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 model is a support for 'YARN Bridge01 L4 DL3 -Si +Sh' (kuid2:124017:26035:1).
