Update: Highway One is now 100% open throughout Monterey County. Read this post for more information. Highway One in Big Sur reopened at Rocky Creek today! Here's the video: Drivers can travel Highway One from Monterey to Big Sur from 8pm to 8am daily. Plan a little extra time, as traffic is alternating one-way and there may be slowdowns. Big Sur is open for business and more beautiful than ever, and the folks there can't wait to see you!
