Mumbai Trans Harbour Link (MTHL)

The Mumbai Trans Harbour Link (MTHL), a titan of infrastructure rising from the waves of the Thane Creek, is more than just a bridge. It's a 21.8 km saga of human ingenuity, a symbol of progress cutting through the bustling heart of the Mumbai Metropolitan Region. Inaugurated in January 2024, it claims the title of India's longest sea bridge, its silhouette etching a new chapter in the city's narrative.

Unveiling the Anatomy of a Colossus:

• 16.5 km of Oceanic Embrace: Gleaming steel decks unfurl over the Thane Creek, weaving a magnificent path adorned with breathtaking vistas of the Mumbai skyline. This sea link, a testament to modern engineering, is the star of the show.

• 5.5 km of Continental Connections: Seamlessly blending into the land on both ends, elevated viaducts bridge the gap between the sea link and the bustling cities. The journey doesn't end at the water's edge, it seamlessly integrates into the urban fabric.

• 180 Meters of a First: Spanning across the expanse like a metal titan, the 180-meter orthotropic steel deck sets a new precedent in Indian bridge construction. It's a feat of innovation, pushing the boundaries of engineering.

• Six Lanes of Smooth Flow: Three lanes in each direction, flanked by emergency lanes, create a highway of progress. Traffic snarls become a distant memory, replaced by the smooth hum of efficient commutes.

• Interchange Symphony: Strategic connections with the Sewri-Worli Elevated Connector and major highways weave a web of accessibility. Reaching your destination becomes a seamless dance, not a tedious crawl.

The Ripple Effect: Transforming Beyond Concrete and Steel:

• Time Warp: Shaving hours off commutes between Mumbai and Navi Mumbai, the MTHL transforms time into opportunity. Lost moments spent in traffic are reclaimed for families, businesses, and dreams.

• Decongestion Symphony: The clogged arteries of existing routes breathe a sigh of relief. The MTHL diverts traffic, restoring sanity to the urban grid and paving the way for a new era of mobility.

• Trade Winds Unleashed: With quicker, smoother movement of goods and people, the MTHL becomes a catalyst for economic growth. Trade flourishes, tourism thrives, and the pulse of the region picks up a vibrant pace.

• Seeds of Prosperity: The bridge acts as a magnet, attracting investments and development to both sides of the creek. New business hubs rise, job opportunities blossom, and the seeds of a brighter future are sown.

More Than Just a Bridge, a Beacon of Hope:

The MTHL is a testament to human ambition, a canvas painted with the strokes of innovation and perseverance. It stands not just as a physical structure, but as a symbol of Mumbai's unwavering spirit, its relentless pursuit of progress. As the city gazes at its reflection in the shimmering steel of the bridge, it sees not just a shortcut, but a stepping stone towards a brighter tomorrow.

Dive Deeper:

This glimpse is just the beginning. If you're curious about the fascinating journey of the MTHL, from its conception decades ago to its triumphant completion, or the intricate engineering marvels that brought it to life, ask away! I'm eager to share the full story, one fascinating detail at a time.

MTHL, Mumbai Transport Harbor Link, popularly known as Atal Setu, was first proposed in 1981 by a steering committee led by Shri JRD Tata. After three decades of hard efforts, MMRDA has planned this plan in EPC format. The MTHL Bridge is 21.8 km long, making it the longest sea bridge in India and the 10th longest sea bridge in the world. It is divided into three packages and includes information from leading global engineering giants Kelly Geely, South Korea's Daewoo Engineering and Bharat Construction and Tata Projects Limited. Daewoo Tata Projects Joint Venture takes pride in the Mumbai Transport Harbor Link Package 2, which has created a complete safety net at the time of construction. MTHL Package 2, which is 7.8 km long, starts from Shivaji Nagar Inul, Navi Mumbai and continues till Mid Sea, which connects to Package 1 and further connects Mumbai's SEI MTHL. Package 2 includes concrete decks and steel decks, technically called orthotropic steel decks (OSD). The OSD section is 1.8 km and has a longest span of 180 metres.

   This project will create three types of geological formations, land – tidal and marine. The marine section covers 4.4 kilometres, the intertidal section extends over 2 kilometres, and the land Shivaji Nagar interchange is 1.4 kilometres. The interchange consists of six ramps that connect Mumbai to Navi Mumbai International Airport, JNPT and Nana Region. Construction of MTHL Package 2 started in March 2018 along with establishment of Shivaji Nagar UL Navi Mumbai Casting Yard and construction of an important 2 km long access bridge
