The present alignment of US-191, which stretches from Mexico to Canada, was created in 1981 through Utah. Previously the route had entered northern Utah, ending at US-91 in Brigham City, but with the completion of I-15 it was truncated to Yellowstone National Park and re-extended on a completely different alignment. In addition to a large portion of US-163, this extension absorbed several state routes: SR-33, most of SR-44, and SR-260.
State Route 30 (SR-30) is a state highway in the U.S. state of Utah. It is the only highway signed as a Utah state route to traverse the entire width of the state.

In 2009, the Utah State Legislature named part of the route the "Mike Dmitrich Highway", named after the Utah state senator, which generated controversy, as the state of Utah had previously joined with all the other states through which US-6 passes in naming all of US-6 the Grand Army of the Republic Highway.
