The Mumbai Trans Harbour Link (MTHL), commonly referred to as the Atal Setu, is India’s longest sea bridge. It is 21.8 km in length, of which 16.5 km are over the water and the remaining 5.5 km are on land.
wonder of engineering
With features that guarantee commuter safety and efficiency, the Atal Setu is a masterpiece of contemporary engineering. The entire length has a ventilation system and an emergency escape route, ready to handle any unforeseen emergencies. Additionally, the bridge is built to support two-way traffic movement.

The bridge bears the name of Atal Bihari Vajpayee, a former Indian prime minister renowned for his foresight and guidance. ‘Atal Bihari Vajpayee Sewri-Nhava Sheva Atal Setu’ is the official name. The much-awaited Atal Setu was formally opened by Prime Minister Narendra Modi on January 12, 2024. This was a major turning point in the development of India’s infrastructure and provided comfort to people whose trip plans were hampered by bad weather or heavy traffic.
environmentally friendly
Environmental sustainability was given a priority throughout the Atal Setu’s development. The accomplishments of the initiative were also recognised with a certificate of appreciation from the prestigious environmental institution, the Bombay Natural History Society. In order to reduce noise and vibrations that can endanger marine life, precautions were made.
less distance to go
Faster access to Mumbai International Airport and Navi Mumbai International Airport is now possible thanks to the Atal Setu. It also shortens the travel time from Mumbai to Pune, Goa, and South India. Furthermore, it has improved the link between.
Mumbai Port and Jawaharlal Nehru Port. The Mumbai Metropolitan Area is anticipated to have substantial economic growth as a result of the Atal Setu. The bridge will help with trade, business, and general economic activity since it will shorten travel times and provide communication between important locations.
Atal Setu, officially known as the Mumbai Trans Harbour Link (MTHL), stands as India’s longest sea bridge, connecting Mumbai to Navi Mumbai. Here are five notable facts about this engineering marvel:
- Record-Breaking Length: Spanning a total length of 21.8 kilometers, Atal Setu surpasses all other sea bridges in India. Approximately 16.5 kilometers of the bridge extends over the sea, while the remaining 5.5 kilometers traverse land.
- Six-Lane Configuration: The bridge features a six-lane design, with three lanes allocated for each direction. This configuration is designed to accommodate up to 70,000 vehicles daily, significantly easing traffic congestion between Mumbai and Navi Mumbai.
- Advanced Construction Techniques: Atal Setu incorporates Orthotropic Steel Deck (OSD) spans ranging from 65 meters to 180 meters, marking a first in Indian bridge construction. This technique enhances the bridge’s strength and durability.
- Significant Investment: The construction of Atal Setu required an investment of approximately ₹17,840 crore (US$2.2 billion). This substantial funding underscores the project’s importance in enhancing regional connectivity and supporting economic growth.
- Inauguration and Accessibility: Construction of the bridge commenced in April 2018 and concluded in December 2023. The bridge was officially inaugurated by Prime Minister Narendra Modi on January 12, 2024, and opened to the public the following day, providing a direct and efficient route between Mumbai and Navi Mumbai.
Atal Setu not only exemplifies India’s engineering capabilities but also plays a pivotal role in improving transportation infrastructure, fostering economic development, and enhancing the daily commute for thousands of residents in the Mumbai Metropolitan Region.
