Update: Slightly adjusted the geometry so that you can push the bridges all the way together now. This feels kinda natural but was not supported so far. Also made the seam between the bridges if you do that landbug-proof
Also: To make the bridges slightly more ususable outside of a competetive setting, I added a set of dirtroad extentions to widen the exit out of the dirt a bit (see picture 2)
The new extentions only work with the updated geometry to please just swap out the folders entirely.
This set includes all transitions from flat DirtRoad to Platform. That means they can be attached to all basic flat pieces, as well as every diagonal connector piece (black and white).
The fences are separate items to allow the blank bridges to also be used for jump transitions. In addition, I found that the fences on their own might make for interesting scenery along the edges of platform blocks and diagonal road pieces (of any kind).
Have fun.
