# Highway engineering

Highway engineering is the process of design and construction of efficient and safe highways and roads. It became prominent in the 20th century and has its roots in the discipline of civil engineering. Standards of highway engineering are continuously being improved. Concepts such as grade, surface texture, sight distance and minimum radii of bends in addition to interchange design are all important elements of highway engineering. With the exception of the U.K., most Western countries such as the United States, Japan and Germany have extensive well developed highway networks.
