No using laterals in Hermosillo, just make the left. There is construction work, as always, so the road has changed just a bit.
The Church's book is old enough that there is a big change.
Here are 3 options: Follow the Church's directions with these three changes. Shortly after your left turn, the construction begins, and traffic is one lane each say. There will be a detour sign, and you will be turned right. Then, very shortly, a left (unmarked), then very shortly, a left (unmarked). Then you are back on their directions. Then, at the end, when you had to get in the left lane to make a left as your last turn, there is now a nice overpass. You need to be in the right lane, not going onto the overpass. At the light underneath them, you turn left, and you are golden.
Option 2: Fall in behind a truck and follow them.
Option 3: Hire a taxi as you enter town, and have them lead you through. Might cost you all of 60p.
It's not hard, just relax.
