Also amusing that big cities tend to have avenues where two roads are built side-by-side. I've cleaned them up and made them one way in each direction and it's wonderful 
yes, that's exactly what I intended. Unfortunately simutrans builds the connections between the streets and there is no way to prevent this, but you can delete them easily and free of charge. Two-lane roads are also easier to erase than built.
Thank you someone likes it.

The Station, i will look on.
