I haven’t driven I-65 in Northern Indiana in a few years time…but even 20 years ago the truck traffic was insane
I got to the point, going between Chicagoland and Southern Indiana, that I preferred the much more relaxing, even if a bit slower, haul down US 41/IN 63/US 41 down to US 50/150 and over, versus down I-65, around on I-465, and then down then-IN 37/becoming I-69
I get the same feelings on I-57 between Marion and Mt Vernon in Illinois, at least until IDOT finishes the 6 laning project. So many trucks its just not comfortable to drive or even safe
