SimCity 4 Network Addon Mod by the NAM Team
The Network Addon Mod (NAM) combines all transportation network-related fixes, additions and new creations that have been released so far. It will add countless new features to the existing network tools, such as new overpasses, highway onramps, intersections, ped-malls, a ground light rail network, roundabouts and turning lanes.

 A Big Thank You
Thanks goes first and foremost to the SC4 fansite admins, for creating and slaving over their sites in order to make them a vibrant SimCity 4 community. Without them, none of this would be possible. A very special thank you goes to the entire Simtropolis Modd Squad and all the members of Simtropolis who have contributed to this Network Addon Mod in its current form. Simtropolis has given the Modd Squad a valuable and necessary tool to create the contents of this Network Addon Mod. Without Simtropolis, this mod simply would not exist.

SimCity 4 is still going strong more than four years after the initial release, and new websites sprung up lately, most notable SC4Devotion and the German SimCityPlaza, which have been supporting the NAM team from the very beginning. While all the mods and website maintenance is done voluntarily, web hosting is not free. If you enjoy and value this mod, either in part or whole, please consider making a donation to one of those sites to help offset the costs of running the site.
