Civil Engineering

Civil engineering is a professional engineering discipline that

deals with the design, construction, and maintenance of the

physical and naturally built environment, including works

like roads, bridges, canals, dams, and buildings. (Wikipedia)

Highway Engineering

Highway engineering is an engineering discipline branching

from civil engineering which involves the design,

construction and maintenance of Highway Systems .

Highway Engineers must take into account future traffic

flows, design of highway intersections/interchanges,

geometric alignment and design, highway pavement

materials and design, structural design of pavement

thickness, and pavement maintenance.
