What’s the scoop on the Pacific Coast Salinas ACA bypass?

I’m nearing Salinas and wanted to know anyones experiences, I have a few questions:

• I hear there is no water for about 60 miles (King City to Paso Robles). Is this true? So far I’ve been good with 2 water bottles. I have a 3L bladder as well, will this be enough especially given the heat?
• it’s supposed to be hot (like mid-90s). How remote is this ride? Will there be shade? Will there be people passing by that could save me worst case?
• how is cell service? I have Verizon
