  • 80 % of the total road length in India.
  • There is regional variation in the density of rural road because these are influenced by the nature of the terrain.
  • Roads received special impetus under the Pradhan Mantri Grameen Sadak Yojana.
Border Roads
  • Border Roads Organisation (BRO) a Government of India - Border Roads and International Highways. Established in 1960.

  • International highways are meant to promote the harmonious relationship with the neighbouring countries by providing effective links with India.
Bharatmala is a proposed umbrella scheme for:
  1. Development of State roads along coastal border areas, including connectivity of nonmajor ports;
  2. Backward areas religious and tourist places connectivity programme;
  3. Setubharatam Pariyojana, which is for the consruction of about 1500 major bridges and 200 rail over bridges rail under bridges; District Headquarters Connectivity Scheme for the development of about 9000 km newly declared
