No, they just want you to acknowledge (on the radio) that you are familiar with the route.... which is directly over the highway, at 500 AGL. Sometimes, Snake Eye might ask you to vary slightly, to accommodate some training activity. The information about the restricted area transition route is in the AF/D. Can't remember where exactly, but maybe near the Gila Bend entry, or in the area where they talk about Special areas, like parachute and restricted areas.
***** edit **** found it, in the "Chart Supplement, Southwest" (what used to be the AF/D)
