The US state has seen eight people die as a result of wrong way driving and the new technology is hoping to stop unnecessary deaths by telling the authorities about a wrong way driver and also warning other drivers on the road.
The technology is set to be installed on 15 miles of Interstate 17 in Phoenix, between Interstate 10 and Loop 101, by the end of November.
Last week, the Arizona State Transportation Board voted unanimously to give the contract to Contractors West Inc., who specialise in electrical and sign work.
Speaking back in June about the introduction of the cameras, Governor Doug Ducey said in a statement: "I have instructed the Department of Transportation, the Department of Public Safety, and my Office of Highway Safety to convene immediately and increase efforts to mitigate and prevent this public safety issue.
"I have specifically ordered that the planned launch of thermal camera detection technology be expedited. I want those cameras implemented as quickly as possible, and expanded to as many areas as possible where they may make a difference and save a life.
"We also need to take some immediate actions to increase enforcement and public awareness. All of this needs to be done in collaboration with local law enforcement agencies. I want all Arizonans to know the state takes this issue extremely seriously. Our goal is to reduce fatalities and save lives, and we will take every appropriate measure in order to do so."
