BOISE, Idaho — Dozens of road signs line every street, but most drivers never think twice about where they come from. Inside the Ada County Highway District’s sign shop, an 8-person crew builds about 3,500 custom signs each year — and installs around 10,000 signs annually across Ada County.
Aaron Katchmar leads the team, which has ramped up production in recent years.
