David Petersdorf is a problem-solver and his successful attempt to speed up the process of painting stripes on highways in Idaho has gained him “Maintenance Person of the Year” status from the Idaho Transportation Department. It’s also saved Idaho taxpayers about $115,000 in one year.

Petersdorf said his main goal was to save time.
“I decided if we could make the material last longer, we wouldn’t have to stop and refill so often,” he explained. “It was a cheap modification and I’m surprised it worked as well as it did.”
Petersdorf, a native of California, said he grew up around heavy equipment and always had a mechanical knack.
