In-progress Highway Systems & Work / Re: usaush: United States Historic US Routes
« Last post by Jim on Today at 08:53:41 am »I have a US 20 historic route file from Highway63 that joins all of the Iowa segments currently in usaush and runs border to border. Since it covers the whole state, should this just be ia.us020his.wpt with blank fields for abbrev and city in the CSVs? If it needs a city, Highway63 has offered Waterloo, Fort Dodge, or Dubuque, as possibilities, or Sac City if we want one that is not on current US 20 at all and is not used for any of the previously-added segments.
