It has been a long time since Ocean Quigley (Art Director from SimCity 4) shared with us some insight on the development of the game.  It’s been, what, 8 years and that game still looks amazing and is played by many.  Well, he has just recently updated his blog to tell us about the road design and the different experiments he had to go thru to get it working.  It took them a year alone to get them to work properly – and there are still features they wished they could have implemented (like cost feedback and bridge construction).
