The roads were packed Monday as visitors headed back to California.
The Nevada Highway Patrol warned about heavy traffic on Interstate 15 near Primm. The roads were backed up for much of the day, for as long as 26 miles, but subsided as the evening continued.
In addition to the traffic on the freeway, there were also backups to get gas and food at stops along the way.
Troopers suggested that drivers take State Route 160 to Route 372 to avoid the mess. The route will lead drivers to Interstate 15 in Baker, California.

Some drivers say they'll fight the traffic, just to avoid going out of their way.
"I've heard about it," says Matt Coulter of California, about the alternate route. "I just think it'd be a long way around from here."
Drivers can also take U.S. 95 through Boulder City, then head west on Interstate 40 to Barstow.
