King County has posted the following message on their website:
"Southeast Middle Fork Road will be closed east of North Bend for three months, while the King County Road Services Division repairs landslide damage from winter storms. The road will be closed for three miles east of the intersection with Southeast Lake Dorothy Road. The closure will begin at 6 a.m. Monday, March 23, and is expected to last through mid June."
Second-hand information tells me there are now barriers and serious "you can't go in there" kind of road block. More to come after I investigate it personally.
