Sabarmati Bullet Train Bridge: 12-Story High Structure Progresses

The 36-meter-tall Sabarmati bridge for the Mumbai-Ahmedabad bullet train project is progressing steadily in Ahmedabad. The 480-meter-long bridge has all eight circular piers completed, with three of five 76-meter spans finished. Constructed using the Balanced Cantilever Method, the bridge is built without scaffolding to minimize obstruction. Special measures ensure uninterrupted river water flow during construction, with all foundation and substructure works now complete.

Sabarmati bridge for bullet train project progresses steadily in Ahmedabad

The 36-meter-tall Sabarmati bridge for the Mumbai-Ahmedabad bullet train project progresses steadily, with all piers completed and three spans finished.

"The bridge construction work has achieved remarkable progress, with all foundation and substructure works now complete. - NHSRCL official statement"

Ahmedabad, April 27

The construction of a 36-meter-tall bridge equivalent to a 12-storey building over the Sabarmati River in Amdavad is advancing steadily as part of the Mumbai-Ahmedabad Bullet Train Project, according to an official statement by the National High Speed Rail Corporation Limited.

The 480-metre-long bridge is being built alongside the Western Railway's Ahmedabad-Delhi main line.

Strategically located between the Sabarmati and Ahmedabad Bullet Train stations, it lies approximately 1 km from the Sabarmati Bullet Train station and about 4 km from the Ahmedabad Bullet Train station.

All eight (08) circular piers with diameters of 6 to 6.5 meters are completed, four (04) are located within the river bed, two (02) are placed on the river banks (one on each side), and two (02) are outside the river bank. The pier heights vary from 31 to 34 meters. It has been designed with strategic placement of piers to minimise obstruction in the river waterway.

The bridge comprises 5 spans of 76 meters and 2 spans of 50 meters, with each span being constructed using 23 segments being cast in situ (construction at the site). It is being constructed by using the Balanced Cantilever Method, a specialised construction technique ideal for long-span bridges over deep waters and rivers.

The release stated that the concept of this construction method is to construct a bridge without installing scaffolding systems under the bridge and complete the superstructure of the bridge by sequentially joining the segments to form a span by post-tensioning and balancing the left and right from each pier using special erection equipment. This creates a continuous and stable bridge deck.

The bridge construction work has achieved remarkable progress, with all foundation and substructure works now complete. Three spans of 76 meters are completed, while the superstructure activities, including pier head construction and segment casting, are currently underway.

Special emphasis has been given to maintaining uninterrupted water flow in the river during the entire construction process. Hume pipe culverts have been installed within the temporary embankment along with a maintained natural discharge channel, allowing continuous and free movement of water.

These measures ensure that the river's flow remains continuous and unaffected by construction activities.

Impressive engineering update! The 36-meter height and strategic pier placement to maintain water flow show careful planning. Looking forward to seeing the bridge and the train operational. 👍

This is going to be a game-changer for travel between Mumbai and Ahmedabad. But I do hope the project doesn't get delayed further - we've been hearing about this for years! The engineering sounds solid though, especially with the pier design to avoid obstructing the river. Let's see if they finish on time this time. 🤞

Great to see such complex construction happening in Gujarat! The Balanced Cantilever Method is no joke - very advanced stuff. Special attention to river flow continuity is commendable. Hope all the contractors maintain safety standards as well. 💪

I'm happy about the progress, but let's not forget the land acquisition issues and delays that have plagued this project. Also, the cost has ballooned significantly. While the bridge work is impressive, I wish there was more transparency on the overall budget and timeline. Let's hope this isn't another vanity project that benefits only a few. 😕

The engineering details are fascinating! Eight circular piers, 6 to 6.5 meters in diameter, and the segments being cast in situ - truly modern infrastructure. I just hope the local residents near Sabarmati aren't facing too much disruption from the construction. Progress is important, but so is community consideration. 🤔
