This is just a little idea to build a cul-de-sac lookalike-thing.....

...for this you can only use the 2 lane road...
....just put the small roundabout on the end of the road
...now you can build some residentials
....next step is to put some buildings next to the roundabout.....its a bit difficult cause the road-connection....should it not work you can build a tiny road-piece to place it....
...now you can decorate the inner and outer-roundabout with some trees and bushes
.....also you can fill the empty places between the residentials with some hedges and furnitures
....for more realism you can put some ploppable cars on the short road-parts
thats all....i hope that helps to build some suburban areas
MODS that i use for this:
