Signs are everywhere on Arizona’s highways, providing information about speed limits, nearby locations, rest areas and more. But how and where are these signs made?
ADOT has a Sign Shop where signs big and small are produced. The shop can produce signs as large as 16 by 30 feet -- these are the big, green signs above highways. Signs are made of aluminum and many sign blanks arrive pre-cut in standard shapes and sizes. Others are screen-printed.
