Infrastructure engineering at WSU is an area of specialization in the civil engineering major. The field of infrastructure engineering combines transportation, geotechnical, and materials engineering. It deals with understanding and improving the capacity of soil to support the weight of our nation’s infrastructure and the various human and material design aspects of transportation facilities including traffic, geometrics, planning, pavements, and materials. Other examples of infrastructure engineering include preventing excessive settlement of new buildings or roadways, ensuring that tunnels retain their integrity, and maintaining the stability of earthen dams and embankments.

Graduates in WSU's civil engineering program are actively sought by employers. In addition to traditional architectural and engineering firms, infrastructure engineering graduates may work with government agencies, utility companies, telecommunications businesses, oil and natural resource industries, consulting firms, aerospace manufacturing companies, construction industries, and biotechnology and information technology firms. Salaries are comparable to other traditional fields of engineering and very attractive. As in all areas of civil engineering, the job market has remained steady over the years because civil engineers are always needed to design, build, and rehabilitate the nation's infrastructure.
