I'm playing around with ideas for a future trip (over a year out) from Chicagoland to the Orlando area. Using Google for routing:
* The shortest route is using IL 394, some back roads to the US 41/IN 63 corridor (not my favorite rural expressway), then down to I-24 and I-75 at 1,126 miles/17 hours 53 minutes
* Using US 41/IN 63, I-24, I-65 south to Montgomery AL then down US 231 to I-10 is 1,187 miles/19 hours 2 minutes
* Going over to Cincinnati and picking up I-75 is 1,185 miles/18 hours 29 minutes (allows clinching of additional sections of I-75 in Kentucky and Tennessee)
* Going through Indianapolis and then down IN 37/I-69 towards I-24 then using I-75 is 1,177 miles/18 hours 23 minutes
* Going over to Cincinnati, using I-75 to Knoxville then cutting over to I-95 using I-40 and I-26, plus using I-295 and FL 98 around Jacksonville is 1,222 miles/19 hours 21 minutes.
I've been on the I-65/US 231/I-10 route and the I-24/I-75 routes from Nashville to Florida before and experienced delays in Atlanta with the latter. I also seem to recall hearing I-95 may be one of those interstates that is overdue for additional lanes. Kind of curious what everyone's thoughts are on trying I-95 versus dealing with Atlanta.
