Mumbai's Ambitious Rs 848-Crore Cable-Stayed Flyover Project Takes First Steps
The Brihanmumbai Municipal Corporation (BMC) has officially launched preliminary work on a transformative infrastructure project in South Mumbai. A new cable-stayed flyover, spanning 892 meters and valued at Rs 848.63 crore, will connect the existing JJ Flyover with the forthcoming Y Bridge in Byculla. This initiative marks a significant step in Mumbai's ongoing efforts to modernize its urban transportation network and address chronic traffic issues.
Project Details and Strategic Alignment
This engineering marvel is designed to alleviate severe congestion in the Byculla and Mazgaon areas, aligning perfectly with recommendations from the Comprehensive Mobility Plan. The flyover will feature four lanes—two on each side—allowing commuters to bypass two major traffic junctions. Specifically, it will pass over critical traffic signals near Saboo Siddik Polytechnic College and Richardson and Cruddas along JJ Road in Nagpada.
The northern section of the bridge will extend 832 meters, while the southern side will measure 892 meters, including a 230-meter cable-stayed span that will become a distinctive architectural feature of Mumbai's skyline.
Timeline and Execution Framework
Following the tender award on December 12, 2025, preliminary activities have commenced. However, full-scale construction will begin only after the traffic police department issues the necessary No Objection Certificate (NOC). The project is scheduled for completion within 24 months, excluding monsoon periods, with a target finish date of 2029.
The Y-bridge redevelopment itself represents a collaborative effort between BMC and the Maharashtra Rail Infrastructure Development Corporation (MRIDC), transforming the 104-year-old structure into a modern cable-stayed bridge. The first phase of this parallel project is expected to conclude by March 2026.
Economic Impact and Administrative Perspective
While initial estimates projected costs at Rs 805 crore, the final contract settled at Rs 848.63 crore, reflecting the project's complexity and scale. Senior BMC officials emphasize the flyover's crucial role in enhancing Mumbai's traffic flow.
"This bridge will ensure seamless movement from South to North Mumbai," explained a senior BMC officer. "By eliminating waiting time at two major junctions, we anticipate significant reductions in travel duration and fuel consumption for daily commuters. Permanent ground works will commence immediately upon receiving the traffic police NOC."
The flyover will originate from the JJ Flyover, covering over 850 meters before connecting to the Y Bridge ramp near the Mumbai Fire Brigade headquarters. This strategic connection promises to transform one of Mumbai's most congested corridors into a model of efficient urban mobility.
