A computer glitch caused an hourlong traffic jam at the north entrance of Dallas/Fort Worth Airport on Monday as the airport's new parking system was not reading toll tags correctly.
"It was not registering every toll tag coming in to the north entrance or exiting the north entrance," said airport spokeswoman Cynthia Vega. "It led to a backup that lasted around an hour starting around 6:30 a.m."
The airport had staff manually lifting gates and issuing tickets to customers coming in to the north entrance that had toll tags.
The issue was identified but continued to crop up intermittently throughout the day until around 4:30 p.m. when it was fixed, Vega said.
The issue comes shortly after the airport installed its new automated parking system and was incorrectly charging customers with toll tags. The readers in the new system sometimes did not recognize when a car with a toll tag left the airport and was charging for a longer stay if the car returned at a later date and left again.
As of the airport board's October board meeting, the airport had issued $77,000 in refunds to more than 1,300 customers who were overcharged.
