The shooting corridor between Mumbai and Ahmedabad achieved a significant building milestone with the completion of 300 km of viaducts, announced on Tuesday (May 20, 2025) National High Speed Rail Corporation Limited (NHSRCL).
“This success was marked by the start of 40 meters long full -fledged box near Surrat, Gujarat,” NHSRCL said in a statement.
The 300 km of the viaduct superstructure was built 257.4 km using the full span method (FSLM), including 14 river bridges. Another 37.8 km was built using the SPAP by SPAN (SBS) method, while 0.9 km includes steel bridges in 10 span ranges ranging from 60 to 130 meters on seven bridges. Another 1.2 km is built using preliminary concrete bridges (PSC) with 20 span between 40 and 80 meters and built 2.7 km in the buildings of the station.
For 257.4 km of viaduct created by FSLM and 37.8 km using SBS, 6,455 and 925 span of 40 meters were deployed.
In particular, the project promoted the use of indigenous and manufactured devices such as Straddle carriers, Gantries, Bridges and Beam Transporters. “This means the first for Indian infrastructure and represents the growing abilities of India in high -speed rail technology with the support of the Japanese government,” NHSRCL said.
The spokesman said that the adoption of the launch method of the full range “has accelerated the design significantly, because the erection of the full span beams is up to ten times faster than the conventional segment method”. Each full span beam weighs approximately 970 metric tons, while segmented beams are used selectively in places where the installation is not full of span feasible.
To support the scope of the construction, 27 reserved yards were set up along the corridor. Steel bridges are produced in seven workshops across the country – three in Gujarat and one in Uttar Pradesh, Tamil Nadu, Maharashtra and West Bengal.
More than 3 lakh barriers were installed along the viaducts in an effort to reduce noise pollution.
In addition to the design of the viaduct, NHSRCL completed 383 km of work on the pier, 401 km of endowment and 326 km of casting beams. Tracking work through viaducts also began, with approximately 157 kilometers with reinforced concrete tracks construction so far in Gujarat.
“In Maharashtra and Gujarat, compositions from modern infrastructure are also formed,” the spokesman added. “Stations that will be integrated into railway and road -based transport systems to provide trouble -free travel to passengers are constantly progressing.”
