On an off I have to say DFW has a very confusing road system with strange frontage roads with weird loops, not like the simple frontages I see in Arkansas and Kenosha County WI. Found it very difficult to get to the Waffle House a half mile from my motel.
I-10 immediately east of El Paso has much the same freeway/frontage road configuration; if you're on a frontage road (single direction) and wish to get to something
behind you (like your hypothetical Waffle House), you need to (a) head to the nearest major intersecting street, (b) use the crossover curving under the freeway to the opposite-direction frontage road, (c) take that frontage road
back in the opposing direction to the
next crossing street, then (d) repeat the crossover process in reverse, and, finally (e) head down your original frontage road to the restaurant. This was the major stopping point when I was making numerous trips in the '90's ferrying my elderly parents from the L.A. area to visit family in SE Oklahoma. My late dad, who was generally the most stoical of folks, actually piped up regarding this very process (I think the restaurant in question was a IHOP), calling it a "fucking pain in the ass!" Unfortunately, given the TX urban frontage-road "philosophy", it's not at all uncommon!
