DENVER (KDVR) — Interstate 25 was closed near Pueblo after a train derailed Sunday afternoon. Multiple agencies reported and responded to the incident.

The BNSF Railway train derailed on a bridge over I-25 near mile markers 106 and 107 around 3:25 p.m.

Colorado State Patrol said both directions of I-25 would be closed due to train cars and coal on the road for an extended period of time.

Pueblo West Fire advises drivers to not travel northbound past exit 104 and advises drivers not to travel south past exit 108 as the interstate was expected to be closed for an extended amount of time.

CSP shared photos of the incident and told FOX31 that there was a semi-trapped.

CSP said the bridge was unstable, which was hindering crews from accessing the driver. Just after 9 p.m., CSP told FOX31 that the driver of the semi-truck died on the scene.

Maj. Brian Lyons with the Colorado State Patrol said crews were making sure the scene was safe for everyone working there, and that crews would be working through the night and in the days to come to figure out what happened.

“We will be diligent with our investigation to see what transpired and working on the state, local and federal level to answer as many questions as we can,” Lyons said.

The National Transportation Safety Board has launched an investigation. A total of 12 train cars derailed.

Multiple agencies asked drivers to avoid the area.

Alternate routes and detours

The Pueblo County Sheriff’s Office said drivers headed north on I-25 from Pueblo to Colorado Springs could exit at Highway 50 and go west toward Penrose and continue north on Highway 115.

PCSO advised southbound traffic from Colorado Springs to Pueblo to take exit 135 to Highway 115 south as an alternate route.

Both routes eventually lead to I-25.
