 Culturally, by postal route, and socially, the community is connected to cross-river sister-city Brownsville, for the two were long joined by the Amerindian trail known as Nemacolin's Path that became a wagon road after the American Revolution, but West Brownsville is a separate municipality.Brownsville was the first point where the descent from the Appalachians could safely reach the river down the generally steep banks of the Monongahela River.Between Brownsville and West Brownsville was a shallow stretch, usable as a river ford astride a major Emigrant Trail to the various attractive regions in the Northwest Territory, the first National Road, the Cumberland Pike (Now U.S. Route 40).
