Ahmedabad, Nov 24 (NationPress) The Mumbai-Ahmedabad High-Speed Rail (MAHSR) initiative achieved a significant milestone with the successful establishment of its 11th steel bridge in Ahmedabad district, Gujarat.

This 70-metre-long structure has been strategically placed over the Cadilla flyover, progressing the nation's first bullet train corridor.

Weighing 670 metric tons, this steel bridge runs parallel to the current Ahmedabad–Mumbai railway tracks, standing at a height of 13 metres and a width of 14.1 metres.

Manufactured at a specialized workshop in Navsari, Gujarat, the structure was transported to the site utilizing heavy-duty trailers before being assembled adjacent to the Cadilla flyover.

The assembly was performed on custom-designed steel staging erected 16.5 metres above ground level, ensuring minimal disruption to ongoing railway activities. Constructed using approximately 29,300 Tor-Shear Type High Strength (TTHS) bolts, the bridge also features a C5-grade protective coating to improve durability against corrosion.

The MAHSR corridor will ultimately include 28 steel bridges, with 17 in Gujarat and 11 in Maharashtra. The installation of this 11th bridge signifies steady advancement on one of India’s most ambitious infrastructure projects, aimed at significantly shortening travel time between these two major cities.

The Mumbai-Ahmedabad bullet train, officially known as the Mumbai-Ahmedabad High-Speed Rail (MAHSR) corridor, is transforming from a mere concept into a tangible reality.

Stretching approximately 508 km, this corridor will link India’s financial capital with the economic center of Gujarat, reducing travel time to about 2 hours and 7 minutes, as per recent updates.

The project is being developed by the National High-Speed Rail Corporation Limited (NHSRCL), with substantial financial and technical support from Japan, including a significant loan from the Japan International Cooperation Agency (JICA).

The total estimated cost now stands at Rs 1.08 lakh crore, with around Rs 78,839 crore already spent as of mid-2025. Construction is advancing rapidly. As of September 2025, NHSRCL reported that over 320 km of the viaduct is completed, along with 397 km of pier works and 408 km of foundation.

Additionally, more than 1,000 overhead electrification masts have been installed, and significant tunneling operations are underway, including a 7-km undersea tunnel near Mumbai and several mountain tunnels in Maharashtra.
