sugetions for devs to add

[DIGOn27]

I am having some troubles with traffic so I thought about having underground roads.
And I also thought that the water on the map whould be more usefull if you needed to connect pipes from the water to the water towers; and this game really needs to have ships, and maybe an airport.
