1. PROFILE:

�Roads play major role in Rural development

� Important sectors like Agriculture, Electrification, Water

supply & sanitation, Health and Road are still under

process of development in India, especially in rural areas.

�These roads are either Track or Earthen having road width

of about 11 links (8 feet) & at the most 22 links (16 feet)

only.

•Connectivity for Poverty reduction strategy

. Good passenger transport facility, good

accessibility to all sphere of life i.e better

education, Health, better marketing facilities for

agriculture development, goods transportation

•Integration with higher category of roads.
