UPDATE: The eastbound lanes of I-80 reopened around 9:00 Wednesday morning. The Nebraska State Patrol tells our news partners KSNB Local 4 that the crashed semi was carrying organic peroxide, which required specialized HAZMAT cleanup. Organic peroxides can be explosive, corrosive, and toxic and present extreme fire hazards.

SHELTON, Neb. - Emergency crews worked through winter weather conditions to clean up a chemical spill on Interstate 80 in central Nebraska.

The eastbound lanes of I-80 were closed between Shelton and Wood River because of the issue. Specific details are still scarce, but hazardous materials crews were summoned to the scene about two miles east of the Shelton exit around 8:00. The Nebraska State Patrol said at the time that the closure could be lengthy.

Roads are slick across the region as the first winter storm of the season blows through. Snow accumulations are minimal but have been substantial enough to contribute to multiple other crashes besides the one that forced the interstate closure.

Eastbound vehicles were being rerouted to use Highway 30.
