You do not wanna see what this arrow does!
Speeding onto the bridge from the Brooklyn side, Clint and Kate block the span as they are pursued by the Tracksuit Mafia and Echo. They make their final escape by leaping over the side and catching a subway car that takes them back into the city.
While footage may have been shot around the actual Manhattan Bridge for this sequence, the actors were all filmed on a soundstage with the backgrounds added later via special effects.
