I've just started playing SC4 and believe I have it under control but for one thing.

I have residential space laid out and I moved some of the streets around. Now I have several of the "no road connection" icons, even though the spaces are on streets. I notice that each of these "no road connection" spaces has a ">" symbol on it that is pointing away from the street it is on. I think I need to get that ">" turned around and then the "no road connection" will go away, but I can't figure out how to do this.

I know that buildings can be rotated when they are placed by using the HOME and PG DN keys but I don't see any way to do what I want to do. I thought that maybe I could bulldoze the space and then make it residential again, but that didn't change the ">" orientation.

Any ideas?
