How To Build A Complex Network Of Roads?

[knowyouremeny]

Building some roads that are rather complex... there's 2 bridges and some other things that I need to work out as well (like the terrain)... here's a picture of something similar to what I'm trying to do:

Except what I'm doing is a tad bit more complex... I have to do a few forked roads as well as a parking lot.

I was thinking I should do extrude face along curve for the clovers, but should I use this for all of the roads? It seems like that may be the easiest thing to do... when I need to do the fork, I could split poly tool & then extrude... and when I want to attach a road to the parking lot, I could pointsnap the vertices...

Opinions/Thoughts?

I've done stuff like this for visualisation models.
Model and texture some basic building block road pieces:
single lanes
multi-lanes
road edges
central reservations
barriers
pavements

Then use ffds or flow path objects to deform road pieces to the required shapes and fix all the junctions.
