This current closure map is from

Paul's Slide, which is just south of Lucia (where it says Limekiln State park) is being worked on, and hopefully will open in another month or so. Already it's open a few hours a day to locals and delivery vehicles only; so clearly they're making progress.
The new Pfeiffer Canyon Bridge is scheduled to be open by mid- to late- September.
Although I've recommended using Nacimiento Road in this and other threads, it's now not recommended. It's a small road, no more than 1 1/2 lanes in most places, and is now being used for large convoys of massive material trucks, hauling material for the bridge replacement. You can get stuck for a couple hours at a time on this road. Also, there are reports that construction workers are taking this road home, after their shifts, at dangerous speeds. There's already been one head-on.
They're still not saying much about the massive (one million tons+) Mud Creek Slide. The "very preliminary" guess of one year is still the latest communication from CalTrans. But the slide is still moving, and no one can guess at how long it will be before the geologists give the green light for
planning a fix. I've seen comments that people think that "one year" is wildly optimistic, and that it could take two years or longer to fix this.
