They are: A hilly or mountainous area is characterized by highly broken relief with vastly differing elevations and steep slopes, deep gorges etc. which may unnecessarily increase road length.
What do you mean by Hill Road?
A hill road may be defined as the one which passes through a terrain with a cross slope of 25\% or more. There may be sections along hill roads with the cross slope less than 25\%, especially when the road follows a river route. Even then these sections are also referred to as hill roads.
