Fans were relatively subdued early Friday morning following Kentucky's 39-point victory over West Virginia.
On State Street, the scene of some of the more raucous celebrations in recent years, fans were huddled in small groups immediately after the game. Those groups quickly turned into large crowds clapping, fist-pumping and shouting "Cats! Cats! Cats!"
State Street celebrants started a few small fires by igniting trash and T-shirts, but the crowds were not as large as in past years.
Police closed State Street to vehicular traffic at about 12:10 a.m. to protect pedestrians.
Never miss a local story.
Meanwhile, on South Limestone, clusters of police officers patrolled the popular bar district just off campus, but the streets remained open to traffic and there were no obvious problems. A few police officers watched South Limestone from the top floor of a hospital parking garage.
There was a happy, peaceful crowd at the Tin Roof restaurant and bar on South Limestone as the game ended at 12:02 a.m.
"It was awesome. Even though everybody knew they would (win by a big margin). People had money on it," said Sam Joe, 19, manager of a hookah lounge at South Limestone where customers cheered the game.
The city's Joint Information Center to field media questions posted a tweet shortly before 1 a.m. that it was closing because it was "a pretty quiet night."
"I think the weather and the late hour definitely contributed" to a calmer post-game atmosphere, said Susan Straub, spokeswoman for Lexington Mayor Jim Gray.
Bigger crowds are anticipated should the Wildcats advance from the Elite Eight into the Final Four.
In 2012, UK fans flooded State Street and the surrounding areas to celebrate the team's Final Four victory over Louisville and UK's victory over Kansas in the title game.
Celebrations last year reflected those of 2012. Beginning in the Sweet 16 and after every NCAA tournament game last year, people ran out of homes and apartment houses, throwing beer and shouting. Some burned couches, trash bins, cardboard boxes and other items.
Earlier this week the Division of Code Enforcement posted notices on doors warning residents against leaving indoor furniture outside. Meanwhile, personnel with the Lexington Fire Department placed door hangars on residences that urged citizens to celebrate responsibly.
