Looks way better, but I would suggest baking down the normal for it to take it up to the next level.
What is isn’t going to change is the tips of the geometry of the connection on the street - that section is indeed something you could add more geometry too if you are concerned of it looking “poligonish”.
Before you do however, have a look at TombRaider’s 1 face - and realize that Ngons are just normal. Most players won’t even notice it.
Is it worth modifying? Depends on what your scene/performance needs to be. On mobile, this is already overkill for instance.
PS:
I have no idea what your end goal is, but you may want to make the pieces separate and modular at this point?
I’d suggest having a 1x1m base of Flat, 90degree turn, 45deg turn, and whatever else seems appropriate to create a kit you can use to generate geometry in engine by placing the items.
What you do need to remember is to then duplicate your working level, and use a new one that you merge the geometry in via Merge Actors function. This is actually critical when working with modular sets, because the less overall draw-calls you need, the better the performance will almost always be.
However, it also has to be done intelligently - don’t just go merging everything into one thing, that’s going to hinder performance instead.
