This is Church Street in Philadelphia.  In front of that second car on the left is where the engine has to come out of.  Note that this street is one lane, and at the bottom of the picture the street narrows to less than one lane.  (That is if you have a large truck and a trailer)  There was also a parking lot just out of view on the left where cars could go around our trailer when it was parked in the narrow part of the street.
