The Huey P. Long near New Orleans.  3X (one eastbound, two westbound).
The Crescent City Connector 3X (one eastbound, two westbound)
The George Washington Bridge (too many to count)
The Verazzano Bridge 5X as driver all EB, but too many to count as a child passenger.  Never liked the rip off tolls, so always returned to NJ via Manhattan and the Holland Tunnel.

The Sunshine Skyway original cantilever bridge 3X (one NB and two SB both post Summit Venture with SB span gone)
The Lake Ponchartrain Causeway once NB.
The Ed Koch Queensboro Bridge 5X (three WB on lower level, one EB on lower level and one EB on upper level on the contraflow lanes)
The Throgs Neck Bridge once NB (Bronx bound from Long Island).
The Whitestone 2X both going SB to Shea Stadium
The Tappan Zee Bridge 2X going NB
The Bear Mountain Bridge 5X (4 EB and 1 WB)
The Newburgh- Beacon Bridge 2X one each way

The Goethals, Outerbridge, Bayonne, Ben Franklin, Walt Whitman, and other NJ bridges out of the state too many to even begin to count.

2) Hell Gate Bridge, which requires riding Amtrak across it - something I have never had reason to do, and which is kind of expensive for something to do just to say I've done it.
3) Empire Connection swing bridge, which would require a second Amtrak ride.

Responding a bit late here, but you've never had a reason to head up towards Albany or up the NEC to Providence/Boston?

I have, but not by train. Doing it by train means not having my car when I get to the other end, which is logistically problematic when fulfilling your hobby requires driving.

I can understand that, though Boston is also a neat enough town to where one could surely find some reason to go that doesn't require driving...
