This is the ninth steel bridge completed for the project

The second 100 m span of a 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 span of 100 m for 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 2884 metric tons, stands 14.6 meters tall, and is 14.3 meters wide. Fabricated at a workshop in Salasar near Hapur, Uttar Pradesh, the steel bridge is 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 the span for 100 m from one end. The launching was carried out in a planned schedule to ensure smooth traffic flow and minimize disruption to road users.

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

A total of 28 steel bridges are planned for the entire corridor, out of which 11 are in Maharashtra and 17 are in Gujarat.
