Needs more attention to the Sci-Fi design. I see that you’re trying to achieve that by adding neons at road shoulders, but overall, the design should be improved - your build looks like a typical roadway.
Your improved design should have most of the materials in metal, with vibrant but pleasing colours to the eye. You search some from the web for inspirations, to get what I mean.
Overall, it is a good attempt and you should keep it up and stay consistent to improve! 
Ok, thanks for your feedback! I do definitely agree with the materials. 
Archimedes has always been kind of weird for when you work with extra objects going vertically (In your case, the railings).
A solution that COULD work is using a plugin like Buildv4, and Rotate via a selected point. In this case, a corner on the entire model. And then just resize align all the parts you need to connect together.
I’m unsure if Studio Build Suite has the same feature because I don’t use it. Hope this helps!
Ok, thanks, I couldn’t find the plugins you mentioned in the tool box, if possible could you send me the links? 
I know I might be two years late here, but if you’re going to go for a road that detailed, I recommend you try making a mesh kit instead that uses SurfaceAppearance. Though that method has it’s own restrictions/ issues. I.e collision fidelity, UV mapping, you’d need to make a section for a specific use case such as intersections, and the list goes on. I prefer it over the part based roads though since you can make a kit and then make another texture that is mapped to your existing mesh. Part based roads are still viable however. Do what you’re able to.
