India’s longest sea bridge, Atal Setu, has officially opened its lanes, marking a significant milestone in the nation’s infrastructure landscape. Inaugurated by Prime Minister Narendra Modi on January 12 in Mumbai, the bridge not only stands as a symbol of connectivity but also showcases cutting-edge technologies that have contributed to its construction. Ranked as the 12th longest sea bridge globally, Atal Setu connects South Mumbai to Navi Mumbai, drastically reducing travel time and setting new benchmarks in engineering excellence. Let’s delve into the top seven advanced technologies incorporated into the construction of Atal Setu.
1. Real-time Traffic Information: Enhancing Commuter Experience
Atal Setu employs real-time traffic information technology, providing drivers with up-to-the-minute details about traffic conditions and any accidents on the bridge and its surrounding roads. This ensures a smoother commuting experience and timely responses to potential disruptions.
2. Advanced Traffic Management System: A Smart Solution for Safety
The bridge incorporates an advanced traffic management system capable of detecting fog, low visibility, and vehicles exceeding speed limits. This technology enhances safety measures, contributing to accident prevention and efficient traffic flow.
3. Reverse Circulation Rigs: Mitigating Environmental Impact
Specialized reverse circulation rigs play a crucial role in reducing sound and vibrations on Atal Setu. This eco-friendly approach protects marine life in the surrounding waters, showcasing a commitment to minimizing the environmental impact of the bridge’s construction.
4. Eco-friendly Lighting: Illuminating Responsibly
The lighting system on Atal Setu is designed to be eco-friendly, ensuring that it does not disturb the aquatic environment. Incorporating several innovative lighting technologies, the bridge sets new standards for responsible infrastructure development in India.
5. River Circulation Rings: Safeguarding Marine Life
Utilizing river circulation rings, Atal Setu minimizes sound and vibrations, prioritizing the protection of marine life around the bridge. This technology demonstrates a thoughtful approach to balancing infrastructural needs with environmental conservation.
6. Open Road Tolling System: Streamlining Traffic Flow
The Atal Setu features an open road tolling system that leverages electronic toll collection (ETC) technology. This modern tolling approach automatically collects tolls from vehicles without requiring them to stop, reducing traffic congestion at toll booths and ensuring a seamless travel experience.
7. Orthotropic Steel Deck: Structural Innovation
A pioneering technology in India, the orthotropic steel deck used in Atal Setu provides extensive spans, enhancing the bridge’s structural integrity. This innovation contributes to the overall durability and longevity of the sea bridge.
Prime Minister Modi laid the foundation stone for Atal Setu in December 2016, and the completion of this six-lane, 21.8-kilometer bridge underscores a total investment exceeding Rs 17,840 crore. Apart from setting new records in length and connectivity, Atal Setu positions India as a global leader in adopting advanced technologies for sustainable and innovative infrastructure development.
