It would take you all afternoon to read the filmography of the 6th Street Viaduct in Los Angeles. Until the current rebuild began, this concrete arch spanning the Los Angeles River and some railroad yards was in more movies, commercials and TV show episodes than any other bridge maybe in the world.
The
list on Wikipedia isn't even close to exhaustive.
It doesn't even touch the dozens or even hundreds of TV commercials filmed there.
Reasons why it got used so much?
-It's in LA where they make all the moving pictures.
-It's got a good view of downtown.
-It's in a place where it's not a huge problem to shut it down for a day or two to film something.
-It looked pretty good. Very neo-classical/LA-noir kind of vibe.
-It can also look 'bad'; gritty and industrial depending on which way you point the cameras. Certainly, underneath it looks shady and very "Escape from New York"
