There are various traffic hot spots you might hit, not just the Tappan Zee, depending on exactly when and from where you leave. eg: There can be slowdowns in/near Newark (the city, not the airport) and Westchester.
Keep in mind that as GM SDC is your friend. Just make sure the fare rules of whatever ticket you purchase don't constrain your possible routings. For example, you might book the 2:30 LGA-RDU non-stop and then SDC to an earlier flight with a connection somewhere (assuming seat availability and that the fare you purchase doesn't require non-stop travel).
