An early morning crash shut down southbound I-25 for about an hour at 1st Street in Pueblo.
As of 7 a.m., police have reopened the interstate.
The crash happened just before 6 a.m. Our reporter on scene says there is some dense fog in the area that may have contributed to the crash, though this has not been confirmed by police.
At least some of those involved were injured, but Pueblo police do not know how badly at this time.
