SUMMIT COUNTY, Utah — Both directions of Interstate 80 in Summit County were shut down due to a hazmat incident Tuesday afternoon. By early Wednesday morning, eastbound lanes had all reopened and some westbound lanes were still blocked. But, traffic was moving through slowly.
A shelter in place for nearby residents had also been lifted.
On Tuesday afternoon, the highway was completely closed at mile marker 150 west of Wanship in Silver Creek Canyon.
Eastbound I-80 was reopened around 8 p.m.
Photos shared by the Park City Fire District showed an overturned semi-truck on the road. A spokesperson with the Utah Highway Patrol said the truck was carrying a liquid peroxide, which caused the hazmat protocols.
Residents in the Tollgate area were being told to stay in place and indoors until further notice.
