The Mumbai–Ahmedabad Bullet Train project has achieved another milestone with the successful launching of its 10th steel bridge in Ahmedabad, Gujarat. The 60-meter-long bridge was installed over a Western Railway facility (laundry) situated adjacent to existing railway tracks.
Following several months of detailed planning and logistical preparation, the bridge launching was executed with remarkable precision in just seven hours. This is the first steel bridge launched within the Ahmedabad district for the project.
For the transverse launching process, the bridge was pre-assembled at a height of 16.5 meters above ground level on temporary trestles. It was then side-slewed into its final position using two semi-automatic jacks, each with a 200-ton capacity, supported by locking trolleys to ensure stability and control.
The bridge weighs approximately 485 metric tons and measures 12 meters in height and 11.4 meters in width. It was fabricated at a specialized workshop in Wardha (Nagpur, Maharashtra) and transported to Ahmedabad using custom-designed trailers. The bridge construction involved the use of around 20,360 Tor-Shear Type High Strength (TTHS) bolts, complemented by a C5 protective paint coating system and elastomeric bearings to enhance durability and reduce vibration impact.
A total 28 steel bridges are planned for the entire corridor, out of which 17 are in Gujarat and 11 in Maharashtra.
