Philadelphia County, 1749

In this map section, the Delaware River is on the right (East), Cobb's Creek to the left (West), and the Schuylkill River runs vertically through the center. The Schuylkill's three main crossing points are (from top to bottom): the Upper Ferry, from Fair mount to the Haverford Road; the Middle Ferry, leading to the Lancaster and the West Chester Roads (the latter essentially a continuation of High/Market Street); the Lower or Gray's Ferry, connecting to the Darby Road (now Woodland Avenue starting at 49th Street). While Philadelphia City is shown as a grid between the Schuylkill and Delaware Rivers, this was intended only to illustrate the plan. In reality, the City existed only along the Delaware.
