I'm imagining the visual of the bridge in the movie adaption of Atlas Shrugged that's made of Rearden steel. Instead of Dagny Taggart and Hank Rearden in a streamlined locomotive, it's a massive, straining locomotive conducted by Tess the Mess and that funky looking fat Asian man-hater, followed by flat cattle-cars of tubblrs. And unlike the successful crossing of the John Galt Line, theirs simply plummets the moment the locomotive puts its full strain on the bridge, and gravity does the rest in a cascade of failure and buttery tears. You're right, that would be a good bridge.
