Highway Engineering
Comparison among various road plans.
NOTE: Length of the road as per 3rd 20 years road plan.
Total length of the road={4.74*No of towns & village} or {road density * area} whichever is greater would be total length.
National highway and State highway
Length of NH=Total Area of state in km2 / 50
Length of SH = Total Area of state in km2/ 25 or {62.5 *No town in the state length of NH} whichever is maximum.
Length of major district road = Total Area of state in km2 / 12.5 or {90* *No town in the state length} whichever is maximum.
