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.
