A kazillion roads have already been created for Trainz but, nevertheless, none of them seem to meet everyone's needs. So I've created Yet Another Road Network -- a set of models mostly suited for modeling U.S. roads. These probably won't meet everyone's needs either, but hopefully some people will find them useful. :p
This particular model is one way to end a four-lane highway. Each of the four lanes splits off onto individual merge ramps (which could then connect to another highway).
See the included naming-conventions.txt file for information about the attributes encoded in the asset's name.
