UPDATE: Idaho Transportation Department officials say U.S. Highway 95 south of Riggins is unlikely to open today. Officials hope to have the rock slide blocking it cleared enough for traffic to pass Saturday.
A rock slide closed U.S. Highway 95 this morning at milepost 188, in the Sheep Creek Area about 5 miles south of Riggins.
The Idaho County Sheriff's office said there is no detour or other route to get around the slide, and had no estimated time that it would be cleared.
Idaho Transportation Department and sheriff's office officials are en route to the scene.
This story will be updated as more information becomes available.
