Southbound lanes of Interstate 25 have reopened Friday morning north of Pueblo following a crash involving Fort Carson personnel, according to Colorado State Patrol.

Officials with CSP said that at about 4 a.m., officers responded to a vehicle crash near Mile Marker 107 north of Pueblo.

Early investigative efforts showed a Ford Expedition had rear-ended a Fort Carson Joint Light Tactical Vehicle carrying a trailer. The JLTV was traveling with a convoy of other military vehicles at the time of the crash, patrol officials said.

Investigators discovered the Expedition rear-ended the vehicle with the trailer at speeds exceeding the 75 mph limit. There were three people, including the driver, in the Expedition, CSP said. Four soldiers were in the Fort Carson vehicle.

After the JLTV was struck, it rolled onto its top and came to rest in the center of the median.

“All four soldiers self-extricated and rendered aid to the occupants of the other vehicle before being transported to the hospital for precautionary measures. All three occupants of the Expedition suffered serious injuries and were taken to area hospitals,” CSP officials said.

Fort Carson said in a statement that the soldiers were taken to UCHealth Parkview Medical Center in Pueblo for evaluation.

The soldiers were from the 1st Stryker Brigade Combat Team on their way to Piñon Canyon Maneuver Site southeast of Walsenburg for a training exercise, the statement said.

Southbound I-25 remained closed for several hours before reopening shortly after 10 a.m. The driver of the Expedition, who has since been identified as a 29-year-old man from Denver, is being investigated for impairment, the Friday announcement states.

Soldiers are working to recover the vehicle and return it to Fort Carson. The vehicle that flipped replaced the Humvee in military operations, Fort Carson said.

There are no fatalities reported at this time.
