	In December 2018, the Utah Department of Transportation (UDOT) announced plans for one of the largest wildlife overpasses in the United States. The structure was completed in 2019. It is 110 metres long, 15 metres wide and crosses six lanes of Interstate 80 (I-80). It is the second wildlife overpass in the state of Utah.
