To celebrate both the 6th anniversary of SimCity 4 Devotion, and the 7th anniversary of the first release of the RealHighway (RHW) system (which, back then, was still the Rural Highway), the NAM Team will be hosting a special showcase in the "Of Special Interest This Month" (OSITM) section of the SimCity 4 Devotion forums for the month.
The NAM Team is currently hard at work on Network Addon Mod Version 31, which will mark the return to a unified, "monolithic" package for the NAM, in which all major component plugins will be merged into the NAM Core as a single download. The RealHighway system is among the the component plugins that will be part of Version 31's core, and it is currently undergoing a massive facelift, codenamed "Project 57", which will vastly improve stability, laying the ground work for long-awaited multi-level interchange functionality.
The team is planning to pull out all the stops for this showcase, and it is expected that a few new "weapons of mass construction" may be revealed the OSITM residency.
