Despite the "1" as the last digit in the number, US 91 is no longer a cross-country artery, as it has mostly been replaced by Interstate 15. The highway currently serves to connect the communities of the Cache Valley to I-15 and beyond. Prior to the mid-1970s, US 91 was an international commerce route from Long Beach, California, to the Canada–US border north of Sweetgrass, Montana. US 91 was routed on the main streets of most of the communities it served, including Las Vegas Boulevard in Las Vegas and State Street in Salt Lake City. From Los Angeles to Salt Lake, the route was built along the corridor of the Arrowhead Trail. A portion of the highway's former route in California is currently State Route 91.

The U.S. Highway runs 220.15 miles (354.30 km) from US 17 Business and NC 24 Business in Jacksonville, North Carolina north to Virginia State Route 143 at Fort Monroe in Hampton, Virginia.

Interstate 15 Business is a business loop of Interstate 15 (I-15) in Cascade County, Montana, United States, almost entirely within Great Falls. The route links I-15 with the center of Great Falls. As its business loop designation implies, I-15 Bus. terminates at I-15 at each end. The southernmost 0.83 miles (1.34 km) of the route from the interchange with I-15 to Fox Farm Road is designated, but not signed, as Interstate 315 (I-315).

U.S. Route 460 (US 460) in Virginia runs west-east through the southern part of the Commonwealth. The road has two separate pieces in Virginia, joined by a relatively short section in West Virginia. Most of US 460 is a four-lane divided highway and is a major artery in the southern third of the state. From Petersburg to Suffolk, US 460 is a four-lane non-divided highway. It is a popular alternative to Interstate 64 (I-64) when going from Richmond and other points in central Virginia to the Currituck Sound and Outer Banks of North Carolina, avoiding the congestion and tunnels of the more northerly I-64 corridor. The road passes through several small towns that built up at stops along the railroad line.

Within the state, US 41 is paralleled by Interstate 75 (I-75) all the way from Florida to Tennessee, and I-75 has largely supplanted US 41 as a major highway. Due to this, the majority of the highway is not part of the National Highway System.
