Brownsville Road
Brownsville Road is a road between Pittsburgh, at Eighteenth Street and South Avenue in Allegheny County, Pennsylvania eastwards through Mount Oliver and generally highlands situated along or near the hilltops often overlooking the Monongahela River. It has had several names over its history, and was also known at the Red Stone Road and the period it was a Plank Road managed as a toll road, the Brownsville Plank Road, or the Brownsville Turnpike, or locally, as the area grew into a city, Southern Avenue.
Along its route, it would also travel through Westmoreland County and end at its start terminus in Brownsville, Fayette County, Pennsylvania. It was a heavily used emigrant trail during the post-Revolutionary War surge in expansion west over the Allegheny Ridge to settle the now safer, now open lands of the Northwest Territory until well into the 1850s as a westward emigrant trail.
Pre-history to the 19th century
The road follows the route of ancient trails and footpaths as did many Indian roads, along the highlands and connected to the road along the descent from the Cumberland Narrows mountain pass to the ford Monongahela River below the bluffs known as Redstone Old Fort Virginia pan handle to reach lower central Ohio and points west.It was a major route for travel by stagecoach and emigrants driving Conestoga Wagons to Northern Ohio. The road was also significant during the Whiskey Rebellion, particularly its southern half; when trans-Allegheny farmers rose in armed protest to a tax on liquor sent east by pack animal on the Cumberland-Brownsville Road—shipping distilled liquor was easier than shipping the much greater volume and weight of raw grains.
