Washington County, Pennsylvania

Washington County is situated just south of Pittsburgh, bordering West Virginia. It has a bit of everything – farmland, suburbs, and some decent-sized towns. The Monongahela River forms its eastern border.
Oil and gas are big business here. So is gambling with the Meadows Racetrack and Casino draws crowds. Washington & Jefferson College adds a college-town vibe to the county seat.
There’s a lot of history too. The Whiskey Rebellion started here back in the 1790s. The county’s crisscrossed by major highways. You can still find some quiet corners though. It’s a place where old and new Pennsylvania meet.

The highway grid here works around the hills instead of through them. Though it sits just outside Pittsburgh, many areas feel surprisingly rural. Roads are practical, but not always direct. Our zoom tool in our road map below lays it all out so you can follow the curves.
