As Dr. Petley noted in his blog post, this looks like a classic planar rock slide where the rock mass failed parallel to the dominant planar discontinuity set. The slide occurred on Highway 70 between SR 94 and Clinch Valley Road. It will take the better part of a week to clear the debris according to TDOT. [Source: The Landslide Blog – AGU Blogosphere.

Video: Rockslide on U.S. Highway 64 in Tennessee
Amazing video of a rockslide as it happened yesterday along U.S. Highway 64 in the Ocoee River gorge in Tennessee. TDOT crews had almost finished removing rockslide debris from an event earlier in the day when a second slide occurred, blocking the road again. That looks like a pretty planar joint set dipping right into the roadway and everything was wet from the recent rains. Click through for the video.
