Mumbai marked a significant milestone in its urban infrastructure development with the inauguration of the region’s first double-decker flyover in the western suburbs of Mira-Bhayander.
This state-of-the-art structure, which was opened for vehicular traffic recently, is set to revolutionise the commuting experience for residents by integrating a double-decker Metro viaduct with a flyover on Metro Line-9. Spanning approximately 1 kilometre in length and elevated 5.5 metres above the existing road level, the double-decker flyover aims to alleviate traffic congestion at key junctions including Pleasant Park, Hatkesh, and Silver Park. Designed to handle heavy traffic, including multi-axle vehicles, the flyover meets stringent standards and is equipped with modern furniture, signage, and lighting, all inspired by the aesthetic of the Metro Red Line.
The dual-layered infrastructure is expected to deliver substantial benefits, including a reduction in travel time by 8 to 10 minutes and smoother traffic flow, which in turn will decrease fuel consumption, leading to cost savings for drivers. By minimising vehicle idling, the flyover is also anticipated to reduce greenhouse gas emissions and other pollutants, thereby contributing to Mumbai’s environmental sustainability goals. Furthermore, the elevation of the roadway helps to diminish noise pollution and preserve vital green spaces, which are crucial for maintaining the urban ecosystem.
The Mumbai Metropolitan Region Development Authority (MMRDA) faced several challenges during the construction phase, notably the relocation of approximately 3 kilometres of the main double-circuit Dahanu-Versova power generation line. This line was elevated to 75 metres above ground level, making it the second-tallest of its kind in Maharashtra, ensuring uninterrupted Metro operations on the upper deck of the flyover. The project leveraged I-girder (flyover pier cap) precast technology to expedite construction and maintain high-quality standards. Completed within a span of two years, the erection of U-girders was strategically conducted during daylight hours without disrupting traffic flow.
This was achieved through the innovative use of Tyre Straddle Carrier technology, which allows vehicles to pass through its arms, unlike conventional cranes that typically block traffic. This approach was crucial as the route sees an average of 800 vehicles per hour. Maharashtra Chief Minister Eknath Shinde, during the inauguration, highlighted the significance of the project, stating, “The launch of the first double-decker flyover in the Mumbai Metropolitan Region is not just a milestone for Mumbai but a key step in Maharashtra’s development. This initiative will alleviate traffic woes, save time and fuel for commuters, and enhance the overall coherence of traffic in the city.”
An MMRDA official further noted that the flyover’s design seamlessly integrates with Metro pillars, allowing Metro trains to operate on the upper level while vehicles commute below on the flyover. At ground level, road traffic flows without hindrance, creating a modern, multi-layered solution to meet Mumbai’s evolving transportation needs. The project is poised to significantly reduce traffic congestion and provide a faster, safer, and more convenient travel experience, catering to the city’s growing demands and future urban development.
