Mumbai-Ahmedabad bullet train project latest update: The work is progressing rapidly on the Mumbai-Ahmedabad bullet train corridor. The 508-km long Mumbai-Ahmedabad High Speed Rail (MAHSR) project is under execution with technical and financial assistance from Government of Japan.
On Saturday, the National High-Speed Rail Corporation Ltd (NHSRCL) successfully launched the 10th steel bridge for the Mumbai–Ahmedabad High-Speed Rail (MAHSR) project. Measuring 60 meters in length, the bridge is situated in Ahmedabad.
The Mumbai-Ahmedabad bullet train viaduct in Ahmedabad will pass through 31 crossings including railway tracks, flyovers, canal, one river bridge crossing at Sabarmati River and six steel bridges. The NHSRCL has planned to built 28 steel bridges for the entire corridor, out of which 17 are in Gujarat and 11 in Maharashtra.
The 10th steel bridge for Mumbai-Ahmedabad bullet train project was launched over a western railway facility (laundry) located adjacent to the railway tracks. This is also the first steel bridge launched in Ahmedabad district for the project.
“With months of meticulous planning and preparation, the bridge launching was completed with precision in just 7 hours. For transverse launching of this bridge, it was assembled at a height of 16.5 metres from the ground on temporary trestles and was then side-slewed using two semi-automatic jacks of 200-ton capacity each, supported by locking trolleys for stability,” the NHRSCL said in a statement.
This 485 metric ton bridge, measuring 12 metres in height and 11.4 metres in width, was fabricated at a dedicated workshop in Wardha (Nagpur, Maharashtra) and was transported to Ahmedabad using specially designed trailers. The bridge construction utilized approximately 20360 Tor-Shear Type High Strength (TTHS) bolts, coated with C5 system protective painting and elastomeric bearings for enhanced durability and vibration control.
In a statement, the NHSRCL said: “A temporary platform measuring 35×60 metres was constructed for assembly of the main structure. To strengthen the track beam during transverse movement, additional temporary brackets were installed. In total, 14 skid arrangements were utilised out of which four were specifically for the transverse launching.”
