After attending
Washington State College for three and a half years, in 1922 he began work with the Washington Department of Highways engineering department. After holding public sector positions in Port Townsend and
Jefferson County, Washington, and working in the private sector in
Oregon and
California, he was recruited by
Washington Governor Arthur B. Langlie to head the state's Department of Highways. As the Director of Highways in
Washington state (1949–1963) he oversaw the design and completion of some of the state's most ambitious transportation projects including the
Astoria–Megler Bridge a span that crosses the
Columbia River near its mouth at the
Pacific Ocean. In 1953 he was recruited to fill the same position in the state of
California, but declined, stating his wish to complete projects in Washington. In 1963, however, he resigned his Washington position to become the project director in charge of design and construction of the
Bay Area Rapid Transit project in
San Francisco, California. In 1990, William was granted an honorary bachelor's degree from Washington State University and recognized as a distinguished alumnus, a status that had been granted to only 19 others in the history of the university. ==Later years==
