Historic U.S. 91 began in Long Beach, CA, and traveled north to Sweetgrass, MT. Arizona had a short section of the road that entered the state where Mesquite, NV is today, then traveled through Littlefield (paralleling the Virgin River) before turning north to enter Utah at the town of Beaver Dam.
The road was decommissioned in 1973 with the opening of Interstate 15 through Arizona. U.S. 91 and Interstate 15 were multiplexed between Miles 0 and 8 of Interstate 15 between 1963 and 1973.
Today, old U.S. 91 is Mohave County Route 91 and open to serve local traffic.
