That closure notice on the Monterey County Public Works website has been there for months and months. So long I can't remember exactly when it first appeared, but possibly has been there ever since the Dolan Fire - after which barriers with "closed" signs appeared at the start of the dirt section of Tassajara Road (though with gap to allow access for those who wished). Those barriers and signs disappeared awhile back - but the website still has the "closed" notice. FYI the USFS does NOT consider it closed (whereas they did immediately after after the Dolan fire). So currently that notice seems to have nothing to do with the actual status of Tassajara Road, but possibly left there for some bureaucratic reason.
Which is a long way of saying that the notice has nothing to do with any possible scraping.
