The Mumbai–Ahmedabad Bullet Train project has successfully completed the launching of viaduct over the Kalupur flyover, which is a Railway Over Bridge (ROB) over the Sabarmati-Mumbai main line (Western Railways) in Amdavad district. The viaduct runs parallel to the existing railway line, and the launching over the flyover was completed on 25th May 2026.
The work involved the launching a 45-meter-long bridge using the Span-by-Span (SBS) method.
Salient Features:
- Length of span over flyover: 45 m
- Height of viaduct (ground to rail level): 19.5 m
- Number of segments launched: 19

The Kalupur flyover is one of Amdavad’s busiest two-lane flyovers, serving as an important connectivity route between Shahibaug, Asarwa, and Kalupur, and is used daily by thousands of commuters.
The span erection activities were carefully planned and executed under a controlled night block schedule. Complete closure of entry and exit points within the work zone was enforced during night hours from 00:00 hrs to 06:00 hrs, while normal traffic movement beneath the flyover was restored during daytime.
Necessary night traffic block permission was obtained from the Ahmedabad Traffic Department for the period from 22nd to 25th May 2026. Within this limited block duration, all major activities including auto-launching, segment transportation, span erection, dry matching, and gluing were completed successfully in three (03) nights.
To further reduce inconvenience to the public, necessary safety and traffic management measures were implemented including proper barricading, traffic diversion signages, advance public information regarding route diversions, deployment of adequate traffic marshals during day and night shifts, and sufficient lighting arrangements during night-time operations.
