The Mumbai-Ahmedabad Bullet Train project marked a significant achievement with the successful launch of a 100-meter span steel bridge over NH-48 near Nadiad, Gujarat, announced the National High Speed Rail Corporation Limited (NHSRCL) here on Friday, emphasizing the bridge’s creation under the ‘Make in India’ initiative.
NH-48, a six-lane highway, saw its first bridge span launched across three lanes with a meticulously planned slide of approximately 200 meters, ensuring minimal disruption. The 1414 metric ton structure stands 14.6 meters high and 14.3 meters wide, and is designed for a 100-year lifespan. This steel bridge has been manufactured in a workshop located in Salasar , Hapur , Uttar Pradesh.
Constructed with 57,200 Tor-Shear Type High Strength bolts and advanced painting and bearing systems, the steel bridge was assembled on temporary trestles and moved with semi-automatic jacks. NHSRCL plans 28 such bridges along the corridor, with seven already completed in Gujarat.
This ‘ Make in India ‘ steel bridge consists of two 100-metre long steel spans to cross NH-48 for the bullet train corridor, one of which was successfully launched.
28 steel bridges have been planned for this entire corridor . Out of which 11 steel bridges are in Maharashtra and 17 steel bridges are in Gujarat. 7 steel bridges have been successfully launched in Gujarat on railway/DFCC tracks, highways and Bhilosa industry.
