Nw Desk The 130-meter-long steel bridge is critical to the Mumbai-Ahmedabad Bullet Train project.
New developments across sectors in India, especially in infrastructure, have garnered not just national but also worldwide attention for all the right reasons. One such development is the 130-meter-long steel bridge that was recently launched under the “Make in India” initiative over the Delhi-Mumbai National Expressway for the Bullet Train project.
The Steel Bridge reflects the country’s progress in high-speed rail infrastructure.
The Steel Bridge, a colossal structure weighing 3000 metric tons and measuring 18 meters high, 14.9 meters wide, and 130 meters long, is a testament to India’s progress in high-speed rail infrastructure under the Make in India initiative. The National High-Speed Rail Corporation Limited (NHSRCL) realized this remarkable achievement by launching the bridge over the Delhi-Mumbai National Expressway near Vadodara, Gujarat, on Sunday, June 23.
A critical component of the Mumbai-Ahmedabad Bullet Train project.
The steel bridge is also critical to the Mumbai-Ahmedabad Bullet Train project. The entire launching process of the bridge was completed within 24 hours, despite intermittent breaks to allow road traffic to pass. The structure’s fabrication required approximately 124,246 Tor-Shear Type High Strength (TTHS) bolts. It features a C5 system painting and metallic spherical bearings, ensuring a 100-year lifespan. Assembling the bridge required elevating it 15 meters from the ground using temporary trestles. An autonomic mechanism consisting of two semi-automatic jacks with a capacity of 250 tons each was also used, utilizing Mac-alloy bars to pull the bridge into place.
Highest standards of safety and engineering.
The project is a testament to visionary ideas in infrastructure and meticulous execution. This has helped maintain the highest standards of safety and engineering excellence. It optimizes Japanese expertise while utilizing India’s technical and material resources.
