A high-speed rail corridor has hit the memorable milestone of its 100th kilometre of viaduct, built using an innovative launching technique.

The Indian Mumbai-Ahmedabad High Speed Rail Corridor project has been using the full span launching method (FSLM), which sees 40m box girders launched using state-of-the-art equipment. According to the National High Speed Rail Corporation, this method is ten times faster than launching span by span.

The first girder on the project was launched in November 2021. In October the railway saw its first steel prefab bridge put into place (link opens in new tab).
