Travelers driving back to California this afternoon should expect heavy traffic on southbound Interstate 15, according to the Regional Transportation Commission of Southern Nevada.
About 1:30 p.m., there was a 13-mile backup near the Nevada-California border, RTC said on Twitter. “Prepare for long delays.”
Sigalert, a traffic monitoring website, shows that traffic begins slowing down near Good Springs Road and further slows down until commuters pass Primm, when the average speed is listed at 70 mph.
