Bridge northwest of Arborun?

I got a quest to find a fusion Arkadion northwest of Arborun but the only bridge i can find northwest of Arborun does nothing. Please help, thank you.

Have you checked every spot near the broken bridge west of Arborun?

I have, absolutely nothing. Have i encountered a glitch?

Moving to FAQ section, where you should post questions with objective answers related to the game. 

Do u have the quest? U didn’t drop it or anything.
Have u check the actual bridge because that where it’s at.
Make sure ur checking the lower bridge not the one in the wastelands.
That’s all I can think of
