Has anyone heard of someone selling premade roadway assemblies that conform to county or city standards. It seems about 10 assemblies could be put together that cover most situations for a particular municipality. The only problem I see is if a company adopts different styles than the default for the assemblies, the standard ones would have to be modified.
It would save a lot of repetitive work for the 100 or so firms in each area to create their own assemblies.
