My impression is that you are talking about the famous Triple Crossing (Seaboard bridge over C&O Viaduct over Southern at-grade).  However, this is right beside a bunch that are lesser known but more impressive in their own right: 

* Just to the east of Triple Crossing, the I-95 interchange with the Downtown Expressway (Toll VA-195) has also got the I-95 mainline bridge and two ramp bridges over the C&O Viaduct.
* Then just to the north of the Triple Crossing, three of the ramps from I-95 to/from the Downtown Expressway cross over the Seaboard Viaduct (mainline).  All of these are crossing over Dock Street (at grade).
* Next up is the I-95 mainline bridge also crosses over the Seaboard Viaduct (mainline) coming off the south end of Main Street Station, which crosses over US-60 (Main Street, at grade) at the same location.
* Almost, but not quite:  The Seaboard Interchange Viaduct (to the C&O) is just touching underneath the Downtown Expressway ramp to I-95 northbound.If you include the footbridge over the James and Kanawha Canal, there are six different levels of bridges intertwined at this location.  Not all of them stack.
