3D bridges in Doom and Heretic using custom things
I discovered a technique that uses a DeHacked object that works as a bridge for ports that allow walking over and under things. And it works quite well in Doom using the Doomsday Engine, I know it would probably work in vanilla Heretic as well. The only issues are that AIs can't walk on top of it, that the bridge itself is invisible and Heretic Hack Editor being outdated.
Here's the map for context
Though with Doomsday and DDE it should be possible to set bridge parts as extra entities, like ZDoom, and then either set them to have a model that fits the theme of each game or make them blank boxes that can have a specific texture or flat on the fly. And they could be part of the of the built in PK3s to make them available directly at the map editor.
In summary, it's something that already can be done but it could also be more widespread as an official feature since DE doesn't support any other kind of 3D structure.
