For a little more than a year, a spelling error on a sign on one of Atlanta’s most high profile interstates has gone undetected.

All this time, Philips Arena, home of the Atlanta Hawks and the Atlanta Dream, has had an extra “l” on a sign on the northbound Downtown Connector, the Georgia Department of Transportation said Monday.

“Thank you for bringing this to our attention,” GDOT spokeswoman Annalysce Baker said in an emailed statement. “Our guys will also fix the sign tomorrow.”

GDOT officials said they could not “break down the immediate cost of the sign” because it “was a part of an overall project.”

There is some good news, taxpayers.

“There will not be an extra cost to the taxpayers to fix the sign,” Baker said. “Our crews will look at the sign tomorrow. After they determine how to fix [it] then they will tell me know how long it may take.”

The misspelled sign isn’t the first one spotted on metro Atlanta interstates.

In August 2014, a sign on the Connector directed motorists to one of the state's highest-profile tourist destinations, the Georgia Aquarium. However, Aquarium was spelled A-Q-U-A-I-R-I-U-M.

That same year, the second "n" in "Gwinnett" was missing on a Georgia Gwinnett College sign along Highway 316.
