BigSurCalifornia.org is reporting that Route 1 is open to through traffic, but that "it is a bit smoky in the northern section of Big Sur and Bid Sur Valley." This site also reports that next week there will be 1-way controlled traffic just South of the San Luis Obispo/Monterrey county line and that Route 1 will be closed overnight on Tuesday, August 9 near Lucia and the Big Creek Bridge.
Caltrans is reporting single lane controlled traffic too, but does not report that Route 1 is closed.
