Cars were stalled for more than an hour on I-25 Sunday after a dust storm shut down a portion of the interstate north of Pueblo.
The impacted area was between mile markers 114 and 116 on I-25.
A perfect storm of strong winds, loose undeveloped soil and the ongoing drought met Sunday to cause the enormous dust cloud that swept across the area. Visibility was so bad that even after the interstate was reopened, troopers escorted vehicles through the area.
"The visibility issue was something we could not in good conscience really let traffic go through there at full speed," one trooper told 11 News.
Drivers said they had never seen anything like it.
"I've never seen a dust storm like this," one driver said, adding that he agreed with the precautions the troopers took.
A soldier said the scene reminded him of Iraq, which is known for severe dust storms.
"It looked almost as bad as the ones we got out there," he said.
