Best route from Hollister, Ca north to Santa Rosa, Ca

The tunnel is not a problem as Trucks and tour buses do it all the time, don't use the curb lane! Depending on time of day 880/580 can be a traffic nightmare. I would also look at 680 to 80 to 37 to 101 this will bypass most the bay area commute traffic and the bay bridge maze. Note 37 has been flooded and closed due to our liquid sunshine we have been having. Check with Caltrans if your are doing this soon.
