Still on the fence but has anyone been on Highway 30 between CR and Ames? Really want to go to the game but do not want to die.
I'm coming up from Johnston on I-35N.
To me it always comes down to the reliability of your vehicle and survival prep.
If you have a newer, reliable truck/suv, AWD/4WD, good tires, etc. You should be fine on hwy 30 if you drive smart & safely. Make sure to pack blanket, extra clothes, food/water just in case.
Obviously if you have no prep stuff in your vehicle and a rear wheel drive sedan with bald tires, don't do it.
IA DOT has all major roads as purple (not advised) but I've driven in that plenty. Red (impassable) is only on some smaller/off the beaten path roads. You do want to avoid any red or closed of course. Hwy 30 looks okay. Iowa State folks from DSM said I-35 is okay as well.
