AHMEDABAD (Metro Rail News): The Mumbai-Ahmedabad Bullet Train project has achieved another major construction milestone in Gujrat. Engineers have completed the launch of a 45 meter long viaduct span over busy Kalupur Flyover in Ahmedabad, helping the HIgh-Speed rail corridor move closer to completion. The viaduct runs parallel to the existing Mumbai-Sabarmati railway line of Western Railway. Project teams completed the bridge launch on May 25, 2026.
Bridge Installed over key Ahmedabad flyover
The new span crosses the Kalupur flyover, a railway overbridge that carries thousands of vehicles every day. The flyover connects Shahibaug, Asarwa and Kalupur and serves as an important route for daily commuters. Engineers used the Span-by-Span (SBS) construction method to place the bridge segment above the flyover.
Key details of the structure
- Length of span: 45 meters
- Height from ground level to rail level: 19.5 meters
- Number of segments used: 19
- Total weight of span: 1,200 meters tonnes
Teams finished the work in three nights
The construction team carried out the work between May 22 and May 25 after receiving permission from the Ahmedabad Traffic Department for night traffic blocks. To ensure safety, authorities closed entry and exit points within the work zone between midnight and 6 am. During this limited time, engineers completed all major activities, including,
- Transportation of segments
- Auto-launching operations
- Span erection
- Dry matching
- Gluing works
The team completed the entire operation in just three nights and reopened the area for normal traffic during the daytime.
Traffic management plan reduced disruptions
Project officials put several measures in place to reduce inconvenience to the public during construction. These included,
- Barricading around the work area
- Traffic diversion signs
- Advance public information about route changes
- Deployment of traffic marshals during day and night shifts
- Additional lighting for night-time work
These arrangements helped maintain traffic movement while construction continued above the flyover.
Progress continues across Ahmedabad section
The Ahmedabad section of the bullet train corridor includes several complex crossings over railway lines, roads, canals and bridges. The corridor passes through 31 crossings in Ahmedabad district, including:
- 8 Indian Railways crossings
- 16 canal crossings
- 1 crossing over the Sabarmati River
- Road flyovers, roads and underpasses
- 6 steel bridges
So far, project teams have completed work at 23 of these 31 crossings. The latest achievement at Kalupur Flyover adds another important link to the Mumbai-Ahmedabad Bullet Train corridor, which remains India’s first high-speed rail project.
