Reminds me of the bridge story in Margin Call [1]. Or if you'd rather read it, here's the script [2], just search for "Did you know I built a bridge once?". Or condensed:
"It went from Dilles Bottom, Ohio to Moundsville, West Virginia. It spanned nine hundred and 12 feet above the Ohio River. 12,000 people used this thing a day. And it cut out 35 miles of driving each way between Wheeling and New Martinsville. That's a combined 847,000 miles of driving a day. Or 25,410,000 miles a month. And 304,920,000 miles a year. Saved. Now I completed that project in 1986, that's twenty-two years ago. So over the life of that one bridge, that's 6,708,240,000 miles that haven't had to be driven. At, what, let's say fifty miles an hour. So that's, what, 134,165,800 hours, or 559,020 days. So that one little bridge has saved the people of those communities a combined 1,531 years of their lives not wasted in a fucking car. One thousand five hundred and thirty-one years."
