Question

Describe geographical factors which have influenced the pattern of roads in India. Support your answer with examples from different parts of India.

Answer 1

1. Terrain (Relief): 
   1. Plains: Flat and level land supports a dense road network.
      Example: The Indo-Gangetic Plain (Punjab, Haryana, Uttar Pradesh) has a well-developed road system due to its flat terrain.
   2. Hilly and Mountainous Areas: Roads are fewer due to difficult terrain, landslides, and construction challenges.
      Example: The Himalayan region has limited roads, with winding mountain roads like Manali-Leh Highway and Gangtok–Nathula road.
   3. Plateaus: Moderately developed road network; rugged surface increases construction cost.
      Example: Roads in Chhattisgarh and Madhya Pradesh face constraints due to rocky terrain.
2. Climate:
   1. Areas with heavy rainfall or frequent flooding see rapid road deterioration.
      Example: Konkan coast and Assam floodplains require frequent repairs and raised roads.
   2. Desert areas face sand encroachment and maintenance issues.
      Example: Rajasthan, especially around Jaisalmer, has special metalled roads like Jaisalmer–Barmer highway.
3. Soil and Drainage:
   1. Alluvial soils support good roads (easy to construct and maintain).
      Example: West Bengal and U.P.
   2. Poorly drained or marshy areas hinder road construction.
      Example: Sundarbans and parts of Kerala’s backwaters.
