RAS question

Which National Highway connects Delhi to Kolkata?

Correct answer: (B) NH-19 (old NH-2).

NH-19, earlier numbered NH-2, is the National Highway corridor that connects Delhi to Kolkata.

  1. (A)

    NH-44

  2. (B)

    NH-19 (old NH-2)

  3. (C)

    NH-27

  4. (D)

    NH-48

Explanation

NH-19 is the right answer because it is the present number for the old NH-2 corridor associated with the Grand Trunk Road. The NHAI executive summary describes NH-2 as one of India's major high-density corridors and states that it links Delhi and Kolkata. It also lists key cities on the route, including Delhi, Agra, Kanpur, Allahabad, Varanasi, Dhanbad, Durgapur and Howrah. The Delhi to Kolkata connection runs through the old NH-2 alignment, now referred to as NH-19. In exam terms, the important point is the renumbering: the historical or older label NH-2 and the current label NH-19 refer to the tested Delhi-Kolkata highway connection.

Why the other options are wrong

  • (A) NH-44 is the Srinagar to Kanyakumari north-south corridor, so it does not identify the Delhi to Kolkata route asked here.
  • (C) NH-27 is associated with the Porbandar to Silchar east-west corridor, not with the old NH-2 Delhi to Kolkata alignment.
  • (D) NH-48 connects Delhi towards Chennai via Mumbai and Bengaluru, so its alignment is different from the Delhi to Kolkata corridor.

Concept

This tests the Indian transport geography part of the syllabus, especially major National Highways and their renumbered identities. It recurs in RAS because highway corridors are a common way to link location knowledge with economic geography and map-based questions.
