LINCOLN, Neb. (AP) — A concrete monument to a teenager’s rite of passage has been demolished at the school district’s Seacrest Field in Lincoln.

The old tower for driver’s education instructors has made way for new bleachers and an expanded press box.

The tower hasn’t been used in more than three decades. In its heyday, the tower held instructors who could — in elevated safety — watch a dozen cars and use one-way radios to train the fledgling drivers. Former instructor Bob Eyth recalled that there was one word the teenagers needed “to understand right off the bat, and that’s stop.”

In the mid-1980s the state stopped reimbursing schools for teaching driver’s education, so most districts stopped the courses.
