BOISE -- A hazardous materials leak on a commercial truck forced the closure of Interstate 84 in eastern Oregon for about 8 hours Thursday night, police said.
The interstate re-opened Friday morning after a haz-mat team cleared the scene.
Oregon State Police say a UPS freight truck hauling a load of Morpholine corrrosive liquid stopped on the exit 285 westbound offramp near North Powder after the driver noticed smoke coming from the trailer.
An OSP trooper stopped to help and then reported a haz-mat leak, police said.
Troopers shut down the interstate and evacuated several homes within a half-mile radius around the leak until the leak and contaminations were safely contained by a haz-mat team.
The Oregon Department of Transportation closed the eastbound lanes of I-84 at exit 261 in La Grande, while westbound I-84 was closed at exit 304 in Baker City.
Oregon Highway 237 was also closed near Union, and U.S. Highway 30 was closed to North Powder access.
According to ODOT there were no alternate routes available, and travelers had to wait until the freeway re-opened Friday morning.
