PHOENIX — With graffiti an ongoing threat to interstate freeway signs mounted on overpasses, an Arizona Department of Transportation employee invented an inexpensive metal shield that helps keep vandals and their spray paint at bay.

In ADOT’s culture of continuous improvement, this innovation by Interstate Signing Supervisor Dudley Heller is referred to as kaizen, something enhancing productivity, safety, efficiency and more.

Heller’s aluminum shield extends diagonally away from the sides of signs like a hood, making it difficult for would-be graffiti artists to reach around.

“It’s worked quite well,” Heller said.

For an investment of $17.50 per square foot, the shields protect taxpayers’ investment in signs that cost as much as $10,000 to replace.

The shields protect drivers, as spray paint damages the reflective coating on signs and makes them harder to read at night. They also make things safer for ADOT workers, who’d have to replace damaged signs on overpasses.

So far, ADOT’s Transportation Systems Management and Operations Division (TSM&O) has installed the shields on signs along Interstate 10 in Phoenix and Interstate 19 in Tucson.

“We’ve saved a lot of money by doing this, not to mention the unsightliness of the graffiti being out there,” Heller said.

Consider that the safety gear worn by football players has the same purpose as a seat belt – help the wearer survive a violent collision.

So, it’s no surprise that the Arizona Department of Transportation and Arizona Cardinals left tackle and Captain Jared Veldheer have partnered to promote the importance of wearing a seat belt with the Seat belts. For life. campaign. On Arizona roadways in 2015, there were 258 unrestrained occupant fatalities, which accounts for 29 percent of the people killed in traffic crashes that year. Lack of seat belt use is annually one of the leading factors in traffic deaths.

“I wouldn’t play football without wearing a helmet and shoulder pads, and I won’t drive my truck without wearing a seat belt,” Veldheer said. “Being safe is being smart.”

For the Seat belts. For life. campaign, two public service announcements were produced – “Strong Man” and “Safety Gear” – and each has a 30- and 15-second version. The PSAs can be viewed at azdot.gov, ADOT’s social media channels – Facebook, Twitter and YouTube – and will also appear on television during the fall, thanks to ADOT’s relationship with the Arizona Broadcasters Association.

ADOT is excited to partner with Veldheer and thanks him for volunteering his time for the Seat belts. For life. campaign. Working with the seven-year NFL pro on the subject of seat belts is a natural fit. His left tackle position protects the quarterback’s blind side the same way a seat belt provides security against the unknown for vehicle occupants. In the past five years on Arizona roadways, there have been 1,205 unrestrained occupant fatalities.

“Buckling a seat belt is the easiest thing to do when you get in a car,” ADOT Director John Halikowski said. “Its sole purpose is to help you survive a crash. Let the seat belt do its job – buckle up.”

“More than one in 10 Arizonans don’t wear a seat belt,” added Alberto Gutier, director of the Governor’s Office of Highway Safety. “Needless tragedies continue because people aren’t wearing a seat belt and parents need to make sure their children are properly restrained, too.”
