Prefab steel ped bridge conduit routing

[u/burntalongtheedges]

I have to design a 2”rsc with fiber going across a prefabricated stainless steel ped bridge. My question is the transition from the end of the bridge to the pulling vaults I’m placing at each end of the bridge do you just have the rsc swoop out into the ground then the vault or add junction boxes? I would prefer no junction boxes because we will be sleeving the rsc probably. I have to worry about bend radius for the fiber so wanted to ask what others have done. It’s a 200’ bridge roughly.
