Washington County — Washington, Canonsburg & Peters Township

I-79 / I-70 / US-19 / PA-980

Washington County sits south of Allegheny County. The northern half of the county (closest to Pittsburgh) is heavily suburbanized and is often considered part of the 'South Hills' extended area. Anchored by the City of Washington (the county seat, home to Washington & Jefferson College and the Meadows Racetrack and Casino), Canonsburg (birthplace of Perry Como and the Four Coins), Peters Township / McMurray (one of the most affluent and fastest-growing Pittsburgh suburbs, home to a nationally-ranked school district), Cecil Township, North Strabane Township, South Strabane Township, Chartiers Township, and the Trinity area. The southern half of Washington County transitions to rural farmland and Marcellus Shale gas country.
