You can, sort of. Highlight the blueprint, hit Ctrl+C, then paste it into a text file. Then share the text file.

As of right now that's the only way to do it. I believe the dev said he will add that functionality at a later time.

Please post the text dump from copying the blueprint

Have you tested a normal cloverleaf junction to see if it is better or worse that those?

Yes, my question too. How is this better than a cloverleaf junction. All that track crossing looks like it would slow things down.

Been testing it for a few days and so far no logjams!

I think I recreated the original post .. the OP can verify it is correct:

Well, theoretically the input to bridges are similar crossover (at least merge) points in a clover leaf. I have not tried these in a comparison. But I did post a copy of the OP's blueprint so we can test.

I'm also going point out OP is likely comparing against the 4-way junction, in the track laying menu that isn't a cloverleaf at all. And is basically a roundabout with an intersection in the middle, as it (and the base 3-way) have to be place-able without stone bridges unlocked.

Also kinda surprised no one has pointed out the normal signals in the middle of the interchange which should be chain signals, to avoid backups causing jams, and the lack signals on the outside tracks, which only show up one of the four tracks

Right, the included blueprints are very basic. There are a couple mods out there with blueprints in the workshop for people who are interested.

All the left turn cut the other lines, it won't be more efficient than a cloverleaf
