Looks like under I95 only different shaped columns. I95 was partially shut down this week because of a weakened support.

They must have had Surface Cars under here-trolley cars that would also run underground.
I am glad to note that Phila. has resurected some of its' trolley car system.
We also have protective planks between the wires and the bottom of the 'EL' (Market/Frankfort elevated train) for when the cities "trackless trollies" used to run under the El.

Lately i visited a website named PHILLY H2O because I do research on the cities underground creeks (also a scary thought)
Amazing.
These histories are contingent with the cities sewer systems. A couple of hundred years ago many creeks were used as open sewers.A hundred years ago it seemed prudent to culvert these creeks and then fill over them.It solved several problems because now you could patent land and continue with the cities still developing plan of laying out streets in a grid pattern without having to deal with the many twists and turns of a stream.(newer developed neighborhoods do have twists and turns)
Also, you didn't have to worry about a bridge every time a new street was put through.
The subways-the Market/Frankfort line and the Broad Street line were simply bored through under an existing city.
Incidentaly my Grandfather worked on both sewers and subways in Europe when he was in his late teens.(he's long gone now as we're talking late 1890's,although he did live to age 94 )
