Bridge Sabotage Quest [Planet: VOELD]

So I didn't realize I got this quest upon getting to some bridge somewhere on this planet, but it doesn't show a map marker for me. I'm supposed to find some bombs but... does anyone know where this quest objective is exactly? (Edit: Asking for location of the bridge, not the bombs)

Thanks for any help. The Wiki just has the quest listed but doesn't have anything else as far as information goes.
