Major Milestone for Ahmedabad-Mumbai Bullet Train Project
The construction of a 260-metre prestressed concrete (PSC) bridge over the National Expressway-4 near Kosamba, Surat, marks a significant milestone in the development of the ambitious Mumbai-Ahmedabad Bullet Train project. Completed on 22nd February 2025, the bridge is set to play a pivotal role in the connectivity between Surat and Bharuch for the high-speed rail corridor.
The bridge, which features 104 precast segments, is a prime example of advanced engineering techniques. Its unique design comprises four spans, with a configuration of 50m + 80m + 80m + 50m, and was constructed using the Balanced Cantilever Method. This method, which is particularly suited for large spans, ensures both structural stability and minimal disruption to the existing infrastructure. The successful completion of this bridge is a testament to the progress being made on the bullet train corridor, which promises to revolutionise the way people travel between these two key cities.
Situated over the National Expressway-4, which is a major artery connecting Delhi to Mumbai, the bridge was constructed with careful consideration to the ongoing construction of the expressway itself. Efforts were made to ensure that traffic on the expressway continued to flow uninterrupted throughout the bridge’s construction. This was achieved while prioritising the safety of workers and vehicles, which is a major challenge in large-scale infrastructure projects of this nature. The elevated viaduct of the bridge integrates seamlessly into the larger design of the bullet train corridor, facilitating efficient travel along the route and ensuring the project’s timely completion.
This newly completed bridge connects two important Bullet Train stations, Surat and Bharuch, reinforcing the government’s commitment to delivering a high-speed rail network. The impact of this development is far-reaching, not only enhancing transportation efficiency but also improving the overall economic landscape of Gujarat and Maharashtra by significantly reducing travel time.
As the project progresses, the Ahmedabad-Mumbai Bullet Train is expected to be a game-changer for the Indian rail network, positioning India among the leading nations with world-class high-speed rail infrastructure. However, like any major infrastructure project, it continues to face challenges relating to land acquisition, logistics, and coordination across multiple stakeholders. While the bridge is a clear success, stakeholders will need to remain focused on overcoming these hurdles to ensure the full realisation of the Bullet Train’s potential.
