Mumbai Trans Harbour Link - Construction

The tender for the construction of the bridge was awarded to Larsen & Turbo, IHI, Tata Projects, and Daewoo. The project's 1 &3 packages were bagged by L&T and were a joint bid with IHI. Package 2 was awarded to Tata Projects which was in a joint bid with Daewoo.

The bridge will have 148 steel decks, and 4 km around the middle part will have spans at the height of 110 meters, enabling the ships to travel easily through the sea routes. MMRDA or Mumbai Metropolitan Region Development Authority manages the construction. Around 270 pillars were erected and 177 of these will be in the sea. This is also the first project in India to use the Automatic Grider Launcher system.

There were multiple complications during the construction, the major one being the COVID-19 pandemic, which extended the timeline of completion. The second was the objection from the local fishing communities, who would loose their livelihood due to the construction. The MMRDA has solved the same by providing them with adequate measures to safegaurd their lives till the construction is over. The third complication was due to the pollution of the environment, as the debris and sound can cause to the ecological system. The authorities had to cut down 455 trees for the construction of the same but promised to plant another 500 to make for these, and an additional 2000 will also be planted in the city for the same.

The temporary sea bridge of 5.6 km made along with the main one, which aided in the construction will not be demolished but rather converted into a bird watching platform for enthusiasts. The region is home to flamingoes and many migratory as well as sea birds.
