Southbound Interstate 25 north of Pueblo reopened Wednesday after a fatal train derailment and bridge collapse closed the roadway in both directions for three days.

Gov. Jared Polis announced the reopening after touring the derailment site with federal, state and local officials on Wednesday. The interstate reopened at approximately 3:15 p.m.

Colorado Department of Transportation crews are working to make available at least one lane of northbound I-25 by Thursday evening, according to a news release from Polis’ office.

Federal investigators said Tuesday they believe a broken rail just east of the bridge over I-25 caused the derailment and subsequent bridge collapse on Sunday afternoon. The incident killed a truck driver, 60-year-old Lafollete Henderson of Compton, California, and covered the roadway with coal and at least six overturned train cars.

Drivers should expect a rough driving surface on the damaged roadway as it’s being milled and repaved, according to state officials. There will be slightly reduced speed limits in the area.

In a statement, Polis said getting the highway back open is a top priority.

“Though the investigation is still ongoing, it remains clear that investments in rail are needed now more than ever and Colorado has been working for months to take advantage of historic safety and rail funding from the federal government,” Polis said.

CDOT Executive Director Shoshana Lew said the cleanup was an “all hands on deck approach,” and that BNSF Railway is taking the lead on rebuilding the bridge, according to a statement from the governor’s office.

CDOT crews have been working up to 22-hour shifts to reopen the highway, state Sen. Nick Hinrichsen of Pueblo said in a post on X.
