The Mumbai Trans Harbour Link (MTHL) is India’s longest sea bridge, The Construction of MTHL which is spanning 21.8 kilometers and costing over Rs 17,840 crore. The construction of the MTHL was a massive undertaking, requiring the use of cutting-edge technology and innovative techniques.
Used Innovative Technologies
The MTHL incorporates various innovative technologies, such as Reverse Circulation Drilling (RCD) piling, Orthotropic Steel Deck (OSD) bridge girders, Stone Matrix Asphalt (SMA), wind tunnel testing for OSD bridge design, Tuned Mass Dampers (TMDs) for OSD bridges, an Open Road Tolling (ORT) system set to facilitate toll collection, full-scale vehicle impact testing for new crash barrier design, and seismic hazard analysis for design. Many of these technologies were being employed in India for the first time.
Balanced Cantilever
One of the engineering marvels employed in the construction of the MTHL is the “Balanced Cantilever” method. This strategic approach involves simultaneous construction from both ends, culminating in a meeting at the midpoint. This has not only enhanced the efficiency but also allowed the creation of longer and more intricate bridges, showcasing a paradigm shift in traditional bridge-building techniques.
Pre-cast concrete segments
The utilization of pre-cast concrete segments further underscored the project’s commitment to efficiency. Manufactured off-site in specialized factories, these segments are then transported to the construction site. This approach not only accelerated the construction process but also ensured the durability of the bridge, a crucial factor for its long-term structural integrity.
Incorporation of orthotropic steel decks
The incorporation of orthotropic steel decks is another standout feature of the MTHL. These specialized steel decks facilitate spans that are up to three times longer than conventional norms. This technological innovation not only enhanced the bridge’s overall efficiency but also created room for a more streamlined and resilient structure, capable of withstanding the test of time.
Power of technology and innovation in construction
The MTHL is a testament to the power of technology and innovation in construction. It is a shining example of how cutting-edge technology can be used to create structures that are not only efficient but also durable and resilient. The use of innovative techniques and materials has allowed the MTHL to stand as a symbol of India’s engineering prowess and technological advancement.
