206 and 207 were once a route to South Shore that was a flatlanders demise. They used to be very steep and very windy, VERY!!!!!! The Highway Patrol used to find folks literally frozen at the wheel and afraid to move. Way back when we tried going up Kingsbury Grade in our 1959 VW bug, couldn't do it.
I really don't know why you want to go that way, I would just do 395 to 50 West. Going from Tahoe to 395 is easy and shorter but I go up 50 in the rig.
