Roadway files include many symbol classifications (Interstate, US Highway, State Highways, Local Roads, Ramps, etc.), each of these have a different
symbology (color, thickness, label)
AS WELL AS a different
label (Interstate shield, US Highway shield, State Highway shield, local road name, or <null>).
When saving symbology as a layer file (.LYR) the label settings are not included, so I have to re-work label settings every time. It's very frustrating and a waste of time.
