Rio de Janeiro
I'm traveling this month to LA and i want to drive to SFO via de PCH.
However researching google maps i've noticed that some parts of this highway have closed parts and i'm not sure if you can still use it to go to SFO or i have to go back and get another way to reach it.
So now, i ask, how to proceed in these cases?
Due to a landslide in Big Sur a bridge collapsed, cutting off an entire section of Highway 1. They've had to completely demolish the bridge so it's unlikely to be open until fall at the absolute earliest (but i'm guessing it'll be much longer). There's a good article here:
You can still do the drive for quite awhile up the 1 before you hit big sur, then you'll need to cut inland to the 5 in order to get to SFO.
Like you said, the road is closed because the heavy rains that we had in the last months. This area isn't prepared for that. You can reach the US1 in south of Big Sur and at the north of Monterey.
My recommendation is take the 101S and when you be near from Santa Barbara, you could visit Solvang, is a very beautiful city and not to popular.
You can also use the 5 highway but you don't have any nice city to stay at night if you're tired. The traffic from LA at beginning is always crowed and take at least 7 to 8 hours to do the all trip.
