After an NCAA game that might have caused an outbreak of heartburn across the state, fans flooded the streets around campus in celebration.
"My heart was racing. I couldn't breathe," said Liz Blevins of Lexington, who was out on Pine Street. "This is what Big Blue Nation is made of."
Police shut down traffic at a host of intersections around campus and advised citizens to avoid the area because of traffic backups.
After the game ended, fans on State Street began celebrating enthusiastically, and more continued to arrive. There was a lot of fist-pumping, some bottles being thrown, and many small fires were started. Fireworks also were heard going off in the area.
Never miss a local story.
Officers tried to keep celebrants out of yards, but fans kept coming up to take selfies with them decked out in their riot gear, and the police complied.
As of about 1:30 a.m., 13 people had been arrested for alcohol intoxication or disorderly conduct.
City officials said eight people had been taken to University of Kentucky Chandler Hospital with relatively minor conditions such as alcohol intoxication and facial lacerations. One person was taken after being knocked unconscious.
Officials said the crowd was estimated at about 2,000 at its largest, but some celebrants were starting to leave the State Street area, the epicenter of post-game partying, by about 1:30 a.m.
Just before 2 a.m., the city brought in street sweepers to clear out the last of the crowd, and police officers took to the sidewalks to tell revelers it was time to go home.
City officials said the celebrations were relatively calm, and compared to most weekends in Lexington, there was no substantial increase in police and fire runs.
"All we do is win, win, win," said J.D. Wald of Newport. "We got lucky tonight."
As the end of the game approached, police positioned themselves in yards along State Street, began taking down street signs and shut State Street and University Avenue down to all but pedestrian traffic.
But at that point, it wasn't clear whether there would be anything to celebrate.
Fans in Two Keys Tavern screamed "What is going on?" as Notre Dame brought the score to 59-53.
Employees at Wildcat Wearhouse had gotten their blue party lights out and were prepared to delight rabid fans with a new t-shirt design.
They tried switching televisions, changing rooms, anything they could think of to "change the mojo" of the stressful game.
Whatever they did must have worked.
As soon as the game ended, there was jubilation, and then employees quickly went to work printing Final Four t-shirts. Soon, customers eagerly lined up to buy them.
"When Notre Dame shot that three at the the last second I thought it was over, but God was on our side," said Theo York. "The luck was not on their side. Our guys played their butts off."
Before the game began, an estimated 600 people gathered downtown at the Kentucky Theatre to cheer the Cats in front of the big screen.
Bars on South Limestone were filled to capacity, with lines out the front doors, before the game even began.
Well into the second half, fans were still waiting to get into Two Keys Tavern.
Fans said they were mixed on who they would like to see the Cats play in the championship game, assuming they get there.
"It doesn't matter," said Brian Johnson, of Newport. "Wisconsin is next and they're shooting lights out."
