Short jump back to keflavik:
for the construction site i have a new idea...i will try to explain it:
so there shouldn't be an construction site with one lane only.
Why not making a standard road piece where you can simulate that just new fresh asphalt has been laid. (with using different road textures)
so on the one part of the road piece there's the old asphalt. then a short piece only material like gravel (i mean the material on the way to a quarry) and next to the gravel part there comes the part with the new fresh asphalt.
near the street there could be placed some equipment like machines, materials, containers, signs etc.
the construction site could start near the roundabout and the sanbuilders could be placed along the road after the construction site.
new suggestion...what's your opinion?
by the way nice screenshots Purno!
