India’s ambitious Mumbai–Ahmedabad High-Speed Rail (MAHSR) project has reached a significant construction milestone with the completion of 300 kilometers of viaducts, marking substantial progress in the country’s first bullet train corridor.
The National High-Speed Rail Corporation Limited (NHSRCL) announced that this achievement was marked by the successful launch of a 40-meter-long full-span box girder near Surat, Gujarat. Out of the 300 km of superstructure completed, 257.4 km were constructed using the Full Span Launching Method (FSLM), which includes 14 river bridges. An additional 37.8 km were built using the Span by Span (SBS) method, alongside 0.9 km of steel bridges, 1.2 km of prestressed concrete (PSC) bridges, and 2.7 km within station buildings.
The FSLM technique has significantly accelerated construction, allowing for girder installation up to ten times faster than traditional methods. Each full-span box girder weighs approximately 970 metric tonnes.
Beyond the viaducts, the project has also completed 383 km of pier work, 401 km of foundation work, and 326 km of girder casting.
The 508-km MAHSR corridor aims to connect Mumbai and Ahmedabad, significantly reducing travel time between the two cities. The project is being developed with financial and technical assistance from Japan and is expected to revolutionize India’s rail infrastructure.
With the completion of 300 km of viaducts, the MAHSR project moves closer to its goal of introducing high-speed rail travel in India, promising enhanced connectivity and economic growth along the corridor.
