On July 22nd will be landing in SLC at 5pm and will end up driving to Jackson. I know part of this trip will be in the dark. I've tried to find when sunset is and get anywhere between 9 and 9:30 pm depending on the site.
AAA & Google Maps wants us to take I-15N to ID-34E to US-26E/US-89N.
MapQuest wants us to take I-80E to WY-89 to US-26 N/US-89 N
I read the What routes to take you to Jackson/GTNP from Salt Lake? from the top questions.
Honestly, that left me more confused about which route to take.
I'm looking for the most direct, less easy to get lost route.
