Steel Used in making Atal Setu can help build 4 Howrah Bridges, 17 Eiffel Towers- Here is all you need to know!

The Bridge that will Stand for 100 Years

The Mumbai Trans Harbour Link (MTHL), christened the Atal Bihari Vajpayee Sewri to Nhava Sheva Atal Setu, stands as an architectural triumph, connecting Mumbai to Navi Mumbai. This six-lane sea bridge, with a staggering total length of 22 km, is not just a bridge; it’s a testament to advanced technology, meticulous planning, and a commitment to revolutionizing urban connectivity.

Engineering Marvel and Construction Details:

The Bridge Structure:
Constructed with cutting-edge Japanese technology, the MTHL comprises 16.5 km of sea bridge and 5.5 km of elevated road on land. Spanning from Sewri in South Mumbai to Chirle near Nhava Sheva in Navi Mumbai, the bridge plays a pivotal role in enhancing connectivity between Mumbai, Navi Mumbai, Pune, Goa, and South India.

Materials Used:
The sheer magnitude of the project is awe-inspiring. The structural steel used in the Atal Setu alone amounts to approximately 1.2 lakh tonnes, equivalent to supporting the erection of four Howrah Bridges. The project utilizes a staggering 8,30,000 cubic meters of concrete, six times more than required for the iconic Statue of Unity, and 17 times the quantity used in the Eiffel Tower for reinforced steel.

Investment and Workforce:
The colossal endeavor demands a total investment of about Rs 20,000 crore. Over 15,000 skilled laborers and more than 1,500 engineers have devoted their expertise to bring this project to fruition.

Technological Advancements and Features:

MTHL’s Advanced Technology:
The MTHL is not just a physical link; it’s a marvel of technological integration. With a designed commuting speed of 100 km/h and a daily capacity of 70,000 vehicles, it employs a unique toll management system featuring Electronic Toll Collection (ETC) through Open Barrier Tolling methodology.

Surveillance and Safety Systems:
Comprehensive Surveillance Systems, high-definition cameras, Speed Violation Detection System, and Video Incident Detection System contribute to road safety. Emergency Calling Boxes provide direct communication links to emergency services. Variable Message Display systems relay real-time information to commuters. The Advanced Traffic Management System (ATMS) enables real-time monitoring and management.

Environmental Considerations and Growth Impacts:

Ecological Preservation:
The MTHL project is designed with a keen eye on ecological preservation, addressing concerns like the protection of the Flamingo habitat. It aligns with environmental goals by aiming to reduce fuel consumption and greenhouse gas emissions.

Catalyst for Progress:
The MTHL’s impact extends beyond infrastructure. Termed a “game changer,” it is poised to accelerate growth in the ‘Third Mumbai.’ With its potential to bring financial, social, educational, and industrial progress to the Mumbai Metropolitan Region, it is set to redefine the region’s future. Employment opportunities are expected to burgeon, further contributing to the region’s transformation.

The Mumbai Trans Harbour Link, with its marriage of cutting-edge technology, ecological awareness, and economic foresight, is not just a bridge over water; it’s a bridge towards a future where urban connectivity harmonizes with sustainable progress.
