High Density Street Layout
Great design to be used within a high density area of Residential/Commercial/Office.
Uses raised pedestrian walkways to encourage your citizens to walk, allowing for less traffic on the road, meaning services have free roam through the road network.
Speeds up the building of a large city.
To create more than one section together simply demolish one line of road along the perimeter of the square. Then connect up the pedestrian paths.
Disadvantage: Lots of squares without any deviation of pattern makes for a rather boring layout.
