A new bypass around Mineral del Monte, Hidalgo, opened earlier this year. You can see at 18:15 in this video that the both the new bypass and the old alignment are signed as MEX 105 on brand new signs that weren't present in 2023 GMSV.
If I don't get to it in a week, please remind me.
Bumping, as requested.
Thanks. It should be in the next update, with MEX105 on the new bypass and MEX105Omi on the old route.
