PHOENIX – Last year, the Arizona Department of Transportation along with its maintenance contractors picked up 118,578 bags of trash along freeways in Maricopa County, which translates to approximately 811 tons. This continues an upward trend in the amount of litter accumulation along Valley freeways since 2017.

During the past five years, litter has steadily increased along state freeways in Maricopa County. In 2017, ADOT picked up 80,442 bags of litter compared to the nearly 119,000 bags last year. That’s a 47% increase.

ADOT maintenance crews are able to clean about 250 miles along the freeway system once a week thanks to funding from the Maricopa Association of Governments. Nevertheless, the amount of litter and trash increases along Valley freeways year after year. 

“Drivers can help out by simply not littering,” said Mary Currie, who manages ADOT’s Adopt a Highway programs. “Don’t toss that burger wrapper, paper cup or cigarette butt out of the window. All of those seemingly small and insignificant items build up over time creating safety issues.”

Some of those safety issues include blockages of stormwater drainage grates, sometimes preventing water from flowing freely to retention basins, drainage channels or pump stations. That can cause standing water to build in low lying locations along freeways. Over time, litter also can negatively impact the operation of pumps that remove storm runoff along some Phoenix-area freeways. 

It’s also important to secure your load before traveling. ADOT’s Incident Response Unit sponsored by State Farm, whose job is to patrol Valley freeways to provide vital services including removing litter and debris blocking the road, responds to an average of 26 calls per week for debris blocking the highway. In fact, one-third of all the calls the IRU receives are for litter blocking the road.

The Maricopa Association of Governments focuses on keeping roadways clean through its Don't Trash Arizona campaign. Those who litter along Arizona highways can face fines up to $500.

“By not littering and securing your loads, we can all help Keep Arizona Grand,” Currie said.

TUCSON - As part of ongoing efforts to keep highways clean, the Arizona Department of Transportation is devoting significant resources this week into removing litter from Interstates 10 and 19 in the Tucson area.

ADOT is deploying 45 staff members for the major cleanup along about 25 miles of highways, working along I-10 from Ina to Valencia roads, and along I-19 from I-10 to Valencia Road. Work began Tuesday, with crews expected to work 10 hours a day through Friday to complete the effort. While many of the ADOT personnel involved are based in Tucson, other crews are traveling from as far as Casa Grande and Nogales.

The litter problem is entirely an issue of driver behavior. Whether it’s individuals who throw trash out a car window or commercial vehicles that don’t cover their loads, the litter problem is preventable. While ADOT employees who live and work in the Tucson area are cleaning up the trash, it’s local residents and drivers who ultimately can help ADOT improve the appearance of highways by being more respectful of the environment.

ADOT maintenance personnel normally are available to perform cleanup duties as part of their duties, but their primary responsibility is to safety-related work such as guardrail repair, pavement maintenance, right-of-way fence repairs to keep livestock off roadways and other similar work.

ADOT is assisted in cleanups by volunteer groups who participate in the Adopt A Highway program, along with state prison inmate crews. Those crews have been mostly unavailable for nearly two years due to COVID-19 restrictions in prison complexes.

PHOENIX –  In the past two years since the Arizona Department of Transportation started the Incident Response Unit sponsored by State Farm, pickup of litter and dangerous roadway debris has been far faster and more efficient than before. 

The Incident Response Unit, whose job is to patrol Valley freeways to provide vital services including removing litter and debris blocking the road, is working even more efficiently with its own tracking system for calls and time management . The system has provided a clearer picture for the unit to see where improvements can be made in responding to roadway incidents in the Valley.

“Litter is an ugly problem anywhere and objects in the roadway can cause serious and even fatal incidents,” said David Blue, ADOT’s Incident Response Unit manager. “Our job is to respond as rapidly as possible to get the driving surface clear and make sure conditions are safe for everyone.”  

One improvement that has paid dividends was a shift in schedules to have a rotating member of the unit on patrol duty on the weekend to address the dozens of litter calls coming in. The Incident Response Unit sponsored by State Farm normally operates from 5 a.m. to 8 p.m. Monday through Friday with on-call services nights and weekends. This change keeps drivers safer by removing blocking litter more quickly and freeing up State Troopers to address other incidents on the freeways.

