Massive Infrastructure: Mumbai’s Coastal Road Is Designed To Look Like The “Sydney Harbour Bridge”

The enormous coastal road project in Mumbai has advanced significantly thanks to the loading of a 2000 metric-ton, 136-meter span bowstring bridge onto a barge at Mazgaon Dock Jetty by the Brihanmumbai Municipal Corporation (BMC), the city’s municipal authority. The massive girder, which will connect the last section of the Coastal Road to the Worli Bandra Sea connection, weighs more than thirty Boeing planes. The BMC is prepared to launch it.

Bow String Arch’s design, which pays homage to the famous Sydney Harbour bridge, has made the building go more quickly. Furthermore, the use of specialized building methods prevented obstructions to passage and preserved the livelihood of Worli fishermen. The fishermen’s community in Worli had an impact on the major Coastal Road bridge, resulting in a modification in the span from 60 meters to 120 meters.

According to Pawan Padiyar of Hindustan Construction Co. Ltd., “the final launching of the girder will take approximately two days, subject to weather and tidal conditions.”
The connecting span had very tight deadlines since a bridge structure weighing over 7000 MT needed to be designed, fabricated, assembled, and erected in about 12 months. Additionally, the construction plan had to be designed with the least possible interference with Worli fishermen’s navigation.

The approximately 5000 MT of fabrication were completed at the HMM Infra facility in Ambala, which is equipped with the latest machinery to ensure high-quality fabrication.This unusual bridge, which is 130 meters long, 27 meters wide, and 30 meters tall, and has a maximum individual member weight of 35 tons, is a monument to the creativity and inventiveness that propel infrastructure projects in India. A 2700 MT largest span is used. The greatest level of accuracy and experience are required for such thorough engineering. The Mumbai Coastal Road project was certainly not without its obstacles, given the tight schedule that called for completion in only ten months. However, with constant commitment and unmatched expertise, according to Gaurav Sood, HMM infrastructure oversees assembly and fabrication activities.

The arch was erected at the Mazgaon pier in Nhava village in order to put the prefabricated, preassembled bridge onto a barge and ship it by sea. The enormous barge of a football field is being utilized to move the arch. Marine boats are put in risk when such a large building is built in an open sea environment with minimal draft and a stony substrate. To finish the structure with the highest level of safety, the weather conditions—namely, the wind, well, and tide—must be carefully observed, according to Shailesh Thatte of Hindustan Construction Co. Ltd.
