I was thinking we have 4 roads leading in each directtion so we could have something in the middle of the crossroads like a netherportal building. I hoped in to creative and came up with this, though we can't have the water around it as we don't have enough room but we could still have the middle building. Obviously in this screenshot the portals aren't lit but they would be in the world however as you need to stand in them to be teleported you can walk through them without a problem
If not directly in the middle of spawn then I can build a side road off west of spawn as no-one has built out that way yet.
