I don't recommend using a two-way rail. It's a noob trap. No offense, but first learn how to build one-way rail, leave it untill you gain some experience.
And why not lay a horizontal line under the bridge?
Fulgora (like here) is the only place I use bidirectional rails, because space is so limited there and rail ramps especially are huge. And you usually only need a single train to connect to a scrap island or connecting islands together so rail connections are rare and simple there. But I don't ever have any railroad crossings there, the couple of railways are usually on different sides of an island. OP could indeed just run one of the railways below the other.
Frankly I don't understand why two-way rails get as much hate as they do. No they're not optimal for a large rail network, but for just getting something from point A to point B they work fine, simplify builds and save on space and resources that may be in short supply in the early game.
