Old State Road (Milesburg to Waterford)
DuBois, Clearfield County, Pennsylvania
Marker Inscription
The first road to the northwest frontier of Pennsylvania. Opened to the Allegheny River in 1804. In this section, it followed, generally, the course of the Chinklacamoose Path. During the War of 1812, troops under Major McClellan were transported over it to Erie. Highway crosses the route of old road at this point.

The Story
Opened to the Allegheny River in 1804, the Old State Road was the first route to Pennsylvania's northwestern frontier, and in this section it traced the course of the older Chinklacamoose Path used by Native travelers. During the War of 1812 it carried troops under Major McClellan toward the fighting at Erie. Where the modern highway crosses here, it meets the line of that pioneering road.
Why it matters
Roads like this one turned Native footpaths into arteries of settlement and wartime supply, opening Pennsylvania's northwest to the young republic.
The story behind this marker
AI contextThe era
In the first years of the 1800s, the northwestern corner of Pennsylvania was still frontier in the fullest sense. The young United States, barely a generation old, was pushing settlement inland, and the wilderness between the settled east and the Allegheny River was thick, roadless, and hard to cross. To open that country, people needed a way through it.
This was the era of the Early Republic, when roads were nation-building projects. A cleared route to the Allegheny River meant farmers could reach markets, settlers could reach new land, and the government could reach a frontier it hoped to hold. Opened toward the river in 1804, this road was the first real artery into Pennsylvania's northwest.
And it did not start from nothing. Through this section it followed the general course of the Chinklacamoose Path, one of the older trails that Native travelers had used to move across this landscape long before the surveyor's chain arrived. The new road, like so many in early America, was laid over knowledge that came before it.
People & events
The road's opening in 1804 was itself the main event, a deliberate act of a young state reaching for its own far country. But its most dramatic moment came a few years later, when the nation went to war.
During the War of 1812, troops under Major McClellan were moved along this route toward Erie, on the shore of Lake Erie, where the fighting on the northwestern front was concentrated. A road that had been cut to carry settlers and goods suddenly found itself carrying soldiers and the business of national defense.
That shift, from a peaceful road of settlement to a wartime supply line, tells you how thin the margins were on the early frontier. There were few enough routes that the same one had to serve every purpose. Where the modern highway crosses the line of the old road at this point, it crosses the very path those troops once followed.
Its place in the American story
The story of this road is the story of how America was built, one route at a time. Before railroads and long before highways, roads like this one determined where the country could grow. A single cleared track to a river could open a whole region to settlement.
Its overlay on the older Chinklacamoose Path is part of a pattern repeated across the continent. Again and again, the routes of American expansion followed trails first walked by Native peoples, who had already found the practical ways through forest, hill, and river valley. The new republic's roads often inherited that hard-won geography.
And its wartime service during the War of 1812 connects this quiet crossing to a national struggle. The Lake Erie theater was crucial to that war's northwestern front, and the ability to move troops toward Erie depended on exactly these fragile inland roads. A local road, in other words, was part of how the young nation held its frontier.
If you visit
What you'll find here is a crossing point, the spot where a modern highway meets the ghost line of a road more than two centuries old. It takes a little imagination, and that's part of the pleasure: you're standing where an early American thoroughfare once ran through unbroken forest.
Look at the lay of the land around you and picture it without the pavement, without the clearings, without the town. This was the leading edge of settlement, a single cut through the wilderness toward a distant river. Every wagon, every settler, every soldier bound for Erie passed this way.
If you're traveling through Clearfield County, this is a fine stop for anyone drawn to the deep roots of American roads, the War of 1812, or the older Native pathways beneath our maps. It rewards the kind of traveler who likes to stand in an ordinary place and feel the traffic of two hundred years moving through it.

Clearfield County
Clearfield, PA · est. 1982
Clearfield County, formed in 1804 from Huntingdon and Lycoming, drew its name from the open 'clear fields' that early travelers found in the wilderness. Through the second half of the 19th century it was a great timber county, its loggers felling the forests and running rafts of logs down the West Branch of the Susquehanna between 1850 and 1901. The county seat, Clearfield, was incorporated in 1840.
Allegheny Portage
Shippen Township, PA · est. 1949
Long before roads crossed the mountains, travelers moving between the Susquehanna's West Branch and the Allegheny River faced a 23-mile overland carry that began at a "canoe place" near this point. Native peoples and later pioneers hauled their canoes north to Portage Creek, then took to the water again near present-day Port Alleghany. The route stitched two great watersheds together across the Pennsylvania wilderness.
Cambria County
Ebensburg, PA · est. 1982
Formed in 1804 from Huntingdon and Somerset counties, Cambria took a name meaning 'Wales' — a nod to the Welsh settlers who came to these highlands, dating back to Roman Britain's word for the land. The county became a crossroads of early transportation when the Allegheny Portage Railroad hauled canal boats over the mountains toward Johnstown. It was also the birthplace of Arctic explorer Rear Admiral Robert E. Peary.
Brady's Bend Works
Bradys Bend Township, PA
For a third of the nineteenth century, the bend of the Allegheny River at Brady's Bend roared with the work of one of America's great early ironworks. Founded in 1839 as the Great Western and later reorganized as the Brady's Bend Iron Company, it grew into one of the largest iron operations of its era, drawing on the coal and iron ore of western Pennsylvania. Most remarkably, it became the first works to roll iron rails on the western side of the Allegheny Mountains — feeding the very railroads that were then stitching the growing nation together. When it closed in 1873, it left behind a company town and the memory of a place where American heavy industry came of age beyond the eastern seaboard.
