Arizona DOT has issued a news release (link below) about a road buckling that has closed a section of 89 just south of Page, AZ. I figured this might be of interest to C-Brats who may be traveling to Powell, or who are just interested in general. I've only been to Powell once (so far!) and I came in from the north to Bullfrog, so I'm not sure of the routes people generally use to get to Page/Wahweap, but I know it's a common entry point to the lake.

"...the cause is not related to weather and may be a geologic event....ADOT crews are on scene and are deploying geotechnical engineers to investigate. It is not known at this time how long the road will be closed."
