The Juab J is easily visible from I-15 as you pass the middle Nephi exit. It faces southwest on the east side of the freeway just north of the canyon.
As far as we could tell, it is unhikable. Google maps shows several trails leading to the J, but all roads led to dead ends. We tried the shooting range, and that was as close as we got. There were three different roads that looked promising, but none panned out. Surprisingly, the frontage road is fenced off and does not go through near the J.
