They certainly have. I remember news stories in the early 80s that said most of the small bridges in the US were built by the W.P.A. during the Depression.
The stories said that these bridges only had a life expectancy of 50 years, and by 1985 they would have all crumbled and collapsed.
Twenty two years later and still waiting....waiting....
Of course, and bridges and roads are rebuilt all the time. Does anyone seriously drive down the highway and wonder, “Gee, I wonder if the next bridge is going to collapse?”
