70 m Steel Bridge Launched Over DFCCIL Tracks for Bullet Train Project

A 70-meter steel bridge was successfully launched over two DFCCIL tracks near Vadodara, Gujarat for the Mumbai-Ahmedabad Bullet Train project. This is the seventh steel bridge completed for the project in Gujarat, out of the planned 28 steel bridges for the entire corridor. The bridge was fabricated at a workshop in Durgapur.

Kolkata and transported on trailers to the site for installation. The bridge was launched using a 49-meter-long launching nose, weighing around 204 metric tons. The bridge fabrication utilized approximately 28800 Nos. of Tor-Shear Type High Strength (TTHS) bolts with C5 system painting and elastomeric bearings, all designed for a 100-year lifespan.

The launching was completed within 12 hours with intermittent blocks on DFCC completed in Gujarat out of the 28 planned for the entire high-speed rail corridor. tracks to ensure safety and precision. The Indian Airport Operators (ICRA) project overall airport passenger traffic to witness a healthy growth of around 7-9% YoY in FY2026.

In a significant advancement for the Mumbai-Ahmedabad bullet train project, a 70-meter-long steel bridge was successfully launched over the tracks of the Dedicated Freight Corridor Corporation of India Limited (DFCCIL) near Vadodara, Gujarat. This marks the seventh steel bridge completed in Gujarat out of the 28 planned for the entire high-speed rail corridor.

Bridge Specifications and Construction Details:

• Dimensions and Weight: The bridge measures 70 meters in length, 13 meters in height, and 14 meters in width, with a total weight of 674 metric tons (MT) Constructed at a workshop in Durgapur, Kolkata, the bridge was transported to the site using specialized trailers.
• Installation: Utilizing a 49-meter-long launching nose weighing approximately 204 MT, the bridge was installed with minimal disruption to existing rail operations.

Construction Methodology:

The assembly involved the use of around 28,800 Tor-Shear Type High Strength (TTHS) bolts, C5 system protective painting, and elastomeric bearings, all engineered for a 100-year lifespan. The bridge was assembled on-site at a height of 18 meters above ground on temporary trestles and launched using an automatic mechanism comprising two semi-automatic jacks, each with a capacity of 250 tons, and mac-alloy bars.

To secure a 100-year lifespan, the bridge has been constructed using Tor-Shear Type High Strength (TTHS) and elastomeric bearings. The assembly was carried out at a height of 18 meters above ground, supported by temporary trestles, and launched using automatic mechanisms designed for precise placement.

This launch marks another step forward for India’s ambitious bullet train project, enhancing connectivity between Mumbai and Ahmedabad while bolstering the nation’s steel industry. It also demonstrates the technical capabilities required for high-speed rail infrastructure in India.
