How do you get from Delaware Memorial Bridge to the Tappan Zee?

To get to the Tappan Zee from the Delaware Memorial, continue straight when you get off the Delaware Memorial, and you'll be on the New Jersey Turnpike. Take that to the Garden State Parkway. Go north on the Garden State Parkway to where it ends. It ends at I-87 in New York. Go south on I-87 which is also eastbound I-287 because it's concurrent to I-87 and you'll be at the Tappan Zee.
