Utah Interstate Business Routes
The State Road Commission established the policies for signing Business Loops and Spurs in Utah in April 1973. The business routes would only be considered where less than four interchanges are provided for an urban area on the parent route. Business Loops will not exceed six miles in length or impose substantial out-of-direction travel for through traffic. Business Spurs were limited to no more than three miles in length.1
Interstate Business Routes also required at least two automotive service stations open 16 hours a day, seven days a week; at least one restaurant open for breakfast, lunch, and dinner seven days a week; lodging options with at least 10 rooms of hotel or motel space; a pharmacy open at least 12 hours a day, six days a week; and a public telephone.1
Cities meeting this criteria in 1973 and eligible for Business Spur signing included Payson and Springville along I-15, Salina on I-70 and Coalville on I-80. Business Loops could be signed at Beaver, Cedar City, Fillmore, Nephi, Parowan, Spanish Fork and St. George on I-15. Eligible cities along I-70 included Green River and Richfield, Wendover along I-80 and Henefer, Morgan and Tremonton on I-80N.1

We use quite a few resources to construct these pages, and we try to keep it up to date (but that is not always the case!). Additional assistance and reference material was provided from some of the AARoads contributors. To complete the AARoads Utah Roads and Highways pages, we have utilized a variety of resources including:
- CountyLemonade on Flickr – Site contributor Garrett Smith.
- @LanRovr0 – Site contributor Landry Heaton.
- 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 cannot 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 are out there), please do not hesitate to contact us.
