November 25, 2025: The Mumbai–Ahmedabad High-Speed Rail (MAHSR) project has achieved another major construction milestone with the successful launch of its 11th steel bridge, a 70-metre-long structure positioned over the Cadilla flyover in Ahmedabad district, Gujarat. This installation strengthens the project’s progress as work continues at pace across the high-speed rail alignment.
The bridge, weighing 670 metric tons, has been constructed parallel to the existing Ahmedabad–Mumbai railway corridor. Standing 13 metres in height and 14.1 metres in width, the massive steel structure underscores the engineering scale of India’s first bullet train project. Fabricated at a dedicated workshop in Navsari, Gujarat, the completed components were transported to the site using heavy-duty trailers designed for oversized cargo.
Erection of the bridge was carried out on specially designed steel staging elevated 16.5 metres above ground level. This staging was strategically positioned beside the Cadilla flyover and in proximity to operational railway tracks, ensuring minimal disruption to ongoing rail movement. Engineers assembled the structure using approximately 29,300 Tor-Shear Type High Strength (TTHS) bolts, known for their superior load-bearing capacity and safety performance. To enhance the bridge’s longevity, the entire steel surface has been coated with a C5-grade protective paint system, offering high resistance against corrosion and environmental wear.
The MAHSR corridor is planned to include a total of 28 steel bridges—17 in Gujarat and 11 in Maharashtra—forming key linkages across complex terrain and existing transport infrastructure. With the successful launch of this 11th bridge, the project continues to move steadily toward realising India’s most advanced high-speed rail network. Each completed segment brings the country closer to introducing world-class bullet train services between Mumbai and Ahmedabad, marking a transformative chapter in national transportation infrastructure.
