100 km of Viaduct completed on Mumbai-Ahmedabad high speed corridor


In a groundbreaking update, the National High-Speed Rail Corporation Limited (NHSRCL) recently announced a significant achievement in the construction of the Mumbai-Ahmedabad Bullet Train Project. As of November 21, the project has seen the completion of an impressive 103.24 km of elevated viaduct and 251.40 km of pier erection work. Let's delve into the key milestones and innovations that mark this transformative project.

Viaducts and Piers

The heart of the project lies in the meticulously constructed viaducts spanning 100 km, consisting of 40 m long full-span box and segment girders. Supported by piers ranging from 10 to 20 meters in height with a circular diameter of 4-5 meters, these engineering marvels showcase the prowess of the Mumbai-Ahmedabad High-Speed Corridor.

Bridging Rivers

The project has triumphed over geographical challenges by constructing viaducts and bridges over six rivers in Gujarat. From Par River in Valsad District to Venganiya River in Navsari District, each bridge stands as a testament to the seamless integration of technology and nature.

Piercing Noise Barriers

NHSRCL has prioritized passenger comfort by initiating the installation of noise barriers along the bullet train route. These barriers, inspired by Shinkansen Technology, are 2 meters high and 1 meter wide concrete panels strategically placed to reflect and distribute the sound generated by the high-speed train, ensuring a quieter travel experience.

Innovative Tracks

Surat witnesses a historic first with the introduction of a Reinforced Concrete (RC) track bed, utilizing the J-slab ballastless track system for the first time in India. This innovative track system promises durability and efficiency, further elevating the standards of rail infrastructure in the country.

The Magnitude of MAHSR

The Mumbai-Ahmedabad High-Speed Rail (MAHSR) project, with an estimated cost of 1.08 lakh crore, is India's maiden venture into high-speed railway corridors. As the project continues to unfold, it not only promises faster travel but also stands as a symbol of India's commitment to technological advancements in the realm of transportation.


The completion of 103.24 km of elevated viaduct and 251.40 km of pier erection work is a testament to the relentless pursuit of excellence in the Mumbai-Ahmedabad Bullet Train Project. As the nation eagerly awaits the inauguration of this high-speed corridor, it reflects a stride towards a future where connectivity, innovation, and efficiency converge on the tracks of progress.
