New Delhi: Union Railway Minister Ashwini Vaishaw on Tuesday announced the completion of the 300-km viaduct for the Mumbai-Ahmedabad bullet train project. Taking to his social media platform X, the Minister shared a video of the construction of the structure through the Full Span Launching Method (FSLM).
Out of the 300 km structure, 257.4 km has been constructed with FSLM, which was the major reason for the fastening of the work. According to the NHSRCL, 14 river bridges (37.8km) through Span by Span (SBS), 0.9km of steel bridges (10 spans ranging from 60 to 130 m in 7 bridges), 1.2 km PSC bridges (20 spans ranging between 40 and 80 metres in 5 bridges) and 2.7 km in station building were build through FSLM.

The agency said that the 383km of pier work, 401km of foundation and 326 km of grider casting has also been completed for the bullet project.
The materials used in this project such as launching gantries, bridge grantries, and grider transporters were all made in India itself. The completion has been achieved after successfully launching a 40 meter long box girder near Surat in Gujarat.
With the full-span technology, the construction speed has increased by 10 times. Each span girder weighs about 970 tonnes. Additionally, more than 3 lakh noise barriers have been installed on both sides of the viaduct to reduce noise.
Mumbai-Ahmedabad Bullet Train project
The Mumbai-Ahmedabad bullet train project is a faster mode of transport for passengers between the two cities. There are 12 stations planned for the project, which includes nine in Gujarat and three in Maharashtra. The Mumbai station is the only undergrounded station in this project while the rest are in elevated mode. The list includes Thane, Virar, Boisar, Vapi, Bilimora, Surat, Bharuch, Vadodara, Anand, Ahmedabad, and Sabarmati.
The journey of the train from the boarding point to the final destination is expected to be around three hours rather than the regular six to eight hours through passenger trains.
