Mumbai is set to witness a significant development in its urban infrastructure as the city inaugurates its first-ever land-based cable-stayed road overbridge (ROB) at Reay Road.
This 385-meter long structure, set to be unveiled on May 13, 2025, promises to address long-standing traffic bottlenecks and improve connectivity in one of the city’s most densely congested corridors. The overbridge, constructed by the Maharashtra Rail Infrastructure Development Corporation (MRIDC), will play a crucial role in easing the daily commute for thousands of Mumbaikars. At 7 PM on May 13, the ribbon-cutting ceremony will take place, marking a key milestone in Mumbai’s ongoing efforts to modernize its transport infrastructure. The project, which is a result of years of planning, innovation, and design, will be inaugurated by government officials overseeing infrastructure development in the state. With its strategic location, the overbridge will directly connect Mahul Road – adjacent to the Eastern Freeway – with Barrister Nath Pai Marg. This will streamline traffic flow and significantly reduce commute times by up to 30 minutes during peak hours.
The Reay Road ROB is a replacement for a 114-year-old British-era two-lane bridge, symbolising the city’s shift towards modern infrastructure that caters to its growing population and urban challenges. Designed to accommodate six traffic lanes and ample pedestrian space, the bridge is expected to ease congestion on an area that has long been a bottleneck. The importance of this project cannot be understated, as it brings a much-needed upgrade to Mumbai’s transport network while also fostering the city’s long-term goals of sustainability and efficiency. The Reay Road overbridge showcases innovative design principles that promise not only to enhance the city’s urban mobility but also reduce its environmental impact. Built at a cost of ₹273 crore, the bridge features segmental construction and the use of prefabricated components, which have been proven to reduce construction time and improve overall quality control. The cable-stayed design, supported by a central pylon and stay cables, allows for fewer piers and a reduced footprint, enabling a more streamlined construction process with less disruption to the surrounding environment.
One of the unique features of this bridge is its land-based construction. Unlike the renowned sea-facing Bandra-Worli Sea Link, the Reay Road ROB is Mumbai’s first urban cable-stayed structure built entirely on land, making it a noteworthy achievement in the city’s civil engineering landscape. This decision was driven by the desire to minimize land acquisition, reduce costs, and make use of cutting-edge engineering techniques to build a robust structure in an urban setting. The cable-stayed design also reduces the need for traditional supports and pilings, which in turn has a smaller impact on underground utilities and infrastructure. The emphasis on prefabricated components has resulted in a faster construction timeline, with the project being completed in just under two years, despite beginning in February 2022.
In terms of functionality, the Reay Road ROB promises to transform the traffic dynamics of the region. The bridge spans across the Harbour Line, enabling seamless integration with the Eastern Freeway. The elevated structure will provide vertical clearance to allow for uninterrupted movement beneath the bridge, a critical factor for the traffic-heavy Barrister Nath Pai Road. It is designed to accommodate the future growth of Mumbai’s transport network, with enough clearance to facilitate movement for trains running under the bridge and reducing congestion at multiple intersections. This initiative is a key part of Mumbai’s broader plans to modernise its road infrastructure. As the city continues to expand, improving transport efficiency is critical to reducing pollution and emissions. By easing congestion, the bridge is also expected to help alleviate the traffic-induced air quality concerns that plague urban areas. Additionally, the bridge will offer a clear, unimpeded route for the movement of goods, which is crucial for the city’s economy.
The inclusion of footpath space and LED architectural lighting makes the bridge a sustainable and aesthetically pleasing addition to the cityscape. The lighting not only ensures visibility for pedestrians and vehicles but also serves an important function in enhancing safety. Furthermore, a real-time Bridge Health Monitoring System has been installed to track the structure’s safety and ensure it remains in optimal condition throughout its lifespan. The Reay Road bridge forms a central part of the Maharashtra Rail Infrastructure Development Corporation’s (MRIDC) larger strategy to upgrade Mumbai’s ageing infrastructure. Similar projects, including other cable-stayed road overbridges at Byculla, Dadar, and Ghatkopar, are currently under construction and are expected to join the network in the near future. These bridges are part of an ambitious plan to enhance Mumbai’s transport network, reducing congestion and boosting connectivity across the city.
In a move that reflects the city’s commitment to infrastructural excellence, the bridge will be inaugurated alongside another ROB in Titwala, which spans 820 metres and offers four lanes of traffic. Built at a cost of ₹100 crore, the Titwala ROB is expected to improve east-west connectivity and ease delays in suburban rail operations by replacing multiple level crossings. Together, these initiatives highlight a new wave of infrastructure development that aims to improve urban mobility, boost economic growth, and contribute to a cleaner, more sustainable environment for the city’s residents. While the Reay Road ROB is undeniably an engineering marvel, it also plays an essential role in supporting Mumbai’s broader sustainability agenda. In line with the city’s commitment to becoming more environmentally friendly, this bridge is designed to reduce traffic congestion, which will subsequently lower carbon emissions. With the growing emphasis on clean air and zero-emission transport systems, initiatives like these are crucial for improving the quality of life for urban dwellers.
Furthermore, the bridge exemplifies the integration of new-age technologies that blend sustainability with cutting-edge design. From its energy-efficient LED lighting to the advanced monitoring systems, the structure represents the future of urban infrastructure. The increased efficiency in traffic movement will contribute to less fuel consumption, benefiting both the environment and the city’s residents. The Reay Road cable-stayed road overbridge marks a new chapter in Mumbai’s infrastructural evolution. As the city continues to grow and adapt to the demands of urbanisation, projects like these provide much-needed relief from congestion while contributing to long-term sustainability goals. By offering improved connectivity, enhanced safety, and environmental benefits, this landmark infrastructure project exemplifies the future of Mumbai’s transport network. The successful completion of this bridge sets a precedent for similar initiatives that can serve as models for urban development across India.
