My wife reports that one lane was blocked off and six police cars with lights flashing.  She was on her way to Arcata at about 4:00.  I’ll check around the blogosphere, but all reports are welcome.

Another driver reports that it was cleared up, but a sizable protest remained, by 5:30.

Addendum:  NCJ Blogthing has some photos.  It looks like the protesters put some shelters back in, and the authorities removed them.  No indication of any altercations in the report.
