I am looking to have a few large scale models built. Models of United States cities. I would like scale models of city streets large enough for a full scale 3D car to manuever through. Only the streets, interchanges and expressways as they would appear in their actual setting. 2, 4 lanes etc. I do not require the models to contain buildings only the streets as they appear on the city grid.
a sample of the city grid can be viewed on aaccessmap.com or see attached file
Las Vegas is one of the grids I am interested in and you an use that for reference
