UPDATE, 3:18 p.m. : Larry Trask spoke with Mark Benzinger of local road construction firm Mercer Fraser a few moments ago. They talked about what it typically takes to get highways back open in these circumstances. Audio below:


UPDATE, 2:40 p.m .: The California Highway Patrol dumps a massive load of photos on us. Slideshow below:


UPDATE, 2:33 p.m. : Ann Jones of Caltrans gave Larry Trask of KHUM the agency’s “last update until Friday morning.” Tomorrow, it turns out, is a state holiday.

Basically, Caltrans has nothing new since the press release we excerpted a few moments ago. The agency is certain the road will be closed for at least “the next few days,” while the CHP is insisting on two weeks at a bare minimum. (See update at 2:00 p.m., below.) Audio below:


UPDATE, 2:25 p.m. : Larry Trask’s interview with Michael McAllister, superintendent of the Southern Humboldt Unified School District, is below. As noted previously, South Fork High, Redway School and the Osprey Learning Center are closed tomorrow and Friday:


UPDATE, 2:19 p.m. : From a just-issued Caltrans press release: “The mudslide is 600 feet wide, extends 1,500 feet above the roadway, and continues to move.”

UPDATE: 2:14 p.m .: Officials from the Southern Humboldt Unified School district tell KHUM’s Larry Trask that South Fork High, Osprey School and Redway School will be closed tomorrow and Friday.

UPDATE, 2:00 p.m.:  KHUM’s Larry Trask just spoke with Martin Abshire of the Redway California Highway Patrol office. Abshire says that the slide has “destroyed” the roadbed, and he fully expects that it will be at least  two weeks before any traffic at all goes across that stretch. He also warns drivers away from using the Briceland route as an alternative.

For his money, the “safest route” between here and there is Hwy. 299 to I-5 to Hwy. 20.


UPDATE: 1:32 p.m. : Welcome, visitors from sfgate.com . If you’re planning a trip to Humboldt this weekend, tune into KHUM Radio  at around 2:30 p.m. for an interview with Caltrans about what traffic on Hwy 101 is going to look like tomorrow and through the weekend. (Direct link to the KHUM stream  here .) 

Worse comes to worst? Alternate routes available here , though there should be better information by the weekend. Hey — you take a detour, you drive through some of the world’s most majestic and scenic trees. All good, right?

Most likely. Check back at the Lost Coast Outpost tomorrow. We’ll have updates and the latest driving information for you, just for you.

UPDATE, 1:14 p.m .: Caltrans’ Ann Jones tells us that engineers are examining the site, but she has nothing new to report at the moment. She’ll be on KHUM radio at 2:30 p.m. to give us all a new update. That’s 104.3 and 104.7 FM. Click here  to go directly to the KHUM stream.

UPDATE, 12:24 p.m.: Detours — click here for a post on what we know about your very bad options at the current time .

UPDATE 12:08 a.m. : Art Reeve of the Humboldt County Public Works Department spoke with KHUM’s Mike Dronkers.

Audio below.


UPDATE, 11:39 a.m .: The county public works department is closing county roads to commecial trucks (over 30 feet axle-to-axle.) All trucks will have to detour to I-5.

UPDATE, 11:28 a.m. : Mike Dronkers talks with KMUD News’ Cynthia Elkins, who describes the slide and confirmed that the CHP is forecasting a very, very long closure.


UPDATE, 11:14 a.m .: Cynthia Elkins of KMUD News tells KHUM’s Mike Dronkers that CHP is confirming that they expect the highway to close for two wee ks. TWO WEEKS . She was on the scene, and she describes and absolutely massive landslide that has buckled the road, and that continues to slide. 

Audio soon. Meanwhile, photos from Cynthia’s Flickr stream.


UPDATE, 10:50 a.m .: Er, what’s that now, @humboldtchp? We’re assuming this doesn’t mean precisely what it seems to mean at first glance.
