Mumbai-Ahmedabad Bullet Train: First 100 Metre Span Of 'Make In India' Steel Bridge Launched Over NH-48 Near Nadiad In Gujarat

In a significant development for Mumbai-Ahmedbad bullet train project, the National High-Speed Rail Corporation Limited (NHSRCL) on Saturday (26 April) announced the successful launch of the first 100-metre span of a steel bridge over National Highway 48 near Nadiad, Gujarat.

The bridge, part of a 200 metre two-span steel structure each measuring 100 metres, crosses one of India's busiest six-lane highways that connects Delhi, Mumbai, and Chennai.

The operation involved sliding the massive steel span — weighing approximately 1,414 metric tons — over three lanes of live traffic, ensuring minimal disruption through precision scheduling.

"The first span of the bridge was launched on the highway across the three lanes by sliding the span for about 200 m from one end. The launching was carried out with a schedule to ensure smooth traffic flow on the busy highway, minimizing disruption to road users," the NHSRCL said in a statement.

Fabricated under the 'Make in India' initiative at Salasar near Hapur, Uttar Pradesh, the structure is designed for a 100-year lifespan.

The bridge was moved using an automatic mechanism with two semi-automatic jacks, each capable of lifting 250 tons, with mac-alloy bars.

The bridge is constructed with approximately 57,200 Tor-Shear Type High Strength (TTHS) bolts, C5 system painting, and elastomeric bearings.

Across the Mumbai-Ahmedabad Bullet Train corridor, 28 such steel bridges are planned, with 17 in Gujarat and 11 in Maharashtra.

So far, seven steel bridges have already been successfully launched in Gujarat over key infrastructure points like railway lines, freight corridors, highways, and industrial zones.
