In the end, the U.S. team had the most golds at worlds - the first non-European nation to achieve the feat.
"It's been incredible - hot and cold," U.S. Alpine director Patrick Riml said Sunday. "The rest of our team is stepping up so big."
While Austria led in total medals with eight, the U.S. topped the International Ski Federation's table with four golds. Austria and France were next with two golds each.
"It's nice being in Austria and beating up on the Austrians on their home turf," said Ligety, who won in super-G, super-combined and giant slalom.
Overall World Cup champion Marcel Hirscher won the men's slalom title on the last day of the skiing world championships for his first individual gold medal at a major event. Ligety failed to finish when he lost his balance and his left boot clicked out of the bindings 15 seconds into his first run.
The United States will host the next skiing world championships in Colorado in 2015.
