Both terms are probably OK, but the only ones I’ve heard are “Canal Street Bridge” or “Canal Street Lift Bridge.” Maybe the second one isn’t official, but it tells! - a.s.
You also have the Lumbar Street Crossing. You can use google streetview to get a shot from the middle of the track S to the bridge or N to CUS.
South of the bridge is the famous 22nd street crossing where the IC main crosses the PRR main. In former times, the ATSF turned west here from Dearboarn Station. THe GM&O has a connecting track to reach it’ rails. You may also find pictures of GTW or Wabash trains threading thru the junction to head south.
It’s true that Amtrak now qwns the track from 22nd North into CUS. Not sure who owns the former PRR or C&WI lines from there south.
Hmmm… this brings up another question then. How far from this bridge was the end of the PRR main? My dad worked for the PRR so I have a special affection for it (one which he didn’t share… but that’s another story).
