(CNN) -- Los Angeles is no stranger to big disasters -- massive earthquakes, riots, Lindsay Lohan. But closing a 10-mile stretch of freeway for 53 hours, as the city will do on Interstate 405 this weekend for a bridge demolition? That's a different matter entirely.
To help outsiders understand how a freeway shutdown could evoke such dread, the L.A. Department of Apocalyptic Scenarios has prepared this guide to the most frequently asked questions.
Why is it called Carmageddon?
Because the National Weather Service refused to lend the city one of its hurricane nicknames. And because "Traffic Jam Vince" didn't adequately convey the horror of a total freeway meltdown.
Isn't everyone overreacting? It's just one freeway.
If your heart had a blockage, would you say, "It's just one ventricle"? Freeways are what make L.A. tick. We don't have an NFL team (and the Dodgers are on life support); we have the 5, the 405, the 10 and the 110. And we don't have seasons; we have morning rush hour and afternoon rush hour.
So, this isn't simply about closing a highway. It's about disrupting a way of life. The 405 is to L.A. what the Cubs are to Chicago: totally infuriating, yet we keep coming back for more.
Aren't there alternate routes?
Why don't people just stay home for the weekend?
And do what? Read? Don't make us laugh.
So how will residents cope?
Psychologists strongly advise against quitting the freeway habit cold turkey. Public service announcements urge motorists to spend at least one hour a day parked in the driveway with the motor running, simultaneously sending text messages and shooting at their neighbor's cars in simulated road rage.
Why weren't people given more warning about the freeway shutdown?
It's true that most of the publicity was fairly recent. However, the event was clearly prophesied in the Bible, which mentions the Four Hyundais of the Apocalypse appearing near the end of time.
What happens after the freeway reopens?
The movie version, of course.
