Leaping into the future, the transportation sector is taking innovation to new heights—quite literally—with the introduction of graffiti-removing drones. This isn't a scene from a futuristic film; it's happening right here on the overpasses and bridges of Tacoma, Washington.
The Washington State Department of Transportation, under the guidance of Mike Gauger and his team, is testing a pioneering drone technology designed to tackle graffiti in hard-to-reach areas. Equipped with a spray nozzle and tethered to a ground-based paint supply, these drones are set to revolutionize how we maintain our urban infrastructure.
Graffiti, while often viewed as an art form, can also be a significant public nuisance, especially when it defaces public properties and can even pose safety risks to those trying to remove it. Traditional methods of graffiti removal often involve hazardous setups and can be costly and time-consuming. In 2023 alone, maintenance crews in Washington spent over $815,000 and dedicated approximately 10,300 hours to the removal of graffiti.
Enter the drones. This method is not only safer but potentially much more efficient. Mike Gauger’s team is currently testing these drones, driven by a necessity for safer, cost-effective solutions. This initiative stems from a real need—frequent reapplications in graffiti-prone areas that put maintenance crews at repeated risk.

Drones have been employed for bridge inspections within the state, proving their worth by reducing the need for physical inspections, which are both dangerous and expensive. Gauger's "lightbulb moment" to use similar technology for graffiti removal is an excellent example of adaptive innovation—taking an existing tool and repurposing it for new, valuable uses.
Furthermore, the recent passage of House Bill 1989, which allocates $1 million to research traffic camera technology and includes funding for drone testing, signals legislative support for technological solutions to urban maintenance issues. This backing is crucial as it not only funds the immediate needs of the pilot program but also sets the stage for broader implementation if the results prove successful.
The field tests slated for the remainder of the year in the Tacoma and Olympia areas will be crucial. These will not only test the operational efficacy of the drones but also refine their functionality based on real-world usage. Legal and safety considerations will also be addressed, as drones cannot currently fly over active traffic lanes.
While this pilot program is just a beginning and won't completely solve the problem of highway graffiti, it represents a significant step forward in the way we think about and handle infrastructure maintenance. It’s an exciting development that could lead to widespread changes in how public works maintain safety and cleanliness without putting human lives at risk.
This initiative could set a precedent not just for other states but for various sectors where drones might be used to improve efficiency and safety. As we watch this program unfold, it’s clear that the sky’s the limit for what innovative drone use might achieve next.
