Pavement failure near taxiway Foxtrot. RWY 07/25 closed for arrivals due construction of road underpass linking General Holmes Drive to Southern Cross Drive under the freight railway line and Botany Road.
A388 landed RWY 16L. Chaos would be one word, pandemonium might have been another. Local standby for the A388 arrival. At one point RWY 16L was closed as well as RWY 16R north of taxiway Golf.
All in a day of Sydney ATC, and that's only half the story.
