Brownsville Road is a road between Pittsburgh, at Eighteenth Street and South Avenue[1] in Allegheny County, Pennsylvania eastwards through Mount Oliver and generally highlands situated along or near the hilltops [2] often overlooking (and sometimes taking shorter paths cutting across the loops of the meanders of) the Monongahela River.[a] It has had several names over its history, and was also known at the Red Stone Road[b] 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[c] until well into the 1850s as a westward emigrant trail.
