Introduction to National Highways for RRB Exams
General Awareness is a scoring section in RRB NTPC, Group D, and Technician examinations. Geography forms a crucial part of this section, and questions related to transport systems, specifically the National Highways of India, are frequently asked. Understanding the classification, major corridors, and recent developments in India's highway network will help you secure essential marks.
Topic Weightage and Importance
In RRB examinations, candidates can expect 1 to 2 questions directly or indirectly from transportation and roadways. These questions typically test factual knowledge such as the longest highway, terminal points of major corridors, and executing bodies like NHAI. A clear understanding of these concepts is indispensable for clearing the cutoff.
Key Concepts and Formulas
India boasts the second-largest road network in the world. The maintenance, development, and management of National Highways are overseen by the National Highways Authority of India (NHAI), which operates under the Ministry of Road Transport and Highways.
- Longest National Highway: NH 44 (runs from Srinagar in the north to Kanyakumari in the south, covering approximately 3,745 km).
- Shortest National Highway: NH 766EE (or other designated short links like NH 118 or NH 548).
- Golden Quadrilateral: A highway network connecting India's four major metro cities: Delhi, Mumbai, Chennai, and Kolkata.
- North-South and East-West Corridor (NS-EW): Connects Srinagar to Kanyakumari (North-South) and Porbandar to Silchar (East-West), intersecting at Jhansi.
Solved Examples (Step-by-Step)
Question 1
Which of the following is the longest National Highway in India?
Options: A) NH 27, B) NH 44, C) NH 48, D) NH 16
Solution: NH 44 is the longest National Highway in India, stretching from Srinagar in Jammu and Kashmir to Kanyakumari in Tamil Nadu. Therefore, the correct option is B.
Question 2
Where do the North-South and East-West corridors intersect?
Options: A) Nagpur, B) Delhi, C) Jhansi, D) Hyderabad
Solution: The North-South (Srinagar to Kanyakumari) and East-West (Porbandar to Silchar) corridors intersect each other at Jhansi in Uttar Pradesh. Therefore, the correct option is C.
Question 3
Which organization is primarily responsible for the development, maintenance, and management of National Highways in India?
Options: A) Indian Railways, B) NHAI, C) BRO, D) CPWD
Solution: The National Highways Authority of India (NHAI), established by an act of Parliament in 1988, is responsible for the development, maintenance, and management of national highways. Therefore, the correct option is B.
Common Mistakes to Avoid
- Confusing the old numbering system with the new rationalized numbering system of National Highways.
- Confusing the intersection point of the Golden Quadrilateral with the NS-EW corridor.
- Neglecting minor details like the executing agency (NHAI vs. BRO, where BRO handles roads in border areas).

Frequently Asked Questions (FAQs)
Q1: Are questions from National Highways common in RRB Group D?
Yes, static GK questions regarding transport networks are very common in both RRB NTPC and Group D.
Q2: Do I need to memorize all National Highway numbers?
No, focus only on the major ones like NH 44, NH 27, NH 48, and major regional routes relevant to your state or zone.
Q3: What is the new numbering system based on?
The new system is based on the orientation and geographic location of the highways, where north-south highways have even numbers and east-west highways have odd numbers.
Conclusion and Final Tips
Mastering National Highways requires regular revision of important routes, termini, and key statistical facts. Keep practicing mock tests and stay updated with recent infrastructure projects in India to ace your RRB exam!
