The National High-Speed Rail Corporation Ltd (NHSRCL), which is executing the 508-km project, said the 300 km of viaducts were completed with the launch of a 40-metre-long girder near Surat in Gujarat.

The NHSRCL said that of the 300 km of the superstructure, 257.4 km was constructed through the FSLM, including 14 river bridges, 37.8 km through Span by Span (SBS), 0.9 km of steel bridges (10 spans ranging from 60 to 130 m in 7 bridges), 1.2 km PSC bridges (20 spans ranging from 40 to 80 metres in 5 bridges) and 2.7 km in station building.

It said the FSLM has significantly accelerated construction, as full-span girder erection is up to 10 times faster than conventional segmental methods.

The agency said that the 383 km of pier work, 401 km of foundation and 326 km of girder casting has also been completed for the bullet train project.

Mumbai-Ahmedabad Bullet Train Project

The bullet train project connecting Mumbai with Ahmedabad will have 12 stations, including nine in Gujarat and three in Maharashtra.

While the one in Mumbai is underground, the ones at Thane, Virar, Boisar, Vapi, Bilimora, Surat, Bharuch, Vadodara, Anand, Ahmedabad, and Sabarmati are elevated.
