Centreville is a census-designated place (CDP) in Fairfax County, Virginia, United States and a suburb of Washington, D.C. The population was 71,135 at the 2010 census. Centreville is approximately 20 miles (32 km) west of Washington, DC.
Centreville is served by three major roads. U.S. Route 29 enters Centreville from the west and is the main artery through the town. Virginia Route 28 enters from the south and interchanges with U.S. Route 29 in between Centreville's two main shopping centers. SR 620 (Braddock Road) has several stretches of pavement in Centreville. Finally, Interstate 66 comes from the south-west and interchanges with both routes before heading off toward Washington, D.C. in the east or western Virginia. The three roads are part of an interesting, if not frustrating traffic pattern. Drivers heading north on SR 28 are able to exit onto Interstate 66 eastbound, but they must use a one-mile (1.6 km) stretch of US 29 to access the westbound side of the Interstate. Likewise, eastbound Interstate 66's Exit 53 only provides access to SR 28 northbound; one must use Exit 52 and the same stretch of US 29 to reach SR 28 south.
The area is served by several Fairfax Connector bus routes connecting to the Metrorail system: 640, 641, 642.
