Historic National Road - Pennsylvania

The Historic National Road is the Nation's first federally funded highway. Opening westward expansion, it became a transportation corridor for goods and people, creating the great cultural diversity we treasure. Visitors experience a physical timeline -- classic inns, toll houses, diners, and motels that trace 200 years of American history.

Getting to the Byway: Pittsburgh, PA * Take I-279 west toward Rosslyn Farms. * Get on I-70 and go south to Washington. * Get on US-40 to enter the byway. Navigating the Byway: The byway begins on the border of Maryland and Pennsylvania, on what is now US-40. Addison, containing the historic Old Petersbug/Addison Tollhouse, is the first major town the byway (US-40) passes through. Continuing west on the highway, the byway will pass Fort Necessity and Braddock's Grave. Further along the highway, continuing in its northwesterly direction, the byway passes Forbes State Park, and then the towns of Hopwood and Union Town. Another stretch up the highway takes the traveler past the Searights Toll House, the town of Brownsville, and the Flatiron Bridge. The byway then crosses the Monongahela River and eventually passes through Centerville, Beallsville, and Scenery Hill, and passes by the Madonna of the Trail. As the byway nears the city of Washington, it intersects with Interstate 79, and then moves on to Washington, at which point the byway takes a southwesterly direction and intersects Interstate 70. Once out of the city, the byway passes the S-Bridge, and continues on through Claysville and then West Alexander and the state border with West Virginia, marking the end of the byway.
