Looks like 2 intersecting runways, each about .4 mi long and right in the center of the old Naval Base complex. May have been used by small Navy props to ferry people back and forth to ? There's a large open area at the North end of the N-S runway - possibly a big helo pad or a turn-around. There also appears to be a hanger at the South end of the E-W runway. Sorry, it's too small for a PHL
If so, that's the former Henry C. Mustin Naval Air Facility on the banks of the Delaware. It was founded in 1917 and closed in 1963 due to it's proximity to PHL. At it's peak, Mustin had three runways: 6135', 4000', and 3150' (aligned 9/27, 14/32, and 5/23, respectively).
Yep, I guess that EW road really was a runway (9/27) and there are 3. It seemed strange because it runs right beside all that housing, which I guess could surely have been built after 1963.
