEEPZ area
* Metro Line 4 at Kanjurmarg (W)
* Suburban Railways at Jogeshwari and Kanjurmarg respectively
Enhancing Mumbai’s East–West Connectivity and Key Benefits
Mumbai Metro Line 6, connecting Swami Samarth Nagar (Lokhandwala) to Vikhroli, is a key infrastructure project aimed at improving east–west connectivity across the city. Once operational, the corridor will:
• Significantly reduce travel time for daily commuters travelling across the city
• Help decongest major roads, particularly key corridors such as the Jogeshwari–Vikhroli Link Road (JVLR)
• Enhance connectivity by integrating with existing and upcoming metro lines as well as suburban rail networks
• Provide a safe, reliable, and comfortable mode of transport for thousands of passengers
• Contribute to environmental sustainability by encouraging a shift from private vehicles to public transport, thereby reducing traffic congestion and emissions
This milestone underscores MMRDA’s capability to execute highly complex infrastructure projects in dense urban environments with precision, safety, and efficiency. The authority continues to demonstrate engineering excellence while adhering to the highest standards of safety and coordination.
Highlighting the significance of this milestone, Dr Sanjay Mukherjee ,IAS, Metropolitan Commissioner MMRDA Said:
*Metro Line 6 has been a long-awaited project for Mumbaikars, and we are conscious of the expectations associated with it. This milestone marks meaningful progress in one of the most challenging sections of the corridor and reflects our focused efforts to move the project forward with speed and precision. At this stage, we are also actively evaluating multiple options to operationalise the corridor in a phased manner, so that commuters can start benefiting from the project at the earliest. Our priority remains to deliver a reliable and efficient east–west connectivity solution for the city.”*
