While the fight between the Black Order and the Avengers at the start of Avengers: Infinity War was actually filmed in Atlanta, some of the locations in the battle are in fact genuinely in New York, even though they may be simply be computer trickery. One of these is the area where the Spider-Man was beamed up into the ship as he tried to save Doctor Strange.
Uh, Mr. Stark, I’m Being Beamed up.
The location of this scene was at the intersection of 7th avenue, west 4th street, and Christopher street in Greenwich village.
The closest subway station is the Christopher Street station, and from here it is but a short walk to Washington Square park, the site of battle between Cull Obsidian and Iron Man.
