U.S. Route 101
U.S. Route 101, or U.S. Highway 101 (US 101) is a north–south United States Numbered Highway that runs through the states of California, Oregon, and Washington, on the West Coast of the United States. It is also known as (The Royal Road) where its route along the southern and central California coast approximates the old trail which linked the Spanish missions, pueblos, and presidios. It merges at some points with California State Route 1 (SR 1).
U.S. Route 191 in Utah
U.S. Route 191 (US-191) is a major north–south state highway through the eastern part of the U.S. state of Utah. 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.
