The National High-Speed Rail Corporation Limited (NHSRCL) achieved a big milestone by efficiently erecting the primary metal bridge, spanning a formidable 70 metres in size, throughout National Highway 53 in Surat. This marks the preliminary step within the development of the Mumbai-Ahmedabad High-Speed Rail Corridor (MAHSRC).
The venture envisions a complete of 28 metal bridges, utilizing an estimated 70,000 metric tons of specified metal. These metal bridges will fluctuate in span size, starting from 60 meters ‘merely supported’ to a formidable 230 (130 + 100) meters of ‘steady span.’

Talking to ANI about this bridge development, Satyaprakash Mittal, Chief Project Manager of MAHSRC mentioned that in a testomony to India’s rising technical and materials capabilities, the fabrication of those metal bridges aligns with the ‘Make-in-India’ imaginative and prescient, combining Japanese experience with native assets. This enterprise highlights India’s prowess in developing metal bridges able to supporting Shinkansen Bullet trains, attaining speeds of as much as 320 kilometres per hour.
He additional mentioned that the meeting course of concerned cautious planning and precision, with the metal construction being transported over 1200 kilometres from the Hapur district close to Delhi to the set up web site. Once prepared on the workshop, the metal construction, which consists of almost 700 items and 673 Metric tonnes, was transported on trailers to the positioning of set up.
“At the site, the Steel Bridge of 12 to 14 meters in height was assembled on the staging above 10- to 12-meter-high piers. Thereafter the launching nose of approx. 200 metric tons weight was assembled with the mainbridge assembly. With massive care and expertise, the Bridge Assembly was pulled to its intended span through a specially designed pulling arrangement under the complete traffic block on National Highway,” Mittal mentioned.
It is notable that every manufacturing batch of metal was examined by Ultrasonic Testing (UT) on the producer’s premises.
The fabrication course of concerned slicing, drilling, welding, and a five-layered portray approach conforming to Japan Road Association’s “Handbook for Corrosion Protection of Steel Road Bridges”.
This accomplishment units a exceptional precedent within the development of high-speed rail corridors in India, propelling the nation into a brand new period of cutting-edge infrastructure growth.
National High-Speed Rail Corporation Limited (NHSRCL) was integrated on twelfth February 2016 beneath the Companies Act, 2013 with the thing of financing, developing, sustaining and managing the High-Speed Rail Corridor in India.
The Company has been modelled as a ‘Special Purpose Vehicle’ within the joint sector with fairness participation by the Central Government by means of the Ministry of Railways and two State Governments viz. Government of Gujarat and Government of Maharashtra.
