Hi
I will go to it tomorrow and will update anything I see that changed,

for the floating highways issue, it's just how it is in real life, the street is being deconstructed(surface is taken away, getting widen, adding another street on it's right) so marking it as construction=minor won't represent the construction correctly, it is somewhat of a mess right now, where cars have to go through the construction site to enter the gas station etc, 

what do you suggest as a fix for this issue?

regards
