More than 21,000 passengers flew out of Louis Armstrong International Airport on Ash Wednesday (March 1), bringing Mardi Gras 2017 to a close.
Here's a look at the Carnival season by the numbers, from portable toilets and booted cars to gun seizures and police overtime.
The parking crunch
With 3,000 temporary no-parking signs along parade routes, parking enforcement ticketed 29,561 vehicles on parade days. Enforcement officers also booted 397 vehicles and towed 729 vehicles on parade days.
Armstrong Airport was packed with an eight-year high for passengers during Mardi Gras. The airport estimates that 148,000 passengers will have departed from Feb. 24 through Friday (March 3), which is a 4 percent increase from last year -- and a 46.5 percent increase from 2010.
Police, EMS and fire overtime
New Orleans police, meanwhile, made 373 arrests and seized 39 guns over a 12-day period. Officers made 289 arrests -- including 32 gun arrests -- in the French Quarter, Marigny and Central Business District. Police found two guns on the street. Two of the confiscated weapons were BB guns, according to the NOPD.
Police logged a total of 54,150 hours during the 12-day period with officers on 12-hour shifts in police districts and a minimum of eight-hour shifts along parade routes.
New Orleans EMS responded to more than 3,200 emergency service calls -- a call every five minutes. First aid stations operated by the city health department and American Red Cross for 10 days helped 550 people and treated 118 people, 28 of whom were taken away by ambulance. The New Orleans Fire Department responded to 53 fires, 864 medical calls and 754 other calls for service citywide.
The city installed 650 portable toilets along the routes.
The messy aftermath
More than 600 city employees, contractors and temporary workers picked up parade remains every day from the streets and neutral grounds.
"This year presented a unique opportunity to show the world why New Orleans is the best in the business at hosting large scale events," Mayor Mitch Landrieu said in a news release. "As Carnival season began, we were in the midst of a tornado recovery and hosting the 2017 NBA All-Star game. Just as New Orleanians always do, we stood up with clear command and control, overcame adversity and continued our cultural traditions."
