The north-south runway at Mitchell International Airport reopened Sunday night after being shut down over the weekend because of a pothole.
Airport maintenance crews patched the pothole Sunday, which was caused by the freeze-thaw cycle affecting the rest of the Milwaukee area following subzero weather last week and then above-freezing temperatures.
Flights were not affected because air traffic control operators switched landings and takeoffs to the east-west runway, said Mitchell airport spokeswoman Patricia Rowe.
The pothole was noticed Saturday afternoon. The runway reopened at 8:16 p.m. local time Sunday.
