CHEYENNE, Wyo. — Some drivers returning to Colorado after watching the eclipse in Wyoming were stuck in traffic for more than 10 hours on Interstate 25 on Monday.

A drive that normally takes about four hours lasted more than 12 hours.

The backups stretched for miles and some gas stations ran out of gas, leaving some people stranded.

The Colorado Department of Transportation said there were approximately 5,000 cars per hour on southbound I-25 after the rare solar event. That’s about 1,800 more cars than normal.
