Jack Herrity served as chairman during Fairfax County's period of growth during the 1980s, when the County, previously known as a quiet suburb of Washington, D.C.; became the high population center of the Dulles Technology Corridor that it is known as currently. During that period of growth, the Board advocated for the construction of Interstate 66 inside the Capital Beltway and for the Dulles Toll Road, as well as for a major expansion of Tysons Corner, Virginia, which now is home to many employers in the information technology industry.
