The Academy Of Motion Picture Arts And Sciences is presenting a series of videos called Academy Originals with some Hollywood stories.
In this video, Special Effects Supervisor George Gibbs tells the story of that bridge scene in Indiana Jones and the Temple of Doom. They could only do it once, so it had to be perfect. Well, I guess they could have redone it if they had to, but that would add days and dollars to the film shoot. Oh, and in case you're wondering, a Bailey bridge is a temporary bridge. I knew that, because when the bridge in my hometown collapsed around 1970, a Bailey bridge was the only way through for a good ten years. -via the A.V. Club
