Gainesville is a census-designated place (CDP) in Prince William County, Virginia, United States. Gainesville was once a changing point for stagecoach horses on the Fauquier & Alexandria Turnpike. In 1852, the Manassas Gap Railroad reached the area and the stop became known as Gainesville. It was a shipping point for grain, timber, and cattle and remained a major cattle shipping point into the early 1960s. In 2006, VDOT began working on the Gainesville Interchange improvement project in order to ease the traffic in the rapidly growing Gainesville-Haymarket area. It was completed in 2015.
Major commercial and residential development has taken place since 2000, resulting in Gainesville having six large shopping centers. The intersection of I-66 and Lee Highway (29 Highway) has the largest shopping center with big box stores, such as Target Supercenter, Lowe’s, Best Buy, DSW, Walgreens, and many other stores and restaurants. Somerset Crossing has a Bank Of America, Wells Fargo, and other shops. Close to US-15 are a Staples, Ross, Wegmans Food Markets, Michael’s, and Harris Teeter. The Promenade at Virginia Gateway was developed by The Peterson Companies, including BJ’s Warehouse, which opened in January 2012, and Regal Theaters which opened in late 2013.
The median income for a household in the CDP was $76,300, and the median income for a family was $82,627. Males had a median income of $46,934 versus $40,385 for females. The per capita income for the CDP was $35,196. About 1.9% of families and 2.8% of the population were below the poverty line, including 3.7% of those under age 18 and 0.6% of those age 65 or over.
