Gainesville, Va.
America Online (AOL) has expansion plans in Northern Virginia. Construction began in late 2000 on a new $555 million technology center in Gainesville, similar to the one AOL has in Manassas. Both are in Prince William County, Va. At the company's headquarters in Dulles, an $86 million expansion is under way with two new buildings where 1,200 employees will be housed. One of the buildings is nearing completion.
