WEDNESDAY, NOV. 27, 5:45 a.m. ... Interstate 5 southbound into California remains closed this morning at Ashland exit 11.

One new closure: Caltrans reports U.S. 97 south is closed at the Dorris agricultural station.
Tranportation officials say common sense and safety are the key words today. They urge drivers to stay on maintained state highways and to not use GPS to try to navigate around closures.
"If an interstate freeway is not passable due to snow, please don't think an unmaintained or limited winter maintenance road is better," said Jeremiah Griffin, ODOT Assistant ODOT District Manager.
