Metropolitan Utility District crews are repairing a gas main break south of the Eppley Airfield terminal.
The six-inch gas line was hit while a contractor worked on a sinkhole caused by Missouri River flooding, said David Roth, chief of Eppley's engineering wing.
Crews were called out about 1:20 p.m. to North 23rd and East Locust Streets when workers noticed a gas leak, Coufal said.
Operations at the airport were not affected, said Steve Coufal, executive director of executive director of the Omaha Airport Authority.
The sinkhole was 10- to 15-feet deep and the gas line is located seven feet below ground, Roth said. The break occurred near the airport's south long-term parking area.
Missouri River flooding has caused between 15 and 20 sinkholes on Eppley property this year, Roth said.
The gas was turned off about 1:40 p.m., said MUD spokeswoman Tracey Christiensen.
Four MUD customers, including an airport hangar, are affected by the gas shut-off, she said. Repairs should be completed by 6 p.m.
