Mumbai-Ahmedabad Bullet Train: First 'Make in India' steel bridge ready for launch, know what is its specialty?
200-meter-long steel bridge to be built on National Highway-48 in Nadiad, Gujarat, expected to be completed by August 2025
The work of the Mumbai-Ahmedabad Bullet Train Project is going on at a fast pace. All preparations have been made to launch the first part of the 200-meter-long 'Make in India' steel bridge for this project. This bridge will be installed on National Highway 48 near Nadiad in Gujarat. It is being told that this pool will be ready by August 2025. Let us tell you that this bullet train project is 508 km long. Its 352 km part falls in Gujarat and 156 km in Maharashtra. This bullet train is going to run from Mumbai to Ahmedabad.
A total of 28 steel bridges have been planned in the MAHSR project. Of these, 11 steel bridges are in Maharashtra and 17 in Gujarat. Six steel bridges have been successfully constructed in Gujarat, including railway/DFCC tracks, highways and Bhilosa Industries. The first span of this steel bridge is planned to be launched in March 2025 and completed by August 2025.
What is the specialty of this bridge?
The bridge has two spans of 100 metres each and will be launched near Nadiad on National Highway-48 (connecting Delhi, Mumbai and Chennai).
14.3 metres wide and 14.6 metres high, this steel bridge weighs around 1500 metric tonnes and has been fabricated at Salasar workshop near Hapur in Uttar Pradesh.
The joining of the steel parts is done using Tor Shear Type High Strength Bolts (TTHSB), designed for a lifespan of 100 years.
The bridge parts are painted with C-5 system painting, the first of its kind in India.
Steel bridges are best suited for crossing highways, expressways and railway lines, while pre-stressed concrete bridges with spans of 40 to 45 metres are suitable for most sections including river bridges.
India has expertise in building steel bridges for heavy freight and semi-high-speed trains that run at speeds of 100 to 160 kmph. Now, the same expertise in manufacturing steel girders will be applied to the MAHSR corridor, which will have an operational speed of 320 kmph.
