A freeway sign is useless if it can’t be read, and tagging is enemy No. 1 in the battle to maintain interstate signs. ADOT crews in a constant fight to win the war over graffiti came up with an invention to prevent tagging.
Graffiti shields have been installed around some signs on overpasses to prevent taggers from defacing the signs. The 2-foot black sign extensions were conceived by ADOT’s Interstate Signing crew.
Saving money replacing signs is only one benefit to the graffiti shields. Find out the other benefits and meet the man who invented graffiti shields in the video above.
