130 m span of a 230 m long steel bridge launched over NH-64 & Indian Railway tracks for Bullet Train Project

Mumbai Ahmedabad Bullet Train project has successfully completed the launching of 130 m span of a 230 m (130 +100) long steel bridge over National Highway-64 and Bharuch Dahej freight line of Indian Railway tracks near Kanthariya village, Bharuch district, Gujarat.

This continuous steel bridge features two spans of 130 m and 100 m. The 130 m span of this steel bridge was launched on 9th December 2025. Measuring approximately 18 m in height and 14.9 m in width, it weighs around 2780 metric tons. Fabricated at the workshop in Bhuj, Gujarat, the steel bridges are designed for a 100-year lifespan.

Constructed with approximately 1,22,146 Tor-Shear Type High Strength (TTHS) bolts, C5 system painting and metallic bearings, the bridge was assembled on temporary trestles at a height of 14 m above the ground and was pushed using two semi-automatic jacks, each capable of lifting 250 tons with mac-alloy bars.

The bridge launching was completed within 12 hours with intermittent blocks on freight tracks and road diversion on NH-64. These blocks were crucial to maintain safety and ensure precise execution during the phased launching process. All activities were carefully planned to minimize disruption to road users as well as ongoing freight operations.
