Blake's comment is correct. Through only might make sense for a covered bridge.

I second Blake's comment as well. We would only go "through" a bridge if it is an underground, covered or tunnel bridge.

Thanks, Blake. You explained it well.

Hi! We wouldn’t really say “go through a bridge.” If you did say this, I would imagine a bridge that has some kind of hollow structure for you to pass through. Maybe a tunnel bridge or something of the sort? Anyway, it’s much more common to hear “cross a bridge” or “go over a bridge”
