The Chenab Railway Bridge is a steel and concrete arch bridge that is under construction in Jammu and Kashmir, India. It will be part of a new railway line connecting Jammu to Kashmir. At 359 meters in height above the Chenab River, it will be the highest railway bridge in the world once completed. The bridge is 1,315 meters long with a main arch span of 485 meters and 17 total spans. It is being built to improve connectivity in the difficult terrain and provide safer travel between Jammu and Kashmir. Construction has faced challenges due to the region's harsh weather and poor geology but is expected to be finished by 2022.

2. Introduction
• Project(Indian railways)
• Located in Jammu and Kashmir
• Part of new railway line
• Material : Steel and Concrete
• Under Construction
• Joins Jammu with Kashmir

3. Chenab Railway Bridge

4. Description
Deck height (height above river) - 359m (1178
ft).
Bridge length – 1315m (4314ft).
Arch span – 485m (1532ft)
Total number of spans – 17
Max height of pier – 133.7m

6. Need
• Difficulty in travelling.
• Dangerous travelling.
• Better connectivity of J&K with ROI.

7. Site of Bridge
Located in Reasi district of Jammu and Kashmir

8. Geology
• Located in tricky section of Jammu-Baramulla
rail section (geology consists of Young
Himalayan rock)
• Poor Quality and Broken rocks
• Rock class 3 to 5 with a strength of 60-
100Mpa.

9. Design
• Planning by WSP group (Finland) , design of
arch by sub consultant leonhardt.
• Indian Railways Standards ,IS used while
designing.
• Wind speed(permissible) 100km/hr and
design life 120 years.
• Designed to resist wind speeds up to
260km/hr.
• Made of Blast proof Steel.

10. Construction
• Originally Intended to be completed by 2009.
• Halted over fear of stability and safety in 2008.
• Work restarted in 2010,with completion plan by 2015.
• Constructed by Afcons (Third largest construction
group in India).
• Two pylons erected on both sides of river.
• Two auxiliary self-propelled cable cranes were used to
tow temp. auxiliary ropes across these pylons.
• Ropes were used to support partly finished arch parts.

11. • About 25000 tonnes of steel structures,mainly
for arch bridge section.
• A cable crane built over the valley for
constructing steel structures.
• Crane can deliver Max 40 tonnes of steel.

12. Foundation
• Excavation and drilling done on both sides for
foundation
• Tallest pier is 137.7m tall , such tall structure
requires massive and strong foundation.
• Slope is also stablized by installing bolts of
length 4m , 8.5m , 11.5m.

13. Challenges
• No proper road network in challenging terrain.
• Transportation of construction equipment.
• Harsh weather conditions.

14. • Chenab railway bridge will be the biggest/longest
span/ the highest railway arch bridge in the world
• Deck height(359m)>Height of eiffel tower(324m)
• Cost=1100 crores
• Maintenance : Regular painting to avoid rust.
• Able to withstand an earthquake of magnitude 8
on richter scale
• Sensors will be installed across the bridge to keep
a check of wind velocity.
