We use quite a few resources to construct this page, and we try to keep it up to date (but that is not always the case!). We use mainly officialy sites, but many of the AARoads contributors also have sites of their own that have proven helpful in providing reference material for this site. To complete the AARoads Utah Roads and Highways pages, we have utilized a variety of resources including:

  • U.S. Census for population figures (mostly from the 2000 and 2010 data collection), geographical size, and demographic information
  • Rand McNally Atlas and Thomas Guides - to confirm exit numbers, exit configurations, and identify street names within urban areas
  • Automobile Association of America - for still more map research, especially current and vintage maps
  • Utah Department of Transportation (UDOT) Highway Referencing for including mileage, route locations, descriptions, mileposts, exits/interchanges, and various features along the route.
  • UDOT Highway Resolutions for all legislative history of various state highways, including applications to AASHTO to add, delete, and modify Interstate and U.S. highways in Utah
  • Wikipedia - if we can't find specific information anywhere else, the on-line encyclopedia may have additional information
  • Other resources include personal observations from hundreds of trips around the Beehive State and newspaper articles that are individually cited mostly for ongoing construction projects and completion dates

We try to cite any other sources used on individual pages where we can. If you should find any errors on the page (and we know they're out there), please don't hesitate to contact us.
