PHOENIX – The Arizona Department of Transportation has added large “Wrong Way” signs on Interstate 17 bridges and other structures between the Interstate 10 “Stack” interchange and Loop 101, facing in the direction of potential wrong-way drivers.
That’s the same 15-mile stretch where ADOT is installing a first-in-the-nation wrong-way detection and warning prototype that uses thermal cameras.
Placing these “Wrong Way” signs, each measuring 8 feet by 5 feet, is another way ADOT is testing countermeasures to get the attention of wrong-way drivers on I-17.
