Where are these bridges?

Four photos from a very old folder. Based on the date, I'm fairly sure I took them on the flight home to Boston from attending Minicon in Minneapolis with silentmachine. But I can't find any record of that flight so I don't know what stopover city I might've gone through. Click on the image to see all four photos; do you recognize those bridges?

Edit: Commenters have identified the first bridge as the Throgs Neck Bridge and the second one as the Verazzano Narrows Bridge (both in NYC).
