This week’s sweltering and dangerous heatwave has taken a toll on the bus arrival screen at the $1 million Super Stop on Columbia Pike.

The screen is currently out of service, with a large note apologizing for the problem.

“Due to the extreme temperatures, our monitor displaying bus arrivals is not operational,” the sign says. “We are working on the problem.”

Arlington County spokeswoman Laura G. Smith says technicians have ordered a new cooling fan for the display.

“It should be fixed within the next two weeks,” she said. In the meantime, the sign has instructions telling bus riders how to look up bus arrival times on their smartphone.
