LARIMER COUNTY, Colo. -- Southbound Interstate 25 was closed in northern Colorado on Thursday morning for more than 4 1/2 hours after an accident involving at least two semitrucks, the Colorado State Patrol said.
The crash happened about 5:30 a.m. just south of the Highway 392 exit near Windsor and involved a third vehicle that rear-ended one of the semitrucks.
The interstate reopened just after 10 a.m.
One of the semitrucks was hauling ammunition and a hazardous materials crew responded because of a fuel spill.
No injuries were reported, the Colorado State Patrol said.
Snow was falling in the area and sticking to the pavement at the time of the crash.
