It serves as a connection between U.S. Route&nbsp;89 (US-89) and SR-31 in Fairview.

==Route description== SR-231 begins at the intersection of State Street (US-89) and Milburn Road, proceeding north on the latter. After slightly less than a city block, the route comes to its northern terminus at Canyon Road (SR-31).<ref name="googlemaps">{{google maps |title=Overview of SR-231|url=https://www.google.com/maps/@39.6343202,-111.4405954,16z|accessdate=January 16, 2019}}</ref> The road continues to the north towards Milburn, but it is not state-maintained beyond the SR-31 junction. The entire length of SR-231 is {{convert|0.085|mi|ft m}}.<ref name=reference/>

==History== The road from Fairview north to Milburn was added to the state route system in 1912 as part of SR-32,<ref>{{cite web |title=Highway Resolutions, SR-32 |url=https://www.udot.utah.gov/main/uconowner.gf?n=200609131103141 |publisher=Utah Department of Transportation |access-date=January 9, 2019}}</ref> and in 1926 it became part of the original alignment of US-89.<ref>{{Cite web|url=https://www.davidrumsey.com/luna/servlet/detail/RUMSEY~8~1~33766~1171482:Utah-?sort=pub_list_no_initialsort,pub_date,pub_list_no,series_no|title=Utah|date=1927|website=David Rumsey Historical Map Collection|access-date=January 9, 2019}}</ref> US-89 was moved to bypass Milburn in 1937, and the old route between Fairview and Milburn was transferred to SR-91. The routes remained in this configuration until 1969, when SR-91 was removed from the state highway system in a mass deletion of minor state highways and transferred to local jurisdiction.

However, the short segment of former SR-91 between US-89 and SR-31 in Fairview continued to be used as the primary connection from northbound US-89 to eastbound SR-31, and vice versa. As a result, in the meeting of the Utah Transportation Commission on October 12, 2018, this one-block segment was re-added to the state highway system as SR-231.<ref name=meeting-resolution>{{cite web|url=https://utahdot.granicus.com/MetaViewer.php?view_id=2&clip_id=300&meta_id=25586|format=PDF|title=Resolution: Addition of State Route 231 in Fairview, Utah|access-date=January 8, 2019|publisher=Utah Department of Transportation}}</ref>
