Leaving Las Vegas after Christmas? Join the crowd on Interstate 15, especially at the California-Nevada border in Primm.
On Monday afternoon, traffic was backed up 12 miles on the way out of Las Vegas to California, according to a tweet from the Regional Transportation Commission. Primm is about 45 miles southwest of Las Vegas.
More than 40 million people visit Las Vegas annually, with roughly a quarter of those coming from — and later going back to — California via I-15.
