Guia Roji will not have new maps until SCT puts out their new maps - which could be years - unless Guia Roji switches to a new source for their maps. With all the road construction in Mexico in recent years both SCT and Guia Roji are way out of date.
If you do not have or use GPS there are other options. HERE maps I think is now something like GO HERE and they have free downloads for both Windows and Apple. You can download almost any part of the world. But I looked and they do not yet have the new road.
Then I looked on Open Street Maps and they have it. Below is how to get to Open Street Maps and how to get to the new road. You can mouse all over the world with this website but you have to find other ways to download it to your computer so it is available OFFLINE so you can look at the map and not use up data if you are a limited plan - as most of us who travel are.
So below I post a couple of Snipping Tool maps directly from Open Street Maps - one shows the overview whole route of the new road which apparently will be 37D. Then I zoomed into the intersection to show how the different ramps go. If you look at the web address I will post below you will see it include Lat Lon numbers - it will do this for any location you go to - so the Lat Lon will be part of the web address. Cool.
Just for fun here is another web address for Open Street Maps which shows that new road that will loop around Guadalajara - they only show the part that is now supposed to be open . . . https://www.openstreetmap.org/#map=10/20.6289/-103.2962 . . . Note the different Lat Lon numbers from the one below.

I made this clickable to larger size but they do not appear to get larger when I click.
