A runway at Dallas-Fort Worth International Airport re-opened Tuesday evening after being closed most of the day after a sinkhole developed in a nearby grassy area.
Runway 18L was temporarily closed as a precaution Tuesday for crews to assess the sinkhole, which was about 250 feet between the runway and a taxiway.
Officials said the sinkhole, 25 feet by 25 feet, was not located in an area called the safety area.
An engineering analysis determined the runway was safe to use and unaffected by the sinkhole.
Crews found a section of storm drain became dislodged, which eroded the soil around the drain and caused the sinkhole.
Construction crews will start making repairs on Wednesday morning, which will not require any closures of nearby runways.
The airport's other six runways remained open and unaffected by the sinkhole on Tuesday.
