The Utah segment of BL-80 is codified into Utah law as Utah Code §72-4-111. Every year, the Utah Department of Transportation (UDOT) conducts a series of surveys on its highways to measure traffic volume. This is expressed in terms of average annual daily traffic (AADT), which is a measure of average traffic volume for any day of the year. In 2009, UDOT calculated that an average of 2,370 vehicles per day traveled on BL-80 at the state line. This is a significant decrease from the traffic counts earlier in the decade, which measured 11,205 vehicles in 2006, 10,345 in 2005, and 13,840 in 2004. Twenty-one percent of this traffic consists of trucks.
