Arizona Department of Transportation officials say it was the first vehicle detected on I-17 travel lanes in Phoenix since the wrong-way system went into operation in January.
Officials said in June that more than 15 vehicles have been detected entering I-17 off-ramps and frontage roads. None of those vehicles entered the I-17 mainline and most drivers turned around in the correct direction on the exit ramps, ADOT says.
“We’ve never been able to see what’s happening at these ramps,” said Steve Elliott, a spokesperson for ADOT. “Thermal cameras show that many of them self-correct.”
The $4 million system includes 90 thermal detection cameras positioned above exit ramps and the mainline of the freeway between the Interstate 10 "Stack" interchange near downtown Phoenix to the Loop 101 interchange in north Phoenix.
