Addison to Uniontown
56.6 miles: 1 hours, 26 minutes
This portion of the drive carries you above the expansive Youghiogheny River Lake, which is bordered by tree-lined mountains. Mount Washington Tavern, a beautiful 1800s brick stagecoach inn, sits along US 40. It’s part of Fort Necessity National Battlefield; history buffs should visit the rest of the site.
Uniontown to Brownsville
13.5 miles: 0 hours, 28 minutes
This leg includes the river and Brownsville's Market Street (US 40). Two historic churches provide a nice contrast from the rural section of the route, which is dominated by hills and open expanses of land.
Brownsville to Washington
23.9 miles: 0 hours, 36 minutes
The bridge over the Monongahela River is a highlight of the drive trip. The elevated vantage point allows you to look down at the river and the borough of Brownsville and out at the forested mountains on the horizon.
Washington to West Alexander
22.4 miles: 0 hours, 41 minutes
On this leg, I-70 parallels US 40, but you’ll enjoy the slower pace of Pennsylvania’s Historic National Road. The road traverses some rural areas with tree-lined mountains as a backdrop. Claysville features historic buildings and a hillside cemetery.
