A scaled model of a single-lane road with a 4% cross slope and a 10' lane width as recommended by NACTO and the Texas DOT. There are .STL and .STP files of a road section as well as files for a road section that includes curbs on both sides. There is also a .DXF file with the road profile that can be extruded along a path curve to make custom single-lane roads with the correct cross slope.
