So I'm trying to get more info on the route between Chicago to Austin. I see that there are two routes.
Route 1 is:
I-55 to St. Louis -> I-44 to Big Cabin (Oklahoma) -> US-69 to Denison (Texas) -> US-75 to DFW -> I-35 to Austin
The mileage on Route 1 is 1,111 miles from my house to Austin. Of course, I don't know the address I'd be going to in Austin, so this is not exact.
(And considering I-55 deals with St. Louis, I might tack on an extra 6 miles to bypass downtown traffic via I-255.)
Route 2 is:
I-57 to Sikeston (Missouri) -> I-55 to W. Memphis (Arkansas) -> I-40 to Little Rock -> I-30 to DFW -> I-35 to Austin
The mileage on Route 2 is 1,167 miles. Once again, I don't know the address I'd be going to.
I have a couple questions about Route 1. What is the general speed limit, excluding towns, on US-69 between Big Cabin and Denison? Is it 65 mph? 70? 75?
My guess is US-69 is 70 mph but *I'm not positive*, as my very few trips south or west involved me taking Route 2 up til Texarkana then US-59, or Route 1 up til Tulsa or OKC.
Can anyone give me any pointers on what I'd expect if I take Route 1, including the section between Big Cabin and Denison?
Appreciate any responses!
