The Chenab Rail Bridge built on the Chenab River in Jammu and Kashmir is the highest railway bridge in the world. This bridge 1315 meters long stands on the difficult land of the Himalayas. Satellite photos and 3D technology made its construction more exciting. Let’s learn about this engineering miracle …

2017: Construction started at Dharot on both sides of the Chenab river. The photographs were seen in the photographs.
2022: The 1,315 meter long steel arch is almost complete, just a small portion remains to be added
February 2025: The bridge was fully prepared in satellite photos, which is made of 25,000 tons of metal – three times more than the Fil Tower!
What is Chenab Rail Bridge?
Chenab Rail Bridge is part of Udhampur-Srinagar-Baramulla rail link. It is the highest railway bridge in the world, which is 359 meters above the Chenab River.

- Length: 1,315 m.
- Height: 359 meters (from river).
- Metal: 25,000 tonnes of steel, including 14 pillars.
- place: Dharot of Jammu and Kashmir, in the lap of the Himalayas.
- Objective: Connecting Kashmir to the rest of the country by rail. The challenges of the Himalaya
The Himalayas are a young mountain range, whose land was not fully understood. This area is in earthquake Zone-5, where there is a risk of large earthquakes. Indian Railways made special preparations for this …

- Earthquake protection: IIT Roorkee modeling earthquakes, so that the bridge could bear earthquake (2001 Gujarat earthquake) like 7.7 Richter.
- Strong winds: The bridge was designed to bear 266 km/h.
- Strong: Even if a pillar is broken, the bridge will remain standing.
- Explosion protection: According to Facons (Shapoorji Palonji Group), the bridge can bear 40 kg TNT explosion. Even if the pillar is damaged, trains will run at a slow pace.
Difficulties for construction
It was not easy to build Chenab Bridge. Working in the inaccessible valleys of the Himalayas was challenging. It was difficult to bring heavy machines and goods. Roads were narrow and the weather was bad. Unstable soil and rocks of the Himalayas complicated the design. It was made anti-blast amid the danger of terrorist attacks. 3D modeling and satellite photographs helped design and manufacture. Facons crossed these challenges and built this bridge in 10 years.
Amazing of satellite and 3D technology
Satellite photographs captured every stage of construction. Pictures from 2017 to 2025 show how this huge structure was prepared. The engineers tested every small details of the bridge with 3D modeling, such as the size of the arch and the strength of the pillars. These pictures from the satellite helped track the progress of construction and understand the land of the Himalayas.
