Mumbai-Ahmedabad Bullet Train Big Update: 17 Steel bridges now complete in Gujarat, new bridge weighs around…, top speed to be…
New Delhi: In a major development that promises to make the traveling experience of passengers comfortable and convenient, the Indian Railways has completed the eighth steel bridge of the Mumbai-Ahmedabad Bullet Train project. This has marked nearly 50 percent progress on the 17 planned steel structures in the state.
It is important to note that the latest bridge, a 100-metre-long span, was successfully launched over Dedicated Freight Corridor (DFC) tracks near Bharuch. A total of 28 such bridges have been planned on the entire Mumbai-Ahmedabad high-speed rail corridor, with 17 in Gujarat.
Here are some of the key details:
- The newly launched bridge weighs around 1,400 metric tons, stands 14.6 metres tall, and spans 14.3 metres wide.
- A total of 28 such bridges have been planned on the entire Mumbai-Ahmedabad high-speed rail corridor, with 17 in Gujarat.
- It was fabricated at a workshop in Trichy and transported to the site using specially designed trailers.
- An 84-metre-long launching nose weighing about 600 metric tons was used to push the bridge into place.
- The structure was built using 55,300 high-strength Tor-Shear bolts, featuring elastomeric bearings and C5-grade protective coating, all engineered to ensure a lifespan of 100 years.
To recall, the National High Speed Rail Corporation Limited (NHSRCL) had released a statement and informed that the bridge was assembled at the site at a height of 18 m from the ground on temporary trestles and was pulled with automatic mechanism of two semi-automatic jacks, each of capacity of 250 ton using mac-alloy bars.
To minimise disruption to freight movement, the launch was executed through carefully phased traffic blocks on the DFC tracks. With this, the high-speed corridor in Gujarat section now has eight completed steel bridges at key locations including Surat, Vadodara, Nadiad, Silvassa and Bharuch.
