The Mumbai Trans Harbour Link (MTHL) is India’s longest sea bridge, 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.
If you are looking for information about the MTHL, you have come to the right place. Here is a brief overview of the project:
- The MTHL is India’s longest sea bridge, spanning 21.8 kilometers and costing over Rs 17,840 crore.
- The project faced several challenges during its construction, including the construction of the segments of the project that lie in the marine portion, ensuring the safety of the workers, environmental challenges, and logistical challenges.
- 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.
- 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.
- The utilisation of pre-cast concrete segments further underscored the project’s commitment to efficiency. Manufactured off-site in specialised factories, these segments are then transported to the construction site.
- The incorporation of orthotropic steel decks is another standout feature of the MTHL. These specialised steel decks facilitate spans that are up to three times longer than conventional norms.
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.
