About this map

The Delaware River serves as the central artery for this industrial and maritime corridor, separating the dense street grids of Philadelphia from the growing suburbs of New Jersey. On the Pennsylvania side, the U.S. Navy Yard and Fort Mifflin dominate the southern riverbank, while Fairmount Park and the Schuylkill River define the northwestern geography. The landscape is heavily marked by a complex web of competing rail lines, such as the Phila. & Reading R.R. and West Jersey and Seashore R.R., which facilitate the movement of goods and passengers between the city and coastal destinations.

In New Jersey, the map reveals the distinct township structures of Deptford and West Deptford, where communities like Woodbury Heights and Blenheim Station emerged along these rail corridors. Waterways such as Cooper Creek and Big Timber Creek snake through the terrain, with industrial landmarks like the Alms House and several island features including Petty Id. and Hog Id. providing key reference points for researchers studying the region's early 20th-century development.
