A train derailment spewed coal across a Colorado highway and killed a semitruck driver, authorities say

• A train derailed over a highway in Pueblo County, Colorado, on Sunday.
• Images from the derailment show a partially collapsed bridge with the semi-truck caught beneath.
• The derailment also caused a pileup of train cars and loads of coal to spew across the highway.

PUEBLO, Colo. (AP) — A semi-trailer truck driver was killed when a train derailed and a bridge collapsed, spewing coal and mangled train cars across a highway near Pueblo, Colorado, on Sunday, authorities said.

The driver has died, but no further details were available, Pueblo County Sheriff's Office spokesperson Gayle Perez said by telephone on Monday. No other vehicles were involved, Perez said.

The Colorado State Patrol and the sheriff's office posted photos and videos showing a partially collapsed bridge over the interstate with the semi-truck caught beneath. The images also show a pileup of train cars, train wheels scattered across the scene and loads of coal covering a portion of the highway. It was unclear when the bridge collapsed, state patrol spokesperson Gary Cutler said.

The National Transportation Safety Board was sending investigators to the site about 114 miles (183 kilometers) south of Denver.

President Joe Biden had been scheduled to visit CS Wind, the world's largest facility for wind tower manufacturing, in Pueblo on Monday, but postponed the trip to stay in Washington and focus on the growing conflict in the Middle East. The White House said just a few hours before Biden was set to take off for the trip that it would be rescheduled.

Pueblo is one of the anchors of Colorado's sprawling Third Congressional District, which covers more ground than the state of Pennsylvania. Rep. Lauren Boebert, a combative Trump loyalist, won the seat in 2020 and barely held on to it during the 2022 midterms. Boebert has described Biden's Inflation Reduction Act, the president's signature domestic legislation and the source of hundreds of billions of dollars for clean energy incentives, as "a massive failure" that "needs to be repealed."

A railroad bridge collapse in southern Montana in June sent railcars with oil products plunging into the Yellowstone River, spilling molten sulfur and up to 250 tons (226.7 metric tons) of hot asphalt.
