I've looked and looked and looked, but I cannot find any pre-9/11 photos of the underpass between One Liberty Plaza and the World Trade Center. The image below is of the eastern terminus, which survived in its original form. According to the original blueprints, the opposite side should have theoretically appeared identical. Have any of you actually used this passageway before 9/11? I want to do a feasibility study to see whether a free connection between One Liberty Plaza and the World Trade Center could be possible once again (currently, you'd have to spend a metro card swipe).
