I've been working on this for a short while, still quite early but I thought it looks cool already.
Here is a video. The bridge model I made myself in Blender then imported into the engine, and cloned it enough to make a long bridge.
Also, quick question - can I embed YouTube videos into my future posts? Or is it preferred to upload like I have here? I don't want to use up too much of the forums bandwidth this way, so YouTube seems better?
