By the way, are all the tunnels double lanes? Do you need to find a wider passing lane when encountering oncoming traffic? I'm not confident about driving to the canyon area in the summer.. ?

The roads are good now, and the locals drive very orderly. You don't need to overtake frequently.
There are no navigation signals in the tunnel, but there are lights, and the lanes are bidirectional, with one or two lanes. There will be no need to pull over to avoid other vehicles, as everyone drives very responsibly and gives way to others.
