Significance of the bridge scene?
I can't quite figure this one out.
First off, that bridge is HUGE. It takes Travis quite a while to cross it and we don't see the entire trip. Take a look at the freeway in the background while Travis walks. I've lived in a lot of places, and I'm not sure that many other locations have devoted the kind of land to freeways that Greater LA has. That thing is really wide! So, no mystery about the length of the bridge.
Then there's the dialog of the "Screaming Man". Sure, a run-of-the-mill crazy spouting off about the evils of the world, and by golly, he warned us all.
But what does that have to do with Travis? Is it just to show a contrast between him and his now relatively stable self and another man that is over-the-edge doomed? Or the outspoken manner of the screaming man compared to his recent stint as a mute?
Is the length of the bridge symbolic, to indicate the long distance of time Travis had traveled during his 4 year hiatus?
At any rate, I like how Travis gives him a pat on the back as he moves on.
