Hola and buenos días, fellow city builders! I need help on building a grid layout for this town/city. What I plan to do is build mostly suburbs and one downtown area with high density and high-rise buildings. Also, I was thinking of extending the highway but on the fence about it since traffic could be a bottleneck to fix.

Please let me know what to do by commenting down below. You can also send screenshots of this image with rough sketch or drawing of good grid layout. Gracias in advance, fellow city builders! : )