In fact, one-third of the 1600 calls that have come in since mid-August have been for litter blocking the road. The types of litter the IRU responds to range from ladders and load spills to couches and even air conditioning units.

“Having someone on weekend duty helps us achieve our mission of keeping traffic flowing and reducing the chance for crashes,” Blue added. “We’re always looking to improve our processes to better serve motorists in the Valley.”

In addition to litter removal, the IRU provides traffic control at crash scenes and aids stranded motorists. Having a dedicated mobile team has cut response times for incidents to a matter of minutes. Before the IRU, maintenance crews would have to stop their work, return to a yard to pick up vehicles and equipment and then respond to the crash scene.

Arizona Department of Transportation volunteers answered the call to participate on National CleanUp Day, Sept. 18, by removing more than 150 bags, or 2,053 pounds of trash from alongside Arizona’s highways. 

Forty groups from all corners of the state: Page, Yuma, Concho, Vernon, Show Low, Prescott, Chino Valley, Congress, Kingman, Lake Havasu City, Tucson, Bouse, Claypool, Sahuarita and Bullhead City, registered with ADOT for the event on the Adopt a Highway website. 

Adopt a Highway Program Manager Mary Currie said, “It’s a win for communities and the state of Arizona. One-day permits offer volunteers a way to explore one type of volunteer work among many, and to be a part of the litter solution. They get first hand experience on the process for adopting and how to conduct a litter cleanup safely. Our experience has been that some of these groups decide to complete the adoption for two-years and become regular caregivers of their segment”. 

More than half of the groups registering for the cleanup were new volunteers interested in participating for one day rather than a two-year adoption.

Every day Adopt a Highway program volunteers are giving back to Arizona somewhere in the state. ADOT strives to make it safe and as easy as possible for them to continue volunteering.  

These individual volunteers made a positive impact for drivers on the state highway system by removing all types of litter, including: cigarette butts, plastic bags and bottles, aluminum cans, and other unsightly trash. Car bumpers and refrigerator doors were also found along the way. A very dangerous type of trash for travelers.

Michele Michelson and her group of eight volunteers opted for a one-day permit to help clean up SR 89A in Prescott Valley. “We are all very proud to be here in this beautiful sunshine to keep the county, the town and our state clean. I saw ADOT’s post on facebook and registered. Here we are and we’ll do it again. Who doesn’t want to keep their community clean. Thank you ADOT for offering this opportunity.”

In return for a two-year permit and a sign recognizing their group’s segment, Adopt a Highway volunteers agree to:

Adopt a minimum of two miles of state highway

Always wear Federal Highway Administration required ANSI Class II Safety vests

Read a safety brief and watch a safety video before each cleanup

Contact ADOT before cleaning up their sections

File an activity report after each cleanup, telling ADOT how many bags of litter was collected

Clean their sections at least once and preferably three or more times per year

Motorists can support Adopt a Highway volunteers by slowing down where people are picking up litter and always driving with extra caution and care.

TUCSON - In an unprecedented push to remove roadside garbage and debris, 42 Arizona Department of Transportation employees from southern Arizona were recently able to pick up 11,000 pounds of trash and bulk items.

ADOT personnel from Casa Grande, Coolidge, Nogales, Oracle, Three Points, Tucson, and St. David cleaned up a stretch of Interstate 10 from Rita Rd. to Kino Blvd.; a distance of about 11 miles. This portion of the highway is a hot spot for roadside garbage and debris and the cleanup required approximately half of the available ADOT South Central District maintenance staff. 

“We did this because of an overwhelming amount of roadside garbage and debris on ADOT right-of-way,” said Highway Operations Supervisor Fernando Murrietta. “The problem isn’t just how much litter there is, but how it gets there. People throw trash from their vehicle and it’s ADOT crews who live and work in southern Arizona who pick it up. We are part of the solution because we’re cleaning up other peoples’ messes.  Things would be much better if people would be more respectful of the environment.”

Maintenance personnel are available to perform cleanup duties as part of their ongoing work, but their primary responsibility is safety-related work such as guardrail repair, pavement maintenance, right-of-way fence repair to keep livestock off roadways and other similar jobs. 

In addition to ADOT employees, trash cleanups are conducted by volunteer groups as well as state prison inmate crews. Inmate crews have not been available due to COVID-19 restrictions in prison complexes, but are now beginning to return to roadside duties.
