Bullet train project: NHSRCL completes 200-metre steel bridge over NH-48 in Gujarat

Anand: The National High-Speed Rail Corporation Limited (NHSRCL) has completed the ninth steel bridge on the Gujarat section of the Mumbai–Ahmedabad High-Speed Rail (MAHSR) bullet train corridor. The new structure, spanning 200 meters across National Highway 48 in Anand district, consists of two steel spans of 100 meters each.

In a press release, NHSRCL said: “The second 100 m span of the 2 × 100 m long steel bridge was successfully launched over NH-48 (connecting Delhi, Mumbai & Chennai) near Nadiad, Gujarat, for the Mumbai–Ahmedabad Bullet Train project. The first 100 m span of this steel bridge was completed in April 2025. This is the ninth steel bridge completed out of the planned 17 steel bridges in Gujarat.”

Comprising two spans of 100 m each, this steel bridge weighs around 2,884 metric tons, stands 14.6 meters tall, and is 14.3 meters wide. Fabricated at the workshop in Salasar, near Hapur, Uttar Pradesh, the steel bridges are designed for a 100-year lifespan.

NH-48 is one of the busiest six-lane highways (three lanes on each side). The second span of the bridge was launched across the highway by sliding it 100 m from one end. The launching was carried out on a schedule to ensure smooth traffic flow on the busy highway, minimizing disruption to road users.

This 200 m long steel bridge is constructed with approximately 1,14,172 Tor-Shear Type High Strength (TTHS) bolts, a C5 system painting, and elastomeric bearings. It was assembled on temporary trestles at a height of 14.9 meters above the ground and was moved using an automatic mechanism with two semi-automatic jacks, each capable of lifting 250 tons, with Mac-alloy bars.

There are 28 steel bridges planned for the entire corridor, of which 11 are in Maharashtra and 17 are in Gujarat. DeshGujarat
