A 1464 MT steel bridge, measuring 14.6 m in height and 14.3 m in width, has been constructed at a workshop in Trichy, Tamil Nadu, and transported to the installation site via trailers. This bridge is the fourth of 28 planned for the bullet Train corridor.
In another development for the Mumbai-Ahmedabad Bullet Train Project, a new 100 m steel bridge was inaugurated on August 25 near Silvassa, in Dadra & Nagar Haveli.
To facilitate the launching, an 84-meter-long temporary launching nose, weighing 600 MT, was attached to the main bridge to eliminate the need for any intermediate supports, and additional temporary supports were installed to enhance stability during the launch.
A total of 27,500 high-strength friction grip (HSFG) bolts were used to connect the components of the launching nose, while approximately 55,250 Tor-Shear Type High Strength (TTHS) bolts, complete with C5 system painting and elastomeric bearings, were employed for the main bridge.
At a height of 14.5 m from the ground, the steel bridge and its launching nose were assembled on temporary trestles, then moved into place using an automatic system consisting of two semi-automatic jacks, each with a capacity of 250 tons, operated with mac-alloy bars.
The Bullet Train project is being executed with meticulous attention to safety and engineering quality, drawing on Japanese expertise while increasingly utilizing Indian technical and material resources in alignment with the “Make in India” initiative.
This bridge marks the completion of the fourth of 28 planned steel bridges for the corridor, which includes 24 river bridges in total—20 in Gujarat and 4 in Maharashtra. Out of the 20 bridges in Gujarat, 10 have already been completed.
The project was officially launched by Prime Minister Narendra Modi and then-Japanese Prime Minister Shinzo Abe in Ahmedabad on September 14, 2017.
The National High-Speed Rail Corporation Limited (NHSRCL) was established on February 12, 2016, under the Companies Act of 2013, with the goal of financing, constructing, maintaining, and managing India’s High-Speed Rail Corridor.
This company operates as a ‘Special Purpose Vehicle’ in a joint venture, with equity investments from the Central Government through the Ministry of Railways and the governments of Gujarat and Maharashtra.
