In Indian Railways and world geography, the proposed worlds highest railway bridge in Jammu and Kashmir is planned to be constructed over which river?

Introduction / Context:
The question relates to an important geography and infrastructure fact about India. India is constructing one of the highest railway bridges in the world as part of the Udhampur–Srinagar–Baramulla rail link in the Jammu and Kashmir region. This project is very important for connectivity, national integration and strategic movement in a mountainous area. Knowing the name of the river over which this bridge is being built helps aspirants connect current affairs, geography and basic railway knowledge, which are frequent themes in competitive examinations.

Given Data / Assumptions:

• A very high railway bridge is planned in Jammu and Kashmir.
• The bridge is considered among the highest railway bridges in the world.
• The project is part of an important railway link in a Himalayan region.
• The options list four major rivers of India: Ganga, Chenab, Yamuna and Kaveri.

Concept / Approach:
The key to this question is recognition of a famous infrastructure project often called the Chenab Bridge. It is a steel and concrete arch bridge being built across the Chenab River. It is designed to have a very high deck above the river bed, making it one of the highest railway bridges globally. By connecting the clue words highest railway bridge, Jammu and Kashmir and Indian Railways with current affairs reading, we can recall that the relevant river is the Chenab, not the Ganga, Yamuna or Kaveri, which are important but unrelated to this specific project.

Step-by-Step Solution:
Step 1: Note that the project is in Jammu and Kashmir, a northern Himalayan region. Step 2: Recall the major rivers flowing through this region, such as Jhelum, Chenab, Indus and their tributaries. Step 3: Remember that the famous high arch railway bridge under construction is widely known as the Chenab Bridge. Step 4: Observe that among the options only Chenab River matches this name and location. Step 5: Conclude that the correct answer must be Chenab River, because the bridge is named after and constructed across this river.

Verification / Alternative check:
A quick mental check is to ask whether any high profile railway project across the Ganga, Yamuna or Kaveri has been advertised as the highest bridge in the world. In most exam oriented newspapers and yearbooks the title is always linked to the Chenab Bridge in Jammu and Kashmir. This independent recall confirms that Chenab River is correct. The other rivers are important in other regions but have not been associated with such a record breaking railway bridge project.

Why Other Options Are Wrong:
Ganga River is a major river of northern India but no globally record breaking railway bridge of this type is being constructed across it in Jammu and Kashmir. Yamuna River flows mainly through northern and central India near cities like Delhi and Agra, not in the mountainous stretch where this high arch bridge is planned. Kaveri River flows in southern India through Karnataka and Tamil Nadu, far from Jammu and Kashmir, so it cannot be the correct river for this project.

Common Pitfalls:
Candidates sometimes choose Ganga or Yamuna simply because these rivers are very famous and appear frequently in exams. Another mistake is to answer based only on river size or religious importance rather than the specific location of the railway project. Some learners also confuse the Chenab Bridge with road bridges in other Himalayan regions. To avoid such errors, always link the project name, region and river together in memory, and revise a list of major Indian infrastructure projects before the exam.

Final Answer:
The planned worlds highest railway bridge in Jammu and Kashmir is being constructed across the Chenab River.
