And back to the subject of above ground networks - I am proposing the possibility of developing underpasses for the various types of networks (roads, one-way roads, and/or avenues under rail; road, one-way roads, and/or avenues under ground-level highways; and/or ground-level highways under all other ground-level networks) if they haven't already been created. If one or all have been created, please direct me to the download source. Thank you very much. Aside from this, keep up the excellent work everyone. The new and recent developments are amazing and further expand on SimCity 4's possibilities!! Thanks again! - Rooster
